High performance
The SB range of high performance stainless steel condensing boilers deliver maximum efficiency levels, very low emissions and real cost savings.
Boilers in the range require minimal floor space and benefit from the very latest in heating technology.
Kondens+ heat exchanger
Patented Kondens+ heat exchanger surfaces create optimum conditions for condensing to occur, and there are two return connections for separation of high and low temperature heating circuits.
This improves the efficiency of the overall heating system and allows further energy savings to be made.
Insulation
To ease transportation of the boiler the main block is delivered with the insulation and casing packed separately.
The total insulation of the boiler block increases efficiency by keeping heat losses to a minimum.
