Why condensing combi boilers are cost-efficient
It seems that every month energy prices are going up resulting in higher energy bills. One major consumer of gas in the home is the heating boiler. You could save up to 30 percent on your current gas bills by installing a condensing combi boiler.
Your current gas boiler delivers your hot water and central heating. After 15 years your boiler will have passed its useful life-time and start to become ineffective. As boiler technology advances current examples are more cost-efficient than those installed in older homes.
You need to deliberate whether it is economic to continue with your aging boiler as it reaches the end of its life rather than swapping to a new replacement boiler and enjoying the increased energy efficiency. You can cut your energy bills significantly if you invest in a new gas efficient boiler. The most well-known boiler type is a condensing 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 draws water through the mains and heats it on call for, doing away with the need for a storage cylinder. If you have a gas combination boiler you will find that hot water may not be ready in the kitchen if you are filling a hot bath as it heats the hot water as needed.
Other gas fired boiler types use a hot water cylinder to store hot water so that it is accessible in larger measures later in the day. The hot water cylinder is a major source of heat loss in the system leading to waste. In addition the hot water cylinder takes up space in the household which could be used for other storage uses.
You can get efficiencies of up to 60 percent by putting in a combi boiler and getting rid of the hot water storage tank. A combi condensing boiler is even more economic than a common combination boiler as it extracts heat from the hot flue gases and uses it to heat water. The gas requirements of the boiler are significantly reduced as it reuses the exhaust gases heat.
