What is central heating?
Central heating is the most common system for heating homes in the UK.
The 3 main type of heating systems are Wet (most common), Warm air and Storage heaters.
How does a wet system work?
Hot water circulates through a system of pipes to radiators throughout the property. At the centre of the system is the boiler, this heats the water through a heat exchanger and then pumps the hot water around the system. Radiators then use convection to warm the air around them which naturally rises, in turn the cool air in the room falls lower and so the warm air circulates around the room to reach the desired temperature.
Over time as water passes through the system corrosion naturally occurs, the consequences of this can be costly if the boiler or radiator fail due to blockages. The best ways to counter this problem is to make sure the boiler is regularly serviced and the correct chemical is used to clean the system and inhibitor added for long term protection.
Reflector foil can be used behind radiators mounted on external walls that reflects up to 95% of the wasted heat energy radiated from the rear of a radiator back into the room. This can reduce your heating bill as the rooms will heat up quicker and the boiler won’t need to run as long.
A high efficiency condensing boiler is more efficient than a non-condensing equivalent. This is achieved by making better use of the heat they generate from burning fuels such as gas or oil, typically making it at least 25% more efficient.
You can typically reduce heating bills by 25% when compared to a non-condensing boiler.
When condensing boilers are working at peak efficiency, the water vapour produced in the combustion process condenses back into liquid form releasing the latent heat of vaporisation. This water will then be piped away to a drain or soakaway. This by product will help save you money and reduce your carbon emissions.
Under UK law since 2005 all newly fitted gas boilers must be condensing
Condensing versions are available for combi, regular and system boilers and typically operate at over 90% efficiency.
We recommend installing new heating controls and thermostatic radiator valves to maximise efficiency and help reduce fuel bills when installing any new boiler. Ask us about the best boiler installation for you.
