Brent Witherspoon - Chelmer Heating’s MD was one of the first people in the UK to fit a Condensing Boiler in the mid 80’s, since then, these highly efficient boilers have now become a legislative requirement. Condensing boilers are designed to recapture energy from the flue gas exhaust but only work efficiently when the return temperature is below 50°. Our Thermocat cylinder has been specifically designed to keep a condensing boiler in condensing mode for up to 95% of the time which reduces both your fuel bill and carbon footprint.

• produce less carbon dioxide while still meeting heating needs.
• reduce the amount of heat that is lost through the flue, compared with ordinary boilers.
• convert 86 per cent or more of the fuel they use into useful heat (older types of ordinary boilers may convert as little as 60 per cent of fuel to useful heat).
• save money on your heating bills
• help to tackle climate change
