Why condensing combi boilers are cost-effective
Energy costs are up around the globe and it appears that gas bills cost more every year. One way of pruning heating costs is to review how you are wasting energy in the home. Installing a modern condensing gas combi-boiler could save you 30 percent on your gas costs.
The central heating gas boiler heats water for both washing items and warming the radiators. After fifteen years your boiler will have passed its useful lifetime and start to become ineffective. New and replacement boilers will be much more economic than your present-day gas fired boiler.
If your boiler is over ten years old, it might be worth investing in a fresh model. A new condensing combi boiler could cut your bills significantly. If you have a smaller home with a reasonable call for for hot water a gas combination boiler is probably the best option for you. A gas combination boiler takes cold water from the mains and heats it as necessary thereby doing away with any requirement for the hot water storage cylinder. Hot water is immediate but if someone runs a hot tap while you’re taking a hot shower you may find that your hot bath becomes colder.
A normal central heating boiler heats the water and channels it to a storage cylinder for instant access. This is the most ineffective method and the heat losses are great even with a fully lagged cylinder. If you have a smaller household you will find that you could have other uses for the place that the hot water tank takes up.
60 percent heating efficiencies are available to you by swapping to a gas combi boiler which will heat water on call for and not require the inefficient hot water storage cylinder. A combi condensing boiler is even better where water is heated on demand and the hot flue gases normally vented to the air is used to heat a secondary coil. Using the reclaimed heat to create hot water leads to additional gas savings.
