Heat pumps designed by calculation, not guesswork
A heat pump is a refrigeration circuit working in reverse. We work with these circuits every day — so we know where the design mistakes are made that you then pay for on every monthly bill.

Air-to-water heat pump
Connects to existing radiators or underfloor heating and replaces the boiler. Suitable where the whole building needs heating as well as hot water. We choose the output based on the calculated heat loss and the coldest days in the area — not on square metres.
Air-to-air heat pump
Heats the space directly through indoor units, and the same unit provides cooling in summer. Installation is simpler, with no changes to the water pipework, which makes it a common choice for shops, workshops, offices and supplementary heating in halls.
Calculation and design
Before choosing a unit, you need to know how much heat the building loses. An oversized heat pump switches on and off in short cycles, which shortens the life of the compressor; an undersized one has to top up with an electric heater, and your bill goes up. Design is the part of the job that determines the result.
Servicing and inspection
Annual inspection of the refrigerant circuit, pressures, heat exchangers and controls. For units containing more than the specified amount of refrigerant, we also carry out the mandatory leak check under the F-gas Regulation, including the records.
The three most costly mistakes
Output based on guesswork
Without a heat loss calculation, choosing a unit is a lottery — and you lose every month.
A badly positioned outdoor unit
A unit that draws in its own cold exhaust air, or makes noise under a neighbour’s window, is difficult to fix after the fact.
Controls left unadjusted
A correctly set weather compensation curve has a greater effect on energy consumption than the brand of the unit.
Heat pumps — frequently asked questions
Which heat pump is right for my building?
It depends on the building’s heat loss and on how it is heated today. An air-to-water heat pump connects to existing radiators or underfloor heating and replaces the boiler. An air-to-air heat pump heats the space directly and is simpler to install, but it does not heat water. Without a heat loss calculation, any recommendation is only an estimate.
Does a heat pump work in freezing temperatures?
Yes, but less efficiently — the colder it is outside, the more electricity it uses to produce the same amount of heat. That is why the design takes into account the coldest days in the area, and the output and any backup (bivalent) heat source are chosen accordingly. In the Kysuce region, this matters more than in the south of Slovakia.
Can a heat pump also be used for cooling?
Yes, most units can reverse their operation and cool the space in summer. With underfloor heating, cooling is limited by the dew point; with fan coil units or indoor units, it works as fully fledged air conditioning.
How often does a heat pump need servicing?
Once a year — a check of the refrigerant circuit, pressures, heat exchangers, circulation pump and control settings. Units containing more than a certain amount of refrigerant also require a mandatory leak check under the F-gas Regulation, along with record-keeping.
Why buy a heat pump from a refrigeration company?
A heat pump is a refrigeration circuit working in reverse — the compressor, evaporator, condenser, expansion valve and refrigerant are the same. Anyone who works with industrial refrigeration every day knows this circuit more thoroughly than a heating installer who only sees it during installation.
