A modern home is not only a living space, but an intelligent system that works in your favor. In the face of rising energy costs and increasing environmental awareness, it is crucial to invest in solutions that ensure energy independence, reduce bills and minimize our carbon footprint. For us, the home of the future is a place where technology works for your comfort, and each solution is part of a larger, balanced whole.
The heart of an ecological and independent house is a photovoltaic installation. This solution allows you to produce your own free electricity, making yourself independent of increases in electricity prices.
An investment in photovoltaics is not only savings, but also a real contribution to environmental protection. The excess energy produced can be stored or transferred to the power grid, which translates into specific financial benefits in the net-billing settlement system. At Hymon, we design installations perfectly tailored to individual needs, maximizing their performance and your profit.
Modern houses need effective and ecological heating systems. Heat pumps are a technology that revolutionizes the way we think about heating and preparing domestic hot water. The device works with electricity, which makes it the perfect complement to the photovoltaic installation. In this way, you can use the energy produced from solar panels to power the pump, which in practice means almost zero heating costs.
Modern air conditioning systems are much more than cooling devices on hot days. These are versatile solutions that take care of the comfort and health of the household all year round. In addition to temperature regulation, advanced filters effectively purify the air of dust, pollen, allergens and bacteria, which is especially important for allergy sufferers. In addition, the reheat function makes air conditioning an effective and economical source of heat in transition periods.
In turn, the growing popularity of electric cars presents us with new infrastructure challenges. Having your own home charger (Wallbox) is not only a convenience, but also saving time and money. Thanks to it, you can charge your car at night using a lower tariff, or during the day, using free energy from photovoltaic panels.

Electric heating is one of the ways to keep the building warm. This solution is especially often chosen when there is no gas connection on a given plot, there is no space to install a liquefied gas or heating oil tank, as well as in the case of local legal prohibitions, e.g. pellet stoves. For electric heating, however, there is a very good alternative, which is heat pumps. In both cases, electricity is necessary for the operation of heating devices, but they differ in the way they work. The costs resulting from the investment and the operation of the devices are also different. Which one is better to choose?
The heat pump is a heating device whose operation is based on renewable energy sources. It does not produce heat on its own, but is only responsible for its transport from the lower source located outside the building (from the ground, water or air) to the upper source, i.e. the heating system inside the building. In this process, a small amount of electricity is necessary. In 75%, the operation of the heat pump is based on natural resources, and the current is needed only to drive the compressor. The devices available on the market include air heat pumps, ground heat pumps and water heat pumps.
Electric heating, in turn, is completely dependent on electricity. Among the available solutions that provide heat based on electricity, the most frequently chosen one is the electric stove.
The common features of electric heating and heat pumps include the possibility of their use in almost every building. The heat pump and electric heating are installed in new and old buildings (to modernize the heating system). These devices are easy to install, they do not take up much space, and they can also be connected to various heating installations (in the case of a heat pump, it is good to make sure that How to choose the right heaters for the heat pump?).
One of the key issues when choosing a heating system is the financial aspect. Both investment costs and operating costs should be taken into account. A heat pump is an investment that is associated with a higher expense at the beginning, but during operation it is much cheaper than electric heating – even four times. In practice, this means that the investment in the heat pump will pay off after about 7-8 years.
It is also worth knowing that you can get funding for a heat pump and take advantage of the thermomodernization relief by deducting the cost of its purchase and installation from income tax. This significantly reduces investment costs, accelerates return on it, and also increases profitability.
The factor that many investors take into account in the first place is the cost of the investment. Depending on the selected type and model of the heat pump, it will differ slightly. On average, the air heat pump with assembly for a house with an area of approximately 150 m2 will cost about PLN 35,000. PLN, and land – 60 thousand. PLN. In turn, the purchase of an electric boiler is an expense of about PLN 8,000. PLN, and the installation of the device – about 2 thousand. PLN.
The cost of the investment in the case of a heat pump is much higher, but the costs associated with the operation of the device should also be taken into account. The annual cost of heating a building with an area of 150 m2 with an air heat pump is about PLN 1,500, and heating the house with electric heating means an expense of about PLN 6,000.
