Heating and hot water systems
Production of heat and hot water for our homes uses the majority of the energy we consume. By making improvements to your heating and hot water systems you will see real tangible differences in reduced fuel bills and your associated carbon emissions.
Heating and Hot Water Boilers
With a conventional heating system there is a choice of 2 main boiler types, whichever fuel type you use to power the boiler; gas, oil or LPG.
Conventional boiler types
- Combination boiler (combi boiler) that provides both your heated water for the radiators and hot water for your taps
- Regular, system or open vented boilers which supply your heated water for the radiators and is also connected to a hot water cylinder. The hot water cylinder stores the hot water which supplies your hot water taps
What is a condensing boiler?
Currently a modern condensing boiler is the most efficient way to heat water. Both types of conventional boiler, mentioned briefly above, are available as a condensing boiler, e.g. condensing combi boiler, regular condensing boiler.
Should I install a regular boiler/cylinder or combi boiler system?
A combi boiler can often be cheaper to run, as the water is only heated when and as you need it. A combination boiler does not require a hot water cylinder and therefore can have space saving benefits. However, if you have issues with low water pressure and/or have a number of bathrooms, a combi system may not be suitable.
Whichever boiler you decide is the most appropriate for your home, it is essential that the heating system incorporates an efficient set of heating controls.
Be sure to discuss the best boiler option for your property with a suitably experienced and qualified heating engineer.
Do you have a band G boiler?
If you have a band G boiler, you may be eligible for the boiler scrappage scheme, whereby you receive £400 towards the cost of a new condensing boiler.
How can I tell if I have a band G boiler?
If your boiler has a permanent pilot light it is quite likely to be a band G-rated boiler. Also, the following scenarios may indicate your boiler is rated in band G.
- Gas fired and older than 15 years old
- Oil fired and over twenty five years old
- Floor Standing Boilers - Pre 2002 with permanent pilot ignition
- Wall mounted boilers - Pre 2002 with cast iron heat exchanger and permanent pilot ignition
- Combi boilers - Pre 1998
- Back Boilers - Pre 2002
