The new Sirius three range of wall-hung and floor-standing stainless steel boilers from Potterton Commercial offers an extended range of outputs, improved aesthetics, simple-to-use yet advanced controls and a five-year warranty for complete peace of mind. 

The range features 15 outputs, from 50-150kW in the wall-hung range and 50-250kW in the floor-standing range. A key feature of the 130 and 150kW models is their footprint is the same as the 110kW making them easier to position when space is a premium. All the boilers have been designed to fit through 700mm doors.

With seasonal efficiency up to 97.5%, the boilers modulate up to 9:1, intelligently using the right amount of fuel to meet the set central heating temperatures. The ultra-low NOx, under 24.7mg/kW, is one of the lowest on the market. The upgraded Siemens controls can be programmed to work with solar thermal, biomass and buffer tanks, offering greater efficiency.