The costs of using a heat pump are much lower than in the case of electric heating, thanks to which the investment, although initially expensive, pays off at a fast pace. The possibility of taking advantage of the tax deduction, as well as obtaining funding from programs such as clean air, make the investment in a heat pump even more profitable, and also reduce the initial financial outlays incurred.
When comparing a heat pump and electric heating, it is worth taking into account not only the costs, but also the functions of the devices. The heat pump is a multifunctional device that not only provides heat in the building, but also heating domestic water. What’s more, unlike electric heating, it can also cool the rooms (so there is no need to buy, for example, an air conditioner). The multifunctionality of the heat pump is one of its advantages.
Energy efficiency is another strong heat pump. These are highly effective devices – most good quality heat pumps are characterized by a COP (i.e. efficiency factor) at the level of 3.5-5.5. The higher the COP, the better, because less eclectic energy is used to generate heat. In the case of a COP of 5 per 1 kW of eclectic energy, a heating power of 5 kW is produced. The efficiency of electric heating is much lower – from 1 kW of energy it is possible to produce 1 kW of thermal energy.
The installation of a heat pump also offers environmental benefits. Heat pumps to a large extent use renewable energy sources, and only little use of electricity from the power plant. They can also be powered by electricity from a photovoltaic installation that covers all the demand for the pump’s electricity. The heat pump is the most ecological heating system on the market.
The electric boiler, on the other hand, is not an environmentally friendly installation, because the energy consumption of the boiler is very high. They use eclectic energy from power plants that emit harmful substances, including carbon dioxide. Often, even the installation of a photovoltaic installation does not meet the boiler electricity demand and it is necessary to use energy from external suppliers.
If you are facing a decision: a heat pump or electric heating, it is definitely worth betting on a heat pump. This solution is cheap to use, comfortable, ecological and energy-saving. Although the investment is associated with relatively high investment costs, it also translates into significant savings.
Solutions using renewable energy sources are popularized by financial support programs, which makes it possible to reduce investment costs. Owners of single-family residential buildings who want to install a heat pump or photovoltaics in their home, also have the option of deducting it from the tax as part of the thermomodernization relief.
Are you wondering if the heat pump can be tax-deductible? Such a possibility was provided for in the thermo-modernization relief. It allows for the deduction of costs related to the implementation of thermo-modernization projects from the tax base. The aim of its introduction was to encourage homeowners to undertake thermo-modernization projects, i.e. activities to insulate residential buildings and choose ecological heat sources.
According to Art. 2 point 2 of the Act on supporting thermo-modernization and renovation of November 21, 2008. The thermo-modernization project is considered to be:
Expenses for the purchase of building materials, devices and services related to the implementation of the thermomodernization project can be deducted from the tax.
Not everyone has the opportunity to take advantage of the thermo-modernization relief. The most important rule is the taxpayer’s settlement according to the tax scale, flat tax or registered lump sum.
It is also necessary to be the owner or co-owner of a single-family residential building no later than on the day of deduction. Therefore, the tenant, owners of multi-family buildings and people who are just building a house will not be able to use the settlement.
Expenditure on building materials, equipment and services related to the implementation of a thermo-modernization project may be deducted from income tax. It is important, however, that the total amount of the deduction does not exceed PLN 53,000. PLN. This amount is granted per one taxpayer, which means that if he is the owner or co-owner of several buildings, he is entitled to a limit of PLN 53,000. PLN for all projects carried out in them.
The tax deduction is made for the project completed within 3 consecutive years, counting from the end of the tax year in which the first expense was incurred. The deduction is made on the basis of the value from VAT invoices in the settlement for the tax year in which the expense was incurred. Invoices do not need to be attached to the settlement, however, they should be kept for at least 5 years, in the event of a fiscal control.
In the event that the amount of the deduction is higher than the taxpayer’s annual income, the legislator provided for the possibility of deducting in the next 6 years from the end of the tax year in which the first expense was incurred.

Thermomodernization relief is a solution that allows you to deduct from income tax expenses incurred for the purchase and installation of a heat pump. This significantly reduces the investment costs in this type of heating system, and thus increases its profitability.
It is also worth noting that in the case of using financial assistance from programs such as clean air, only the part of the costs that was financed from own funds can be deducted from the tax. The amount obtained under the grant is not deductible.
