Energy Conservation
On all of our installations we have energy conservation in mind.
Due to changes in the Building Regulations, Part L specifically, a few changes have to be made when designing and installing a system.
It requires new boilers to have a SEDBUK efficiency of at least 82% if fuelled by natural gas. SEDBUK is the seasonal measure of a boiler installed in a normal property in the UK.
The SEDBUK percentage of the boiler puts it in a certain band, Band A being the most energy efficient, down the least efficient Band G.
The percentage relates to pence per pound of gas, so Band A boilers offer 90p+ of energy from £1 of gas.
Most condensing boilers are in the Band A category. Not only do we fit energy efficient boilers, we also fit a range of other energy saving equipment:
|
Thermostatic radiator valves (TRVs): the valves are set to the required number, which relates to heat, 1 being the lowest, 5 the highest. When the room gets up to the correct temperature the liquid, wax or gas within the TRV expands, closing the valve so the boiler is not heating a room that does not need to be heated, saving energy.
|
|
Room thermostat: fitted in a room without a TRV on the radiator, normally the hallway. This controls the boiler to the whole heating system basically, when the hallway is up to temperature the thermostat electronically switches the boiler off. The thermostat is normally set to around 21°c.
|
|
Motorised valves: used in conjunction with a system boiler and cylinder. Prevents the boiler overworking, the motorised valves are controlled by the cylinder thermostat and room thermostats. They shut off so the boiler does not keep heating water to supply the hot water cylinder and central heating circuit.
|
|
Correct radiator sizing: as mentioned in the heating section, a smaller volume radiator which puts out the same heat as a larger, older, higher volume radiator saves the central heating circuit having a higher amount of water in for the boiler to heat up. Changing older radiators for newer, more efficient radiators can make a big difference.
|
|
|
Boiler control interlock: this is when all devices such as room thermostat, cylinder thermostats and motorised valves are connected electronically into one wiring centre. It is designed to ensure the boiler does not fire up when there is no demand for heat.
|
|
|
Power Flushing: The sludge going around you central heating system gets baked onto the heat exchanger in your boiler, this slows the water from leaving the boiler. This causes the boiler to heat the water that has already been heated and start to overheat. The sludge and lime scale in your system, are good insulators of heat, therefore the boiler has to overwork again heating these two useless products in your system. Over time this is going to get worse and waste a lot of energy! Simple solution is to flush it out and inhibit the systems with the correct chemical to stop it happening again.

Using the above methods where applicable can significantly reduce your gas bill every year. It also offers a smoother running and a better performing system if set up correctly. To see how you could become more energy efficient, get in contact.
