Combination heating boiler fitting without weeping
Most cutting-edge heating boilers are condensing heating boiler and a combination gas boiler is of this form. combi boilers are very economical and are able to heat up water when called for making them very common.
Before you buy a combi gas fired boiler you should have an fitting audit to ensure it can be fitted in your home. This should be carried out by a trained installer as there are regulations that must be complied with. If you are exchanging your existing boiler you will find that you cannot do a direct swap as it is now more difficult to install a modern condensing gas fired boiler.
The flue exhaust gases are cooler and heavier than for a traditional gas fired boiler, with less warmth they can condense more quickly and result in an easily seen plume. Surface wetting by the exhaust gases is often seen near the flue outlet, this can impact on neighboring houses, or worse still in the plume can cause problems for people going past.
An existing flue designed for a non-condensing heating boiler is unsuitable for a condensing gas boiler and vice versa. To complete the fitting you could find that the flue will need to be changed. The flue cannot be shared and must be for the solitary use of condensing appliances.
A liquid condensation will form inside a condensing heating boiler when it is running and there should be a acceptable external drain point to allow this to be drained away.
Experience has shown that there are many different ways to beat any potential installation problems. The benefit of using a trained fitter is that they will know of these. Condensing gas fired boilers are typically more efficient than the older boiler that they replace and any incremental set up costs should be set off against this reduced lifetime running cost.
Having a new gas fired boiler installed allows you some alternatives on the positioning of the new gas fired boiler. A change of heating boiler location is often necessary. This is a certainty when the aging heating boiler was an open flue or back gas fired boiler. They are often missing an external flue.
It is acceptable to install a gas boiler in any room other than the principal living room. Sometimes the kitchen is utilised, sometimes a sleeping room and on occasion the attic.
A heating boiler can be installed in the attic as long as the system is sealed. additional requirements in this situation are that the loft has a lower-down door latch with a loft latter. Access to the heating boiler should be provided over a boarded floor and you need to ensure that there is adequate lighting in the loft. These points are called for to enable an engineer to maintain and service the gas boiler.
