Efficient combi-boilers
Energy prices are growing around the world and it seems that energy costs cost more every year. To combat this we need to review our use of energy in the home. Installing a modern condensing gas combination boiler could save you 30 percent on your energy costs.
A central heating gas fired boiler needs to be able to deliver sufficient hot water to heat your home and furnish hot water for laundry. After 15 years your gas boiler will have passed its useful life-time and start to become ineffective. Even though your present-day gas fired boiler may be running correctly it could be inefficient in comparison to the modern one. The SEDBUK evaluation gives an indication of the efficiency of a boiler with A being very efficient and G being very uneconomical.
If your central heating boiler is over ten years old, it might be worth investing in a fresh model. You can cut your gas costs significantly if you invest in a new gas efficient boiler. If you have a smaller home with a intermediate need for hot water a gas combi boiler is probably the best option for you. Your hot water storage cylinder becomes redundant with a gas combination boiler which heats water on need. The slight drawback with immediate hot water is that there is a limited throughput meaning that big households may not be able to run multiple baths or showers at the same time.
If you have a system or regular gas fired boiler it will use a hot water tank to save hot water created earlier for use when required later that day. This is the most uneconomical method and the heat losses are great even with a fully lagged cylinder. Whilst storing the water means that great amounts of hot water are available from the cylinder it will take up valuable space in your home.
A gas combi-boiler is a type of gas fired boiler where the water is heated on call for and is 60percent more efficient than the indirect hot water storage method. A combi condensing boiler is even better where water is heated on call for and the hot flue gases normally vented to the air is used to heat a secondary coil. The energy requirements of the boiler are significantly reduced as it reuses the flue gases warmth.