Heat pumps are heating devices that are known for their efficient, ecological and energy-saving operation, as well as many years of service life. Heat pumps can work flawlessly for a very long period of time, providing home heating, domestic hot water heating, as well as the possibility of cooling rooms. How many years can a heat pump work without losing performance? What factors influence its performance? How can the heat pump life be extended? See the article for answers to all questions.
A heat pump is a heating device that uses renewable resources from the environment. It consumes thermal energy accumulated in the ground, water or in the air (i.e. from the lower heat source) and directs it to the upper heat source, which is the heating system (i.e. radiators or plane heating, including underfloor heating). The heat pump does not generate heat on its own, but only transports it. Its work is also dependent on electricity, but supplied in a small amount, because 75% of the device’s operation is based on energy from natural sources.
The main task of the heat pump is to ensure the heating of the building, but the heat pump can also be used to heat domestic hot water. A large part of the heat pumps also has a room cooling function, so it can be used as a replacement for air conditioning.
Heating the house with a heat pump is also ecological, as the heat pump uses renewable energy sources. During operation, it also does not emit harmful substances, including carbon dioxide. It is an environmentally friendly solution.
A lot of good can be written about heat pumps – they are safe, energy-saving and convenient to use. However, the interest in the heat pump is mainly due to the low heating costs, which contributes to the development of savings. These are currently the cheapest heating systems in operation. Although it is necessary to incur considerable expenses on the investment, it pays off within a few years. The appropriate selection of a device for heat demand and the service life of a heat pump is of great importance for the profitability of the investment – the longer it is effective, the higher the savings compared to other heating methods can be obtained.
The technology used in heat pumps allows for their many years of and reliable operation. Choosing a high-quality device and carrying out annual inspections is a guarantee that the heat pump will provide heat in the building for a long time. How many years can a heat pump work?
The warranty offered by manufacturers for the devices in their assortment is usually 25 years. Therefore, you can count on so many years of failure-free operation of the heat pump. However, this is a minimum period – it is estimated that properly used and regularly serviced heat pumps can work for up to 35-50 years.
It is also worth noting that the life of the heat pump is tantamount to the life of the compressor, the operating time of which is determined in hours. This is usually around 100,000 hours. Taking into account the fact that the annual operating time of heat pumps is about 2000-3000 hours, the operation period of the heat pump can be estimated at 33 to even 50 years.
Several factors influence the performance and service life of the heat pump. These are:
The service life of the heat pump is approximately 25-35 years. The period of its operation depends to a large extent on the way it is used. What should you take care of to extend the life of the heat pump as much as possible?
First of all, regular maintenance and service are of great importance. They translate into failure-free operation of the heat pump, maintaining it in good condition, maintaining efficiency and extending the service life. It is worth taking care of annual inspections, as is the case with other heating systems.
Having an air heat pump, it is also good to take care of regular cleaning of devices, both during annual inspections carried out by professional service technicians and by the users of heat pumps themselves. Remove any contaminants such as dust, dust or leaves from the air intake and the fan. They can impede air flow, increase the consumption of electricity by the pump, and thus shorten its service life.
When faced with the choice of the method of heating the house, many people have a dilemma – there are many solutions available, which does not make it easier to make a decision. Factors that affect the final choice are, first of all, the costs resulting from the purchase of a heating device and fees related to operation. The comfort of use and the environmental impact should also be no less important.
Among the available solutions for heating the house are heat pumps and pellet stoves. If you are faced with the choice of these two heating systems, you will probably be eager to find out what their advantages and disadvantages are, and what is more profitable – pellets or a heat pump?
A heat pump is a heating device that uses renewable energy sources for its trowel. It takes thermal energy from the environment – from the ground, from water or from the air, and then, through a working medium, directs to the heating system inside the building. In 75%, the heat pump is supplied with energy from natural resources, only 25% requiring electricity. However, electricity consumption per heat pump can be radically reduced by deciding to invest in a photovoltaic installation (which provides free electricity, making the heat pump a cost-free device).
In recent years, heat pumps have gained enormous popularity, which is associated with their high efficiency, energy efficiency, low operating costs and the lack of negative impact on the natural environment. Thanks to heat pumps, it is possible to ensure high thermal comfort, as well as the convenience of using users, because it is a fully automated and maintenance-free system.
