A-rated boiler, A-rated savings

Older boilers aren’t built with the same level of technology as modern boilers and can be woefully inefficient as a result. A key difference is ‘condensing’ technology. Modern condensing boilers recover wasted heat and use it to heat your water. This makes them an ultra-efficient way to heat your home – providing extra warmth without the extra cost.

If your boiler was installed before 2005, upgrading to a condensing boiler will increase your efficiency, decrease your carbon footprint and help to lower your monthly energy bill.
