The small gas boiler THERM PRO 14 XZ.A can heat water in an external reservoir and in water-heat systems it works in the same way as heating only boilers. The external reservoir is heated by an integrated three-way valve that is part of the wall boiler. Two types of the boiler are available according to the type of fuel, i.e. boiler combustion natural gas or propane.

The boiler is for heating of buildings with a heat loss up to 14.0 kW. When developing and manufacturing the emphasis was on maximum efficiency and minimum emissions into the air. With its wide range of types and reservoir volumes this boiler can produce relatively high amounts of hot water to satisfy both usual households as well as demanding clients requiring high comfort.
