One of the most acceptable options for an apartment is autonomous heating with a heat pump. This technology is completely ecological, autonomous and multifunctional, and the equipment takes up a little more space in the apartment than a regular washing machine. Heat pumps work well in our climatic zone and are especially effective when heating rooms with an area of 100-150 m 2 . All this makes heat pump systems an ideal solution for autonomous heating of an apartment.
Autonomous heating in an apartment – what should be considered?
The heat pump heating system is characterized by ease of installation – qualified craftsmen can install the equipment (including full adjustment) in 2-4 days. When connecting, it is important to consider one point – the power consumption of the pump must be less than the allocated power of the electrical network for the apartment. The allocated power can vary from 3 kW (in panels) to 15 kW in new buildings. This indicator should be clarified with the energy supplier.
Difficulties arise when trying to disconnect from the centralized heat supply. In some cases, this requires the consent of all residents or disconnection from the heating network of the entire building. For arbitrary disconnection from the system, the owner faces a fine and lawsuits.
The apartment has a heat pump – heat without gas, air conditioning and hot water
The high cost of heat pump systems is justified by their multifunctionality. A heat pump with the right power and professional installation can:
- To heat the premises, providing the necessary temperature of the thermal circuit;
- To heat water, which is especially relevant for cities without centralized hot water supply;
- Cool the room – when installing a special indoor unit, the heat pump in the apartment can also work as an air conditioner, maintaining the climate of the room all year round.
Among other advantages of the equipment, it is possible to single out complete independence from gas, which allows you to completely abandon this energy carrier or reduce its consumption. Well, the main advantage of autonomous heating is that the owner regulates the temperature at his discretion, no more sweaters due to cold batteries in January and heating bills in April at +15°.
When installing a complex heat pump system, the buyer can refuse:
- Gas column;
- Air conditioner;
- Auxiliary asheville water heaters and convectors.
How to conduct autonomous heating of an apartment
Heating systems based on a heat pump can be used to heat several rooms of different sizes. In modern panel houses, it is possible to install equipment:
- For an apartment – in this case, the external unit is installed on the outside of the apartment, and the internal unit is placed in the technical room. Does not require the installation of meters or additional communications (if the thermal circuit is already laid).
- For the entrance, a number of external units with heat exchangers are installed on the outside of the house to obtain heat. Indoor units are removed to each apartment. At the same time, the possibility of individual temperature regulation remains. The system will also require a separate electricity and water consumption meter.
- For the whole house – works according to the same principle as the network for the entrance, but the meter is installed for the whole house.
The last option is especially relevant in view of the difficulties with disconnection from the centralized heating network, which were mentioned above.
Is alternative heating profitable and how much do heat pumps for heating in an apartment pay off?
Heat pumps for an apartment are the most economical heating option at the moment. Taking into account the high efficiency and the ratio of the amount of energy consumed to the amount of heat produced, heat pump heating is several orders of magnitude cheaper than gas and half as cheap as centralized heating.
To understand how much a heat pump pays off, you need to make several calculations:
- The heat loss of an apartment in a well-insulated building averages 50 W per m 2 . Therefore, the heat loss of an apartment with an area of 100 m 2 is 5 kW.
- To heat such a room, you need a heat pump with a capacity of 5+1 kW (to provide heating on “peak” days) and another 1-2 kW for heating water. That is, a total of 7-8 kW. The cost of such an installation is on average 6000-8000 dollars.
- To produce 7-8 kW of heat, the pump consumes about 3 kW of electricity per month, which is equal to UAH 3,360/month at the standard electricity tariff as of 2020. When connecting a three-zone meter, costs can be reduced by up to 40%, i.e. up to UAH 1,344/month.
- The cost of centralized heating in Ukraine varies from UAH 28 to UAH 38 per m2 , depending on the region. On average, heating an apartment of 100 m 2 costs UAH 3,300/month.
- During the heating season (6 months), costs with centralized heating will amount to UAH 19,800, while with a heat pump system at a preferential tariff up to UAH 8,000. The savings is 11,800 UAH or 437 dollars.
- Therefore, the payback period of the system will be up to 18 years. It should be taken into account that this figure decreases significantly when heating a larger area, and heat pump systems work for up to 50 years. In addition, the payback period will decrease with the further increase in the cost of energy carriers and utility services, and this trend has been observed for the past several decades and is unlikely to change in the coming years.
Heat pump heating of an apartment: pros and cons
Based on the above, it can be concluded that heat pump heating systems are the optimal solution for apartments with an area of up to 120 m² if there are funds for the purchase and installation of equipment.
Among the main advantages of a heat pump:
- Full autonomy;
- Energy efficiency and economy;
- Small dimensions.
Disadvantages of this equipment:
- High cost is the main disadvantage of such heating. However, the problem can be solved by installing a heat pump for several apartments.
