These sophisticated devices replace completely conventional heating systems (e.g. boilers, oil, gas, electric, etc.) and in addition they produce summer cooling, eliminating thereby intensive air conditioning units. This is achieved by exploiting the energy offered by the environment which is utilized by heat pumps for heating and cooling room (residence rooms, working rooms, industrial spaces etc).
Heat pumps can be combined very effectively with systems that perform in low temperatures such as underfloor heating, fan coils ... when combined with conventional type radiation bodies (panels, slices ...) should the radiators be over-dimensioned to operate at lower temperatures. Nevertheless there are heat pumps of high temperatures that may be combined with existing radiators without being over-dimensioned.
In the case of cooling heat pump can be combined with underfloor heating and air conditioning units (fan coils) but not with radiation heating elements (panels, slices), cause thus we will have on their surface side condensations.
