Gas combi-boilers save gas
Gas costs are rising around the world and it seems that gas bills cost more each year. If you use gas central heating your gas fired boiler is a large user gas and large proportion of your energy bill. Fortuitously help is at hand, fitting a new replacement condensing combi boiler could lead to a heavy decrease in your energy bills.
Your existing gas fired boiler has to work hard providing hot water to your taps and heating water for your central heating. The normal gas boiler lasts for 15 years before you start to incur unannounced problems and it becomes inefficient. As boiler engineering improves present-day examples are more cost-effective than those installed in older homes. Many older boilers are ranked as a G on the SEDBUK scale, where A is the most economic at 95-98% and G the least cost-effective boiler at 20-30%.
Noting that this it could be cost effective to replace your boiler if your current model is nearing the end of its life-time. An gas efficient combination boiler can lead to a large reduction in your gas bills. The most well-known boiler type is a condensing gas combi-boiler which is well suited to smaller families who don’t need large amounts of hot water in a short space of time. A gas combi boiler takes cold water from the mains and heats it as necessary thereby getting rid of any requirement for the hot water storage cylinder. If you have a gas 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 necessary.
A regular central heating boiler heats the water and channels it to a storage tank for rapid access. Even though there hot water tank may be lagged it will lose warmth leading to inefficiencies in the heating system. In addition the hot water cylinder takes up space in the home which could be used for other storage purposes.
A combi-boiler is a type of gas boiler where the water is heated on call for and is 60% more efficient than the indirect hot water storage method. Another form of the gas 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 called for. Taking reclaimed heat back into the hot water heating process significantly cuts the demand for energy use and will lead to a further reduction in your energy bills.