By choosing a heat pump, a multifunctional device is obtained – it is not only a source of heat in the building, but can also be used to prepare domestic hot water, as well as to cool rooms, acting as a replacement for air conditioning. What are the other advantages of heat pumps?
Heat pumps are not without drawbacks. These include, among others
Pellet is a fuel made from biomass, with a solid form, most often in the form of granules. It is made of pressed sawdust and wood chips. Pellet is one of the most effective sources of heating.
In single-family houses, it is possible to install a pellet stove, which provides heating of the house. The stove should be equipped with appropriate filters that reduce the amount of gases produced in the combustion process, and also have the appropriate size. It provides efficient and ecological heating of the house.
Modern pellet stoves are fully automated devices that allow for efficient and ecological heating of the house. They can be activated at the touch of a button, and within a few minutes the water in the radiators or in the underfloor heating heats up, ensuring thermal comfort. They also have an uncomplicated structure, so they are relatively easy to mount.
What are the advantages of a pellet heating system?
However, the pellet stove has its drawbacks. These include:
Ensuring heating of the building is associated with the necessity to incur certain costs, therefore the choice of the heating system at the stage of construction or modernization of the house is of great importance. Which heating device is more profitable – a heat pump or a pellet? And which, for various reasons, is better to decide?
In the previous part of the article, the advantages and disadvantages of both solutions are indicated and it cannot be denied that in comparison the heat pump is better than a pellet stove. First of all, the heat pump is currently the cheapest and most efficient system of heating and domestic water heating. Compared to the costs of heating with a heat pump, the cost of heating with pellets is much higher. The cost of heating a house 120 m2 in the case of a heat pump is about PLN 1,500 per year, while pellets are about PLN 2,500 per year.
It is also possible to reduce expenses related to the operation of the heat pump even to zero – the way to do this is to combine its operation with a photovoltaic installation, which ensures the supply of free electricity (which is the only cost of operating a heat pump).
The heat pump is also a fully automated and maintenance-free device – only the temperature appropriate for household members is set on it. Meanwhile, pellet stoves require specific work – adding fuel to the boiler, regular cleaning and maintenance from time to time. In the case of boilers, it is also necessary to provide a place for storing fuel, as well as having a flue chimney and separating the room for a boiler room. The heat pump can be placed in virtually any room. The heat pump also does not generate any waste, while the stove must be cleaned of ash.
The installation of a heat pump is also associated with ecology – during their operation, they do not emit harmful substances, while pellets emit impurities – although in a small amount. Heat pump heating is therefore better for the environment.
Heat pumps are also multifunctional – they not only provide heat, heat domestic water, but also cool on hot summer days. The pellet boiler has only the function of heating and heating domestic water.
An additional advantage is the possibility of applying for funding for the purchase and installation of both an air heat pump and a ground heat pump under the Clean Air program. Obtaining funding for a pellec stove, in turn, requires the device to meet certain conditions.
Recent years have seen a significant increase in the popularity of technologies based on renewable energy sources. One solution that uses natural resources is heat pumps. These are ecological, energy-saving and efficient heating systems that ensure high thermal comfort and convenience of use.
Heat pumps use various energy sources – from the air, from the ground or from the water. The most efficient solutions are currently ground heat pumps. How does a ground heat pump work? What is a heat exchanger? What are the advantages and disadvantages of installing a ground heat pump? Find out the answers to each of these questions!
The heat pump is a modern and innovative device that uses renewable energy sources for its operation. It takes thermal energy from the building’s surroundings, i.e. from the ground, from water or from the air, and then gives off heat to the heating system. In 75%, the operation of the heat pump is based on energy obtained from natural resources, and 25% requires electricity. That is why a perfect solution is to combine investments in a heat pump with a photovoltaic installation, which provides free electricity generated from solar energy.
Heat pumps are heating systems that consist of:
It should also be noted that the heat pump itself does not generate heat, but only takes it from the environment and directs it to the building. Due to the use of renewable energy sources, the heat pump is a very ecological solution. Moreover, during its operation, no harmful substances, including carbon dioxide, are emitted.
Heat pumps can use various energy sources – from ground, water and atmospheric air. Therefore, three types can be distinguished:
All types of devices have a similar principle of operation. They also consist of similar internal elements. The difference, however, lies mainly in the system of collecting heat from the environment, which affects the method of their assembly, price and efficiency.
