Fitting your new combination heating boiler
Fitting your new combination heating boiler
There various forms of condensing boiler and one main type is a combi heating boiler. The benefit of a combi boiler is that it can heat water when needed and for this reason they are very common.
Before you buy a combi gas fired boiler you should have an installation audit to ensure it can be fitted in your house. If you use a trained heating fitter to conduct a study they will ensure that you comply with the building rules. It is sometimes more difficult to install a condensing rather than a non-condensing gas boiler for many reasons.
Your flue exhaust gases will be heavier as they are not as hot with less heat they can condense more rapidly and result in a visible plume. You may see surface wetting the regions which are near to the flue exhaust outlet, this can impact on neighboring properties, the plume can also cause problems for any people going past your house.
The design requirements for a condensing gas boiler flue are different from old central heating boilers and your existing flue may not be acceptable. As a result you may need to modify the flue. Also the flue for a condensing gas fired boiler must not be shared with any non-condensing gas appliance.
A liquid condensate develops within the gas fired boiler, and must be able to be discharged to a acceptable drain or soakaway.
Many of these matters have been faced by other householders and there are simple solution is to defeat them. The benefit of using a trained installer is that they will know of these. Condensing gas fired boilers are typically more efficient than the older boiler that they replace and any extra set up costs should be set off against this reduced lifetime running cost.
Whilst you are having the new boiler fitted there are some options for the set up. A change of heating boiler location is often necessary. This is a certainty when the elderly boiler was an open flue or back boiler. An outside flue is often missing from the installation of these older gas boiler types.
Providing you do not install the heating boiler in the main living room most other rooms are acceptable. Typical illustrations include the loft, sleeping rooms and of course the kitchen.
A gas fired boiler can be put in in the attic as long as the system is sealed. incremental essentials in this situation are that the attic has a lower-down latch with a ladder. The floor has to be boarded from the hatch to the gas fired boiler location and there has to be adequate lighting in the loft. Regular maintenance and servicing are essential and that is why this form of loft access is needed.
