Get a condensing gas combination boiler to save on heating costs
Your gas costs seem to cost more each year as the worldwide demand for gas increases. If you use gas central heating your gas fired boiler is a large user gas and large proportion of your gas bill. You could trim your gas costs by up to 35% if you instal a new gas-saving condensing combi boiler.
Operating in the background your current boiler will be heating your home and offering hot water for washing cutlery and clothing in addition to powering your bath. Boilers have a lifetime of 15 years. New and replacement boilers will be much more cost-effective than your current boiler. You can evaluate the relative efficiency of boilers by looking at their SEDBUK evaluation, SEDBUK A grading is the most economic at 95% efficiency in pulling heat from the gas consumed.
You need to deliberate whether it is economic to proceed with your older boiler as it reaches the end of its life rather than changing to a new replacement boiler and enjoying the increased gas efficiency. You can cut your gas bills significantly if you invest in a new energy efficient boiler. If you do replace your boiler you could study a combi boiler which is ideally suited for the smaller home or houses where there are a limited number of people in the home. A gas combi-boiler takes cold water from the mains and heats it as called for thereby doing away with any demand for the hot water storage tank. If you have a combi-boiler you will find that hot water may not be available in the kitchen if you are filling a hot bathtub as it heats the hot water as needed.
Other heating boiler types use a hot water cylinder to store hot water so that it is accessible in larger quantities later in the day. Even though there hot water cylinder may be lagged it will lose heat leading to inefficiencies in the heating system. The tank also requires storage space although large volumes of hot water are available for several baths in a short space of time.
eradicating the storage cylinder by installing a combination boiler means that your central heating system will be up to 60% more efficient. Another form of the 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. Clever use of this energy to heat the water on demand means that this type of boiler can further save on your heating costs.
