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?
What factors influence the electricity consumption of the heat pump?
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).
How much electricity does a heat pump consume?
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.
Heat pump and the amount of electricity bills
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.
