As Gas Safe registered Engineers you can be safe in the knowledge that we have the expert skill required to carry out repairs, servicing or to design and install, a new Central Heating Boiler that is right for your needs.

Whilst we would be happy to advise you, we are not tied to one particular manufacturer. Therefore we can competitively source the most suitable Boiler that's right for you.

By installing or replacing an old boiler system with a modern, efficient condensing boiler system and making some improvements to your central heating controls you could significantly reduce your home’s energy consumption, carbon footprint and reduce your home heating bills. For example if you upgrade from an old 'G' rated boiler to a new 'A' rated boiler then you could save as much as £310 per year and reduce your carbon footprint by saving 1,200kg of carbon dioxide per year.*

There are 3 types of Gas Boilers to consider.

Combi Boilers
On the Central Heating System side, Combi Boilers eliminate the need for a cold water feed tank in your loft by heating water in your central heating system which is filled direct from the water mains. On the Domestic Hot Water side, they work by taking cold water straight from the mains and heating it directly to supply hot water directly  to your taps. In this way you can have a continuous flow of hot water any time that you want. However, with this type of boiler you are restricted to having the water supplied at the pressure of the incoming Water Main.

Combi boilers have all of their components built into the boiler, offering a compact and attractive installation. You do not need a storage cylinder in the airing cupboard or a cold water feed tank (often stored in the loft) which can save a lot of space.

Because of the way that they heat your water, Combi boilers are also usually more efficient than other boiler types. You won’t lose heat through the storage tank, or have to burn more energy to reheat water that’s gone cold again.


System Boile
On the Central heating side, System boilers eliminate the need for a cold water feed tank in your loft by heating water in your central heating system which is filled direct from the water mains. On the Domestic Hot Water side however, system boilers keep the hot water storage Cylinder which is usually found in your airing cupboard. This can be an Unvented Cylinder, which would supply water at your taps at the incoming Water Main pressure, or if this pressure was inadequate then a booster pump may be installed.

System boilers have all of their components built into the boiler, offering a compact and attractive installation. They also allow you to do away with the loft tank, freeing up more space in your home and leaving you with less external components to maintain.

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.

Regular / Heat only Boiler
A regular / heat only 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.

*These are estimated figures based on installing a new A-rated condensing boiler and full set of heating controls in a gas-heated, semi-detached gas heated home with three bedrooms.
