Cost-effective gas combination boilers
Cost-effective gas combination boilers
As the world grows there is going up demand for gas and prices are going up each year. If you use gas central heating your gas boiler is a large user gas and large proportion of your gas bill. You could cut your gas bills by up to 35% if you fit a new gas-saving condensing combi boiler.
The central heating gas boiler heats water for both laundry items and warming the radiators. After 15 years your gas boiler will have run its useful life-time and begin to become ineffective. New and replacement boilers will be much more economic than your present-day central heating boiler. A modern-day gas fired combi boiler can be 95% efficient in its use of gas and ranked A on the SEDBUK scale whereas your present-day gas fired boiler may only be 30% economic.
Substituting an older central heating boiler could save you in the long run through the raised efficiency you will receive. A new condensing gas combi boiler could cut your bills significantly. gas combination boilers are the most common boilers and are best suited to smaller households where there are not multiple simultaneous needs for hot water. A combi-boiler takes cold water from the mains and heats it as needed thereby eradicating any demand for the hot water storage cylinder. Having immediate hot water is a benefit but, depending upon the the power rating of your heating boiler, you may feel that the boiler is not able to supply multiple hot taps at the same time.
A median boiler will use a hot water cylinder to store hot water it develops during the day. The hot water tank is a major source of heat loss in the system leading to waste. The cylinder also requires storage space although significant amounts of hot water are available for several baths in a short space of time.
A combination boiler only heats water when hot water is required and is consequently far more cost-effective than boiler types which use a storage cylinder. A combi condensing boiler is even more cost-effective than a stock gas combination boiler as it extracts heat from the hot exhaust gases and uses it to heat water. Using the recovered heat to create hot water leads to additional gas savings.
