Save gas with a combi
Save gas with a combi
It appears that every month gas prices are increasing resulting in higher gas bills. If you use gas central heating your gas boiler is a large user gas and large proportion of your gas bill. Installing a modern condensing combination boiler could save you one third on your gas costs.
Your current gas boiler provides your hot water and central heating. Boilers have a life-time of 15 years. New and replacement boilers will be much more efficient than your current boiler. The SEDBUK evaluation gives an indication of the efficiency of a gas fired boiler with A being very cost-effective and G being very wasteful.
Exchanging an older central heating boiler could save you in the long run through the accumulated efficiency you will receive. You can cut your gas bills significantly if you invest in a new energy efficient boiler. 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 called for thereby eradicating any requirement for the hot water storage tank. Having instantaneous hot water is a benefit but, depending upon the the power rating of your gas fired boiler, you may find that the central heating boiler is not able to supply multiple hot taps at the same time.
A typical gas boiler will use a hot water tank to store hot water it develops during the daytime. The hot water cylinder is a major source of heat loss in the system leading to inefficiencies. A disadvantage of using any hot water storage cylinder is that it will need space in your house although it does mean that you can access to great amounts of hot water whenever required.
60 % heating efficiencies are accessible to you by swapping to a gas combi-boiler which will heat water on demand and not require the inefficient hot water storage tank. The standard combination boiler does lose gas through the hot exhaust gases. This can be taken by a condensing combi-boiler which is even more cost-efficient. The energy demands of the boiler are significantly cut as it reuses the flue gases heat.
