Boilers account for around 60% of the carbon dioxide emissions in a gas heated home. By fitting a new high efficiency condensing boiler with full heating controls, you will significantly cut your home's carbon dioxide emissions and could save up to £270 a year. As current boilers have a life span of around 15 years, choosing a heating system with a high efficiency condensing boiler incorporating the correct heating controls can make a huge difference to your heating bills. A high efficiency condensing boiler works on the principle of recovering as much of the "normally wasted heat" as possible which is usually lost through the flue of a conventional (non-condensing) boiler.
The best high efficiency condensing boilers convert more than 90% of their fuel into heat, compared to, at best 78% for conventional types. If your boiler is an A-rated boiler according to SEDBUK ratings then it is a high efficiency condensing boiler. Correctly fitted heating controls will keep your home at a comfortable temperature, making it warm when you want it but switching off when you don't.
Controls include but are not limited to: room thermostat, digital programmer, zone valves, programmable or time delayed devices, cylinder thermostat and thermostatic radiator valves (TRV's), differential temperature sensors and heat source switching.
