What type of heat pump to choose? – PART 1


Winter is knocking on the door and I started my heat pump again. Since last post one idea occurred to me and that is answering quite frequent question: What type of heat pump to chose. I prepared relatively simple decision making model for choosing a heat pump for heating the house during the winter. Everybody knows that we have several types of heat pumps multiplied by number of producers and you can get 1000 of different heat pumps … O.K. it is not so bad :-) … actually we have few types of heat pump to choose between – in general: air to air heat pump, air to water heat pump, ground sourced heat pump (water to water). To be able to choose the right one you must consider: type of heating to be used, current/new building conditions, available heat sources, legislation, building restrictions, climate, heat losses, preparing also hot water, heating regime (low or high temperatures), and financial part.



In general one could say – every heat pump is better than no heat pump. But let us check in details in PART 2 … coming soon.

By the way, my heat pump is operating during the summer only 20 minutes per day for hot water (300 liters of hot water).

Detailed installation Schema for Geothermal Heat Pump Project


After receiving few questions about installing heat pump, connecting to the heating system and to the water heater, I decided to publish detailed installation schema. Here you can see every valve, pump, pipes, heat pump, water heater and other parts needed to operate the heat pump.


On the upper left corner of the schema you can see the legend for better understanding of the schema. I hope I didn’t forget anything – I cannot guarantee :-)


Electrical part of schema is missing (wiring) because I’m still working on it. Hope I will finish and publish it soon.If somebody finds an error in the schema please add a comment to this post. I case somebody have further question … please do not hesitate to post your comment.
