It seems that each month gas prices are increasing resulting in higher heating bills. If you use gas central heating your boiler is a large user gas and large proportion of your gas bill. You could cut your gas costs by up to 35% if you instal a new gas-saving condensing combi boiler.
The central heating gas boiler heats water for both washing items and heating the radiators. Your current boiler will have an anticipated life off up to fifteen years. If your boiler is nearing the end of its lifetime it could be very uneconomical in comparison to younger models. You can evaluate the comparative efficiency of boilers by looking at their SEDBUK evaluation, SEDBUK A ranking is the most economical at 95% efficiency in pulling heat from the gas consumed.
Observing that this it could be cost effective to exchange your boiler if your current model is nearing the end of its life-time. A new central heating boiler should lead to a large reduction in your gas heating bills. If you have a smaller home with a intermediate need for hot water a combi boiler is probably the best option for you. Your hot water storage cylinder becomes redundant with a gas combi-boiler which heats water on need. If you have a combination boiler you will find that hot water may not be ready in the kitchen if you are filling a hot bath as it heats the hot water as required.
A average boiler will use a hot water cylinder to store hot water it develops during the day. This is the most inefficient method and the heat losses are great even with a fully lagged tank. If you have a smaller household you will find that you could have other uses for the space that the hot water tank takes up.
getting rid of the storage cylinder by installing a combi boiler means that your central heating system will be up to 60% more efficient. Another variant of the combination boiler is the combi condensing boiler which is able to extract waste heat from the flue gases and use this to heat water when necessary. Taking saved heat back into the hot water heating process significantly trims the requirement for gas use and will lead to a further step-down in your heating bills.
