Power HT-A

High output gas condensing systems
Power HT-A

High output gas condensing systems

Single or cascade centralized heating systems installations

Commercial

Floor standing

The range of Power HT-A consists of floor-standing commercial condensing boilers, with output between 121 and 651 kW (50/30°C).

Power HT-A are heating only boilers for centralized systems with the possibility to be connected to a domestic hot water tank.

Cascade option for greater heating demand.

(**) Low temperature: return temperature (at boiler inlet) for condensing boilers 30°C, for low temperature boilers 37°C and for other heaters 50°C.
(*) High temperature setting means 60 °C return temperature at boiler inlet and 80 °C flow temperature at boiler outlet.
