Boilers can produce as much as 60% of all domestic CO², so consequently the Part L Building Regulations now state that practically all new and replaced boilers should have a SEDBUK rating of A or B.SEDBUK is the acronym for Seasonal Efficiency of Domestic Boilers in the UK. The rating it gives is an expression of its effectiveness in converting fuel into heat. A boilers are 90% or above efficient, while B boilers offer 86% or more. The rating runs from A to G, but only A and B carry the energy saving recommended logo.

High efficiency condensing boilers fall into these categories, as they convert 88% or more of their fuel into heat. With good heating controls, your fuel bill can be reduced by 40%. Heating controls allow for effective management of your boiler use so that you can create different heat in different rooms and set a heating timer.

Conventional boiler designs lose heat energy with the products of combustion. It causes convection to emit the exhaust through a flue, but is otherwise wasted energy. Condensing boilers contain a heat exchanger that pre-heats water in the boiler. Water vapour is produced that condenses back into liquid form and releases latent heat. Effectively, in a high efficiency boiler, the heat produced during combustion is largely absorbed by the heat exchanger into the heating water with little wastage and less fuel used.


A high efficiency condensing boiler will cost in the region of £600 – £1000.
