These two machines seemingly distinct, are merged in the same section because they have the same principle of operation, or that of the heat pump. The main difference is the power, where in the conditioner is lower and the heat pump is increased.
In fact, the air conditioner is mainly used to cool a room by blowing air cold and in some occasions it can act as a support for the heating system existing. Only in very small rooms it can act as a heating system.
The heat pump is a heating system that can be replaced to a classic boiler. With simple interventions on the plant can provide you can use hot water and, if required, also a cooling of the entire building.
The principle of operation of the heat pump is similar to that of a refrigerator, but reversed. In fact, in the fridge, to cool down the food, extracting heat from inside and expels it outside.
A heat pump, using the same principle but in reverse: it extracts heat from a natural source outside of the house and carries it inside the building at the required temperature.
All this process is possible thanks to a specific gas, which goes through a cycle, said refrigeration cycle. In this cycle the gas absorbs heat from the temperature external to the property and, as a result of a compression part of an electrical machine which raises the temperature, it transfers heat to the heating system. The energy thus given to the plant is, on average, 4 times greater than that spent by the electric compressor.
All this is translated with a simple example: assuming that I have to enter inside the building, 4kW of heat, through a heat pump I need to spend only 1kW of electricity to get the 4kW that we need.
But the other 3kW from where are taken?
Are taken from the heat that there is on the outside of the house. For this reason, the heat pump is considered a renewable energy source, because it exploits to the 3/4 power coming from the outside, that is free.
For the installation of a heat pump, it is fundamental to the evaluation of its thermal requirements: the optimal operation of a heat pump is generally in new homes, with underfloor heating or low temperature radiators. In the case of the redevelopment of a traditional system, the thermal insulation of the building will have to be performant to contain heat loss and to lower the operating temperature of the radiators the existing. Not only that, but today there are additional technologies that allow also the efficient installation in existing buildings.

In the last it is good to specify the range of operation of the heat pump according to the outside temperatures.
Now as you may have guessed, in the case of heating, the more the outside temperature is high, the more heat the machine will be able to bring inside of the building. Therefore, the performance of the heat pump are closely related to the temperature.
With temperatures below -5 degrees begin to have made little efficient comparable to those of a classical boiler.
Under -20 degrees instead of the heat pump begins to suffer and may detect some problems of operation.
Compliance with these simple parameters it will be possible to permanently delete the bill from the cng or lpg and save considerably on heating costs.
