Gas and Electric heating in homes is always presumed to be less efficiency than the Central Combi Boiler heating systems, this is incorrect, dependant on your own home lifestyle. Take for example a standard 3 bedroom house with the usual Husband, Wife and 2.4 Children, the homes upstairs is used for only 34% of the day as most are in work/school or other activities outside of the upstairs of the house. Now narrowing this down, over 60% of home usage is the Kitchen and Living room, because of this it is not very efficient to burn gas to heat every room on the home if the Living room and Kitchen are the most used during those periods.
The most efficient way of heating your home it to use the Combi central heating to produce a back ground heating source to provide a minimal temperature in the home (Usually around 16 degrees Celsius). As you go into each of these rooms, you should rely on another heating source to boost the heat to the required temperature as needed. This system has been promoted massively recently by British Gas and the UK Energy Saving Trust in Advertising lowering your combi by just 1 degree. Reducing your room temperature by 1°C could cut your heating bills by up to 10 percent and typically saves around £55 per year. If you have a programmer, set your heating and hot water to come on only when required rather than all the time.
This is also much better in providing quicker heating to the room in need of it, if you up the temperature of the boiler it will take upto an hour for the overall temperature in the whole house to rise to the requested degree. While instead of heating and wasting the heat in the whole home, you just turned on the fire in the living room, this would heat up within around 15mins in the average sized home and not waste heat in other rooms which weren’t being used.
