How a heat pump works - read step by step
|
|
Heat pumps are able to produce more energy than they consume by using the conventional refrigeration cycle to absorb heat from the environment and raise it to a suitable level for heating. |

Bedrock source
|
|
A bedrock heat pump harnesses stored solar energy from the bedrock via a ground collector installed in one or more vertical boreholes, which can be up to 200 meters deep, the energy can then be used to provide space heating and hot water. |

Ground source
|
|
A ground heat pump uses the solar energy stored in the ground surface using a collector loop that is buried in the earth. |

Air source
|
|
With an air/water heat pump there is no need to dig or drill. Instead you take the energy straight from the surrounding air using an air unit. |

Evaporator, Compressor, Condenser, Expansion Valve
|
|
The brine liquid circulates through the evaporator.
Radiator water circulates through the condenser.
Refrigerant circulates in the cooling circuit. |

Hot water production
|
|
When the start sensor for hot water reaches the required start value the three way valve changes direction of the flow into the TWS coil inside the water heater (shown on the movie). The hot water production stops when the control pressostate reaches the breaking pressure. |
