As the world grows there is rising call for for gas and prices are increasing each year. One leading consumer of gas in the dwelling house is the boiler. You could save up to 30 percent on your present-day heating bills by putting in a condensing gas combi boiler.
Running in the background your present-day gas boiler will be heating your home and providing hot water for washing cutlery and clothing in addition to powering your bath. A boiler does not last for ever and that the average lifespan will be fifteen years. If your boiler is nearing the end of its lifespan it could be very inefficient in comparison to younger models. Many aging boilers are graded as a G on the SEDBUK scale, where A is the most cost-effective at 95-98% and G the least economical boiler at 20-30%.
Observing that this it could be cost effective to substitute your boiler if your current model is nearing the end of its life. You can cut your gas bills significantly if you invest in a new energy efficient boiler. If you have a small home with a intermediate demand for hot water a combination boiler is probably the best option for you. Your hot water storage cylinder becomes redundant with a gas combination boiler which heats water on demand. Having instantaneous hot water is an advantage but, depending upon the the power rating of your heating boiler, you may feel that the heating boiler is not able to supply multiple hot taps at the same time.
A normal gas boiler heats the water and transfers it to a storage cylinder for prompt access. This is the most ineffective method and the heat losses are great even with a fully lagged tank. A disadvantage of using any hot water storage cylinder is that it will require space in your house although it does mean that you can access to large amounts of hot water whenever necessary.
60 percent heating efficiencies are accessible to you by shifting to a gas combination boiler which will heat water on need and not require the inefficient hot water storage cylinder. A combi condensing boiler is better where water is heated on call for and the hot flue gases normally vented to the air is used to heat a secondary coil. Clever use of this energy to heat the water on call for means that this type of boiler can further save on your heating costs.