A ground heat pump is a heating device that is to ensure the heating of the building and the preparation of domestic hot water. It takes heat from the ground and then, using refrigerant, delivers it to the building. The task of the ground heat pump is not to generate heat, but to allow its flow between the two sources – the upper and the lower.
Ground heat pumps are known for their high performance, which is the result of large deposits of thermal energy accumulated in the ground. The fluctuations in ground temperature are also small, regardless of changes in outside temperatures – it is a very stable energy source even in the event of a significant temperature drop below 0 degrees Celsius.
When considering how a ground heat pump works, it should first be noted that in the case of this type of heating system, it is necessary to install a ground exchanger responsible for the consumption of thermal energy from the ground. The heat exchanger is a pipe system placed underground at the appropriate depth. It is possible to install it in two ways – vertically or horizontally. The level collectors are laid under the ground surface on an area of even several dozen square meters, while the vertical collectors are placed deep into the ground. In the second case, drilling is necessary.
The ground exchanger is in the form of pipes made of plastic, which are filled with antifreeze, e.g. glycol. This fluid circulates in the pipes and receives heat from the ground, and then goes to the heat exchanger in the heat pump. The thermal energy taken from the ground is transferred to the refrigerant, which heats up, changing the state of concentration from the liquid to steam (this process takes place in a heat exchanger called an evaporator). The generated steam is directed to the compressor, in which its temperature is raised. The hot steam then goes to the condenser, in which the heat is redirected to the heating system, i.e. for underfloor heating or to radiators, as well as the installation ensuring heating of domestic hot water.
The decision on which home heating system to choose is crucial for ensuring thermal comfort, as well as a huge impact on operating costs. Is the choice of a ground heat pump a good solution? Here are the most important of its advantages:
Ground pumps also have their drawbacks, which include:
Heat pumps are heating systems appreciated due to low operating costs, convenience of use, no negative impact on the natural environment. It is the most effective, energy-saving, ecological and cheapest way to heat the house and prepare domestic hot water. That is why many people, when building or modernizing a house, decide to use a heat pump, while facing a dilemma – ground or air heat pump?
The lower source of energy in air heat pumps is atmospheric air, which is collected from the building’s surroundings. Thermal energy from the air is then directed through the refrigerant to the heating system inside the house. The heat pump can not only provide heating, but also cooling (it then removes warm air from the interior of the rooms) and for the preparation of domestic hot water.
There are two types of air heat pumps. These are:
Air heat pumps are currently the most popular. Their purchase and assembly is associated with much lower costs than in the case of ground heat pumps. In order to install an air heat pump, it does not necessarily have special permits, and the assembly itself is almost non-invasive. An air heat pump is also a small device that can be installed without special rooms for this purpose.
Ground heat pumps use heat cumulative energy in the ground. They collect it using the so-called Heat exchangers that can be assembled deep into the ground (vertical collectors) or in under the freezing surface, creating a network of tubes underground (horizontal collectors). The energy consumed is directed by the heat pump to the heating system inside the building.
The advantage of ground heat pumps is their high efficiency. They base their actions on a very stable heat source, which means they can work efficiently even at very low outside temperatures.
The installation of ground heat pumps is associated with the necessity to carry out earthworks or wells, which is why it is most often recommended for new buildings. Otherwise, it will involve digging up the garden, which is not always an option.
The purchase price of a ground heat pump does not differ much from the price of a device such as an air heat pump. However, due to the need for boreholes to install a ground pump, the investment costs increase significantly – even twice in relation to the air pump. In addition, you must have a plot of appropriate size, and the implementation of the task itself requires special permissions.
The decision to install a heat pump, regardless of whether it is a ground heat pump or an air heat pump, has specific benefits for investors. First of all, they are multifunctional devices that can be used both for heating and cooling, as well as for heating domestic water.
They opt for a ground or air heat pump, it is also active in the protection of the natural environment, as all types of heat pumps are based on renewable energy sources. Their work does not cause air pollution, as no harmful substances, including carbon dioxide, are emissions.
Ground heat pumps, as well as air heat pumps, are profitable for investors because they realistically reduce heating costs. They can also be combined with a photovoltaic installation providing free electricity necessary for the operation of a heat pump, which will make the operation of the heat pump completely cost-free.
