Typically more than half the money spent by households on fuel bills goes towards space and water heating. In order to minimise bills it is important to choose the most appropriate and efficient heating system.
Mains gas is typically the cheapest fuel for heating a home, but you can make significant reductions in your gas bill by replacing an old inefficient boiler. A modern condensing boiler is about 90% efficient. This makes them typically at least 25% more efficient than an old non-condensing gas boiler. There are regular boilers which are combined with cylinder for storing hot water and combination (or combi) boilers which have not hot water cylinder. Not all properties have access to mains gas. If you are relying on LPG or oil for your boiler, there might be better alternatives, such as a biomass boiler or heat pump.
Ways to improve your heating system
- Heating controls – improved heating controls can help ensure you only provide heat where and when you want it. A room thermostat helps you maintain you home at an appropriate temperature, preventing it getting warmer than necessary. Electronic Thermostatic Radiator Valves (eTRVs) can allow you to set different programs for each room, helping you avoid heating a room at times when it is not used.
- Radiator reflector panels can help you limit the heat lost from radiators attached to external walls
- Bleeding radiators – releasing any trapped air in the radiator enables hot water to fill the whole radiator
- Flushing your central heating system – a combination of sludge and rust will build up in a central heating system over time. This can be cleaned out by a power flush and the process will improve the efficiency of the system.
- Keeping your central heating system clean – using a chemical inhibitor can decrease the rate of corrosion in the system. A Magnaclean filter can attract any rust from the water flowing into the boiler.
