Carefree combination gas fired boiler installation

A combi boiler is a form of condensing gas boiler. It provides water as called for and is the most common form of gas fired boiler in the UK.

They cannot be fitted to all houses and you should have a heating audit completed before you buy one on this type. If you use a trained heating fitter to conduct a study they will ensure that you comply with the building rules. Just because you had a traditional boiler install does not mean that you can do a straightforward switch for a condensing boiler as they have particular installation requirements.

The flue exhaust gases are not as hot and less buoyant than for a orthodox boiler, an easily seen plume can result as they rapidly condense. areas near to the flue outlet are often subject to surface wetting, your neighbour’s home can also be impacted with this operation the plume can also cause irritation for any people traveling by your home.

An existing flue designed for a non-condensing boiler is unsuitable for a condensing heating boiler and vice versa. This might need the flue to be converted. The condensing boiler flue must also not be shared with any non-condensing gas appliance.

A liquid condensate will form inside a condensing boiler when it is running and there should be a acceptable outside drain point to permit this to be drained away.

An experienced installer will know how to easily beat most of these problems. You should expect your fitter to advise you on the best way of tackling these problems based upon their earlier experience. Condensing gas fired boilers are typically more efficient than the older gas boiler that they replace and any incremental fitting costs should be set off against this reduced life running cost.

It is not all doom and gloom however and there are options for the installation. Due to the different fitting requirements a change of location is often necessary. If your existing gas fired boiler was an open flue or back boiler this will unquestionably be the case. An outside flue is often missing from the fitting of these older gas fired boiler types.

It is acceptable to install a gas boiler in any room other than the main living room. Typical examples include the attic, bedrooms and of course the kitchen.

Providing you have a sealed system you can install a gas fired boiler in the attic. If you have taken this option you must ensure that there is access to the loft through a hatch with a lower down attic ladder. The floor has to be boarded from the hatch to the boiler location and there has to be adequate lighting in the attic. These points are called for to facilitate a plumber to maintain and service the boiler.
