Gas combination boiler efficiencies
Gas combination boiler efficiencies
Energy costs are rising around the globe and it appears that gas costs cost more every year. To combat this we need to go over our use of gas in the home. You could save up to 30 percent on your latest heating bills by installing a condensing combi boiler.
Your existing heating boiler has to work hard delivering hot water to your taps and heating water for your central heating. Your current boiler will have an anticipated life off up to fifteen years. Although your boiler at home may only be 10 or 12 years old it could be wasting gas. Many older boilers are rated as a G on the SEDBUK scale, where A is the most efficient at 95-98% and G the least efficient boiler at 20-30%.
You need to consider whether it is cost-efficient to proceed with your older gas boiler as it reaches the end of its life-time rather than swapping to a new replacement boiler and savoring the increased energy efficiency. A new condensing combi-boiler could cut your costs significantly. If you do replace your boiler you could consider a gas combination boiler which is ideally suited for the smaller home or properties where there are a limited number of people in the home. A gas combi-boiler draws water through the mains and heats it on demand, doing away with the need for a storage tank. The slight drawback with instantaneous hot water is that there is a limited capacity meaning that large households may not be able to run several baths or showers at the same time.
A typical gas boiler will use a hot water tank to store hot water it produces during the daytime. Even though there hot water cylinder may be lagged it will lose warmth leading to waste in the heating system. A drawback of using any hot water storage tank is that it will require space in your house although it does mean that you can access to great amounts of hot water whenever called for.
60 % heating efficiencies are accessible to you by shifting to a combi-boiler which will heat water on need and not require the inefficient hot water storage tank. A combi condensing boiler is even more cost-efficient than a regular combi-boiler as it extracts heat from the hot exhaust gases and uses it to heat water. Clever use of this gas to heat the water on need means that this type of gas fired boiler can further save on your gas heating bills.
