Combination gas fired boiler fitting overview
Combination gas fired boiler fitting overview
Any combination gas fired boiler is a modern-day efficient form of condensing gas boiler. combination central heating boilers are very efficient and are able to heat water when called for making them very popular.
They cannot be fitted to all houses and you should have a heating study finished before you buy one on this form. Putting In a combi boiler requires compliance with the latest building regulations and your heating surveyor will ensure that you do not contravene the rules. Just because you had a traditional heating boiler install does not mean that you can do a direct swap for a condensing gas fired boiler as they have particular fitting requirements.
The output gases from the flue tend to be not as hot and hence less buoyant than for an aging heating boiler form a visible plume can often be the result as the cooler gases will condense more quickly. areas near to the flue outlet are often subject to surface wetting, neighboring properties can be impacted by this effect, or worse still in the plume can cause problems for people going by.
Your existing flue may not be suitable for a modern-day condensing boiler requirements. As a result you may need to change the flue. The flue cannot be shared and must be for the single use of condensing appliances.
A liquid condensate will form inside a condensing gas fired boiler when it is operating and there should be a suitable external drain point to permit this to be drained away.
An experienced installer will know how to easily beat most of these problems. The benefit of using a trained fitter is that they will know of these. Whilst some of these fixes will add to the fitting cost you will then need to setoff these against the reduced lifetime running costs of the condensing heating boiler.
It is not all doom and gloom however and there are choices for the fitting. The new installation requirements will often prescribe a change in heating boiler location. The most common illustrations of this are where an open flue or back gas fired boiler is being replaced. They are often missing an external flue.
Most rooms in the household are available for the set up with the exception of the primary living room. Typical examples include the loft, sleeping rooms and of course the kitchen.
You can install a boiler in the attic as long as the system is of the sealed type. This will be an acceptable if the attic has a lower-down latch with a attic ladder. Boarded flooring will be called for to facilitate access to the gas boiler and capable lighting is it essential. This will allow an engineer to get access to the heating boiler for maintenance and servicing.
