What Are the Several types of Boilers Available

There are three main forms of boilers: Combination, System and Open Vent.

Combination Boilers

Combination boilers (combi boilers) are the most popular boiler that is fitted in the united kingdom at the moment. Combination boilers are units that take away the need for a warm water tank, and so save space in the house as no airing cupboard is necessary no space is adopted in the loft. As the name suggests, combination boilers combine two functions - not merely do they provide hot water to a property, they also become a central heating boilers. Combination boilers run 'on demand' which means they provide instant hot water when required.

Pros of combination boilers:

- Space saving.
- Saves money because there is no hot water tank which has to be constantly heated to keep the water hot.
- Water received through taps and other outlets is at mains pressure

- Less pipe work is required when installing so installation is normally quicker.

Cons of combination boilers:

- As the water given by combination boilers is 'on demand' at mains pressure, if several outlets are opened as well (taps/showers/washing machines) the pressure could be reduced depending on how powerful the boiler is.

System Boilers

System boilers (sealed system boilers) comprise of a sealed unit that usually runs at about 1 bar of pressure. System boilers require a water storage cylinder to store the hot water for the property, which is generally installed within an airing cupboard.

Pros of system boilers:

- Good for homes with more than one bathroom because the kind of boiler system can deliver hot water, at the same pressure, to many outlets simultaneously.
- No dependence on an expansion tank in the loft thus giving you more space for storage in the attic.
- High water pressure.

Cons of system boilers:

- Can be expensive to correct and install.
- Airing cupboard is required.

Open Vent Boilers

Open vent boilers are often linked to two tanks housed in the loft space of a house. One of these brilliant tanks is a small 'feed and expansion' tank that is used to supply water to the boiler and radiators, the other is a larger cool water storage tank which gives the water necessary for an open vented hot water cylinder.

Pros of open vent boilers:

- Mainly used in properties where there are many outlets (taps etc.) which may be used simultaneously.
- Relatively inexpensive to replace.

Cons of open vent boilers:

- Low water pressure.
- If the warm water cylinder empties you could have to wait a while for this to re-fill and then warm up.
- Boiler installation Colchester up a great deal of space in comparison to other boilers.

As you can plainly see there are advantages and disadvantages for each kind of boiler, for anyone who is still unsure concerning which boiler will best work for you, most good boiler installers will advise as per the list below:

If you have a set or bungalow without roof space - Combi Boiler.
If your premises has 2 or even more bathrooms - System or Open Vented.
If you are within an area with low mains water pressure - System or Open Vented.
If you are looking to upgrade an existing conventional boiler to high efficiency - System, Open vented or Combi.
If there are lots of people in your property requiring hot water on demand - Combi or System boiler with a warm water cylinder.
If your property is a loft conversion - Combi.

When purchasing boilers for installation in the home, or at work, it will always be advisable to contact an installer who has all the relevant qualifications to perform the work accurately and safely. A reputable installer of boilers may also offer you the best advice as to which system will suit the needs you have. Do not try to install a boiler system yourself if you don't are fully qualified.
