Air to Water Heat Pumps
Air to water heat pumps produce hot or chilled water that a building distributes through radiators, fan coils or radiant floor circuits, and in some listings also supplies domestic hot water. This page gathers the water-system models together.

Water temperature and flow figures are not listed for these models on this site, and no such figure is promised here.
How a water system changes the buying question
With a direct air system, the buyer asks about room units and airflow. With a water system, the buyer asks about the existing or planned distribution: radiators sized for a given water temperature, an underfloor circuit with its own temperature limits, or a domestic hot water cylinder that needs a certain recovery behaviour. The listings on this site do not state water temperatures or flow rates, so a buyer planning a retrofit should send the distribution details in the inquiry — radiator sizes, floor construction, cylinder size — and let the reply confirm whether a listed model matches. That is a better order than choosing a kilowatt figure first and discovering the distribution mismatch later.
The three detailed models
The Deluxe monobloc single-phase model covers 4–16 kW with a model range from KATWHP-4KWR290M1N to KATWHP-16KWR290M1N at 220–240 V and 50 Hz. The Deluxe monobloc three-phase model covers 12 kW and 16 kW with models KATWHP-12KWR290M3N to KATWHP-16KWR290M3N at 380–415 V, three-phase, 50 Hz. The Aeolus split model covers 6–20 kW and is described for heating, cooling and domestic hot water, for residential and small commercial buildings, and for the European market. Each detail page states exactly which of those facts are listed parameters and which are description facts, so the buyer can see the evidence level at a glance.