Heat pumps are safe, maintenance-free, convenient and reliable devices. They can provide high thermal comfort for many years – it is estimated that even for 50 years.
When faced with a ground pump or an air pump, many important factors should be taken into account. First of all, the main difference will be visible in the costs – investment in ground heat pumps is associated with the need to incur much higher initial expenses, which results from the need to install horizontal collectors or vertical collectors. Air pumps are also easier to install than ground pumps, and their small size means that they can be installed practically anywhere.
The operation of air and ground heat pumps is also based on a different heat source. Air pumps operate in changing conditions – in winter temperatures drop to as much as -20 degrees Celsius, while in spring and summer the pump works at about + 10-15 degrees. The ground is a much more stable source of heat – the temperature underground does not hesitate there – the difference is from a few to several degrees, even in the case of severe frosts. That is why ground heat pumps can be devices with high efficiency.
In the case of air heat pumps, there has been a change in performance in the last few years. Technological progress has made them work efficiently even at -25 degrees Celsius.
If you do not know whether to opt for a ground or air heat pump, consult experts – Hymon specialists will help you choose the best solution for your home!
The installation of a heat pump is an effective way to ensure thermal comfort at home with low operating costs of the device. Heat pumps are energy-saving heating systems, convenient to use, safe and reliable. However, electricity is necessary for their operation, so many investors, before deciding to buy a heat pump, wonder how much electricity is consumed by a heat pump and how the consumption of electricity by a heat pump affects the amount of electricity bills?
The growing ecological awareness of the society translates into a growing interest in renewable energy installations, i.e. based on renewable energy sources. One such solution is heat pumps. These are innovative and ecological heating systems that use thermal energy accumulated in the ground, water or in the air, and therefore in completely natural and inexhaustible resources. In addition, during the operation of the heat pump, no harmful, polluting the natural substances are emitted.
The last few years have also been a systematic increase in the prices of fuel fuels. In order to ensure independence from them and incur less heating expenses, many investors began to see heat pumps as a way to achieve savings.
For its operation, a heat pump needs electricity in a small amount – only 25% of its operation depends on the electricity supply, and 75% bases its work on natural resources. How much electricity does a heat pump consume? It depends on several factors: the conditions in which the heat pump operates, the location of buildings, the number of inhabitants and their lifestyle, the insulation of the building, its ventilation, the amount of water needed, water temperature, as well as the heating system (underfloor heating or traditional heaters).
In order to reduce how much electricity the air heat pump will consume, the heat demand should be divided by the average annual heat factor. The formula for the estimated electricity consumption of the air heat pump is as follows:
Heat pump current consumption = Heat demand / Average annual heat pump efficiency factor
What is the COP Efficiency Factor? This is one of the key technical parameters of heat pumps. It determines how much thermal energy the heat pump will give in relation to 1 kWh of electricity consumed. This parameter is determined by heat pump manufacturers. For users, the higher the COP, the better, because with the same amount of electricity, the pump can generate more heat.
Electricity consumption by the heat pump is also associated with the so-called device efficiency class. The desired value of the efficiency class is within 3.5-5.5. This means that the heat pump gives 3.5 – 5.5 kWh of heat energy to the heating system after 1 kWh of electricity is consumed.
Investing in a heat pump is economically profitable mainly because it bases its operation mainly on natural, and therefore also free, energy resources. For operation, a heat pump only needs 25% of electricity supply.
Heating with a heat pump, unlike heating with other heating systems, is much cheaper. Estimated average annual cost of heating with a house heat pump with an area of 150m2 It is about 1-1.5 thousand. PLN, while the consolidation gas stove is 3-3.5 thousand. annually. The heat pump is currently the cheapest heating system, and additionally provides a very quick return on investment, after just a few years.
When choosing a heat pump, it is worth following the technical parameters it has. The higher the COP coefficient, and therefore the amount of heat produced to heat the house and prepare domestic hot water in relation to the amount of electricity consumed, the less electricity will be used. This will translate into lower electricity bills for many years, as the heat pump may have up to 50 years of service life. In addition, no other device will ensure such independence from increases in fuel prices as an air heat pump.
Energy consumption can be covered by the operation of a photovoltaic installation that provides free electricity. Thus, the heat pump will become a cost-free device, and the electricity bills related to the operation of the heat pump will decrease to zero.
