There is a wide variety of Heating Systems avialable to you. Here at GM we are continuously working with our Engineers to train them to all levels and ranges on the market, From technical training to health and safety courses and tests, to maintain the highest standards. This ensures they can fit all ranges available. Please see below some various types of systems and there functions.

Back Boiler |
 |
|
Back boilers provide reliable heating and hot water, and allow you to draw hot water from more than one tap at the same time, without affecting other outlets. However, they need a lot of space - the boiler hidden behind your chimney, two tanks in the loft, and a cylinder in the airing cupboard.
Few people will consider a back boiler unless they already have that system in place as other, newer systems can easily handle the demands of a large home without taking up as much space. But if you already use a back boiler, you’ll save a lot of money by sticking with the same system when the time comes to replace your boiler. |

Condensing |
|
|
Condensing boilers capture the heat that is normally lost by traditional boilers and reuses it. This means that a top of the range A-grade boiler could have as much as 96 per cent efficiency. |
|
Oil Fired |
|
|
An oil fired boiler, especially a condensing model, can give an efficiancy rating of up to 98% just as gas can. Oil fired combination boilers are also available but it should be noticed that the hot water on demand feature of a combination boiler is a little slower in the oil boiler field. Oil boilers can be fitted with balanced flues or with open flues but we would suggest that a balanced flue boiler is much more versatile, efficient and can be used in more siting locations. |
|
Sealed Systems |
|
|
A system boiler (also known as a closed or sealed system boiler) works on the principle of stored hot water. This means that you will need an airing cupboard or other space for the hot water storage tank. Although a tank is needed in the airing cupboard, a system boiler still needs less space than a traditional open vent or heating only boiler, which utilises a second tank in the loft. Also, many of the individual components of the heating and hot water system are built in, which means that installation is quicker, neater, easier and more efficient. With a system boiler you can run hot water from a range of outlets simultaneously, without someone else’s shower running cold on them. You will also get good water pressure.

Replacement |
|
|

You may have had an extension to your home and need to upgrade your existing system, or maybe your old boiler is just inefficient. Whatever your reasons for replacing your system GM will help you make the right decision and replace to your requirements in minimal time. |

Solar |
|
|
 Over 70% of the average household’s energy use goes into space and water heating, so a source of free hot water to use instead of commercial energy can make a dramatic financial saving. Solar Water Heating is the renewable technology of choice for most UK households as it offers a quicker payback (7-15 years for an average household) than Photovoltaics (20-30 years) and the advantage is GM Heating and Plumbing are already part of an established network of installers.

Vented and Unvented |
|
|
An open vent boiler is the existing system in most people’s homes. This type of system uses two water tanks, both located in the loft, and a hot water storage cylinder in the airing cupboard so it is very space hungry. One tank draws water from the mains supply and feeds the storage cylinder which, when heated by the boiler, can release hot water to taps all over the house.
The second tank is the feed and expansion tank which contains the correct level of water for your heating system, allowing for water expansion when you turn the heat on.
Showers, taps and running baths can be drawn in any room at the same time, but be aware that if the cylinder should run cold it will take a little time to reheat.
Many people switch from a traditional open vent boiler to an open vent sealed system boiler. This is a relatively cheap switch to make and will cut the need for one of the tanks in your loft. |
