Power HT+

High output gas condensing systems
Power HT+

High output gas condensing systems

Single or cascade centralized heating systems installations

Commercial

Floor standing

The range of Power HT+ consists of floor-standing commercial condensing boilers, with output between 50 and 250 kW (50/30°C).

Power HT+ 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, up to 6 boilers.

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