How to Reduce Your Heating Bills

How to Reduce Your Heating Bills

Why change your inefficient old boiler?

The table outlines why:

£634 Detached
£458 Terrace
£393 Bungalow
£308 Flat

Other important factors in efficiency are room thermostats, TRVs on radiators and programmable thermostats. They all contribute towards lowering your heating costs. Here at ‘All Things Gas’ (ATG) such devices can be fitted for as little as £80 (parts and labour)!

Here’s for the Scientific/Regulations bit…

When older boilers are replaced, the advances in boiler technology mean that substantial efficiency improvement can be expected from newer equipment. Manufacturers now design for maximum efficiency consistent with durability.

The greatest energy efficiency benefits are obtained from installing condensing boilers, these are always more efficient then non-condensing models. In England and Wales it is a requirement of the building regulations since 1st April 2005 that newly installed gas boilers should be condensing, with a Seasonal Efficiency of a Domestic Boiler in the UK (SEDBUK) efficiency of 86% or more.

Why are condensing boilers more efficient?

A condensing boiler has a large heat exchanger which extracts more heat from the flue gases, In a non-condensing boiler, the flue gases are at a temperature of 120-200 C. In a condensing boiler, more heat is removed and the temperature falls to below 100 C and as low as 50 C for the most efficient boilers operating at reduced boiler return temperature. The water vapour in the gases condenses (hence the name condensing boiler) and the resulting liquid has to be drained away. As the heat exchanger gets wet in the process, it is more susceptible to corrosion. To avoid this, it has to be constructed from corrosion-resistant materials, i.e. stainless steel.
