Combi boilers reduce gas costs
Combi boilers reduce gas costs
As the world evolves there is going up call for for gas and prices are increasing each year. If you use gas central heating your heating boiler is a large user gas and large proportion of your energy bill. You could cut your gas costs by up to 35% if you fit a new energy-saving condensing gas combi-boiler.
A central heating boiler needs to be able to deliver sufficient hot water to heat your home and furnish hot water for laundry. Boilers have a life of 15 years. As boiler technology improves current examples are more economical than those installed in older homes. The SEDBUK evaluation gives an indication of the efficiency of a gas boiler with A being very efficient and G being very wasteful.
You need to deliberate whether it is cost-efficient to proceed with your older boiler as it reaches the end of its life-time rather than swapping to a new replacement boiler and enjoying the increased energy efficiency. This can cut your fuel costs down considerably. If you do replace your boiler you could consider a gas combi-boiler which is ideally suited for the smaller home or properties where there are a limited number of people in the home. A combination boiler takes cold water from the mains and heats it as required thereby doing away with any requirement for the hot water storage tank. Although the boiler can deliver immediate hot water it will have a limited capacity and will not be able to service multiple hot taps at the same time.
Other gas fired boiler types use a hot water tank to store hot water so that it is accessible in larger measures later in the day. This is the most uneconomical method and the heat losses are great even with a fully lagged cylinder. If you have a smaller home you will find that you could have other uses for the space that the hot water tank takes up.
You can get efficiencies of up to 60 % by putting in a combination boiler and getting rid of the hot water storage tank. A combi condensing boiler is even more economic than a common combi-boiler as it extracts heat from the hot flue gases and uses it to heat water. Using the reclaimed heat to create hot water leads to additional energy savings.
