Gas Boiler XL

The XL boiler range utilises the patented OSS Stainless Steel, long life heat exchanger to provide
maximum efficiency for the lifetime of the boiler.
By combining the fully modulating premix burner technology
with the inbuilt electronic modulating pump and energy
management system, the  XL boiler is one of the most
efficient boilers on the market today. With class leading
efficiencies validated by Gastec at 110.3%, XL boilers can
theoretically recover 99.3 pence for £1 of gas used.
The high efficiency of the boiler also greatly reduces the
amount of flue gas emissions ie, CO2 and NOx. The XL boiler
also achieves the maximum BREEAM points for low NOx with
emissions of less the 30mg/kWh across the range.
