Combi boiler installation can be achieved without problems if you select your combi installer with care.
There are various types of condensing gas fired boiler and one main type is the combination gas fired boiler or combi boiler. It renders water when needed and is the most popular form of gas fired boiler in the UK.
Combi boilers cannot be installed in all homes and you should have a heating study finished before you buy one of this type. The heating installer will ensure that your proposed fitting complies with the latest building regulations. There are various reasons why it is more challenging to install a contemporary condensing boiler and replace an orthodox heating boiler.
If you install a combi boiler your flue exhaust gases will be heavier as they are not as hot and an easily seen plume can result as they quickly condense. The output gases can then wet areas near to the outlet, this impact is not restricted to your house and can spill over on to neighboring properties, or worse still the plume can cause problems for people passing by if the flue is badly positioned.
The design prerequisites for a combi gas boiler flue are different from old boilers and your current flue may not be suitable. To complete the installation you could find that the flue will need to be changed. You cannot share a condensing gas fired boiler flue with any other non-condensing gas appliance.
A clear condensate forms within the heating boiler, and must be able to be released to a suitable drain or soakaway.
Do not worry, most of these set up matters can easily be defeated. A good fitter will know of these remedies and can advise you on the best approach to your combi boiler installation. These additional installation costs should be taken into the life cost assessment of the gas boiler.
On the plus side you do have some alternatives for where your new heating boiler is set up. A change of gas boiler location is often necessary. If your existing boiler was an open flue or back gas fired boiler this will definitely be the case. They are often missing an external flue.
Providing you do not set up the gas boiler in the main living room most other rooms are acceptable. In addition to the kitchen or utility room often the attic or sleeping rooms are sometimes used for gas fired boiler fitting.
Putting the gas boiler in the attic often saves room and it is possible providing that the gas boiler is a sealed system. In this situation the loft has to have a drop down loft ladder attached to the hatch. The attic would need to have adequate lighting and a boarded floor to enable access to the gas fired boiler. These requirements are so that subsequent maintenance and servicing can be performed by a central heating engineer.
