Save energy with a combi
Save energy with a combi
It seems that every month gas prices are increasing resulting in higher gas costs. One way of reducing heating costs is to survey how you are wasting gas in the home. You could save up to one third on your latest heating bills by putting in a condensing gas combi-boiler.
A central heating boiler needs to be able to provide adequate hot water to heat your house and furnish hot water for washing. Your current central heating boiler will have an expected life off up to 15 years. Although your boiler at home may only be 10 or twelve years old it could be wasting energy. You can evaluate the comparative efficiency of boilers by looking at their SEDBUK grading, SEDBUK A grading is the most cost-effective at 95% efficiency in pulling heat from the gas consumed.
You need to consider whether it is economic to continue with your older heating boiler as it reaches the end of its lifetime rather than switching to a new replacement boiler and savoring the increased gas efficiency. This can reduce your fuel costs down considerably. A combination boiler is the most widely known type of boiler, and is good for small homes with few people, or people who don’t want to wait for their hot water. A gas combi boiler draws water through the mains and heats it on need, doing away with the need for a storage cylinder. If you have a combination 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 amounts later in the day. The hot water cylinder is a major source of heat loss in the system leading to waste. A drawback 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 larger amounts of hot water whenever needed.
eradicating the storage cylinder by installing a combi boiler means that your central heating system will be up to 60% more efficient. A combi condensing boiler is more cost-effective than a standard combi-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 energy savings.
