House heating with heat pump

A heat pump is an effective way to heat a house at a relatively low cost. Its operation is similar to that of a refrigerator, just like a… The other way around.
The basis is to obtain heat energy from external sources – water, earth and air, accumulate it and then transfer it to the heating system of the building. It is electrically powered. Cooling gas (commonly known as “freon”) flows in a closed circuit. When it is subjected to high pressure by means of a compressor, it changes its state of concentration to liquid and releases heat to the environment. As it expands and returns to a volatile form, it draws heat from the outside. The mechanism only consists of compressing the gas inside the building and heating up the domestic water in the installed tank.
The most popular sources used by the pump are:
The most common sources used by the pump are: atmospheric air, inflatable to the heat exchanger,
soil – the heat exchanger is buried about 1.5 m below the ground surface and filled with an antifreeze mixture of glycol and water,
water – the exchanger is placed at the bottom of a pond or river or admitted into the ground intake.
Providing 2-5 kWh of energy, the pump requires only 1 kWh of power – it gives more energy than it needs to operate.
Proper programming of the heat pump allows for significant savings. You can set its operation so that it consumes electricity and accumulates heat during the hours of cheaper, night-time tariff. Then, during the day, it will switch on only temporarily to heat the room to a certain level. In addition to programming, the pump operates unmanned, equipped with a thermostat automatically regulates the temperature of the interior.
The pump should be installed in the so-called technical room – it is large in size, and in addition, you need to insert next to it a domestic water tank and a heat buffer. Not without significance is also the noise during work, which for convenience is good to suppress.
Assuming a working time of about 1500 hours per year, its life span will be 50 years. When designing a heating system for a dream home, it is worth considering this ecological and economic investment.
