Combi gas fired boiler fitting overview
Combi gas fired boiler fitting overview
A combi gas boiler is a type of condensing gas fired boiler. It renders water when called for and is the most common form of 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 form. This should be carried out by a trained installer as there are regulations that must be complied with. There are many reasons why it is more challenging to install a modern condensing boiler and replace a traditional gas boiler.
The flue output gases are not as hot and less buoyant than for a conventional gas fired boiler, a visible plume can result as they rapidly condense. You may see surface wetting the areas which are near to the flue exhaust outlet, your neighbour’s house can also be impacted with this operation in the worst case scenario the exhaust plume can impact people passing by.
As condensing central heating boilers have diverse exhaust requirements from conventional heating boilers your present flue may not be acceptable. This might need the flue to be changed. The condensing heating boiler flue must also not be shared with any non-condensing gas appliance.
A liquid condensate will form inside a condensing heating boiler when it is operating and there should be a suitable outside drain point to permit this to be drained away.
An experienced installer will know how to easily beat most of these issues. The benefit of using a trained fitter is that they will know of these. These additional installation costs should be taken into the life-time cost assessment of the gas boiler.
Whilst you are having the new gas fired boiler fitted there are some alternatives for the installation. A change in the location of the new gas fired boiler often results from the different installation requirements. The replacement of an open flue or back heating boiler are good examples of this. An external flue is often missing from the set up of these older gas boiler types.
It is acceptable to install a gas gas fired boiler in any room other than the principal living room. Typical illustrations include the loft, sleeping rooms and of course the kitchen.
You can install a gas boiler in the loft as long as the system is of the sealed type. This will be an acceptable if the attic has a lower-down door latch with a loft latter. The loft would need to have adequate lighting and a boarded floor to facilitate access to the boiler. frequent maintenance and servicing are important and that is why this form of attic access is needed.
