Combi gas boiler fitting without tears
Most modern central heating boilers are condensing gas fired boiler and a combi heating boiler is of this form. combi central heating boilers are very common in the UK and heat water as needed.
A heating study is recommended before you buy to ensure that it is able to be put in in your house. The heating installer will ensure that your proposed fitting complies with the latest building rules. If you are exchanging your existing gas fired boiler you will find that you cannot do a direct switch as it is now more difficult to install a modern-day condensing heating boiler.
The output gases from the flue tend to be cooler and hence less buoyant than for an aging gas boiler type an easily seen plume can often be the result as the not as hot gases will condense more quickly. You may see surface wetting the regions which are near to the flue exhaust outlet, this can impact on neighboring homes, in the worst case scenario the exhaust plume can impact people passing by.
The design requirements for a condensing gas fired boiler flue are different from old gas boilers and your existing flue may not be acceptable. To complete the set up you could find that the flue will need to be converted. The flue cannot be shared and must be for the single use of condensing appliances.
An external drain point is required to facilitate the removal of the condensate which will develop within heating boiler.
Experience has indicated that there are many different ways to beat any potential set up problems. The advantage 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 life-time running costs of the condensing boiler.
On the plus side you do have some alternatives for where your new boiler is fitted. A change in the location of the new gas fired boiler often results from the different set up requirements. If your existing gas boiler was an open flue or back heating boiler this will unquestionably be the case. You will see that these older gas fired boiler forms are not installed on an outside wall with an existing boiler flue.
Providing you do not instal the heating boiler in the main living room most other rooms are acceptable. Of course heating boilers are frequently set up in the utility room or kitchen but other frequent places are the bedrooms or installation of a heating boiler in the loft.
A gas boiler can be installed in the loft as long as the system is sealed. additional needs in this situation are that the attic has a lower-down latch with a ladder. Access to the heating boiler should be provided over a boarded floor and you need to ensure that there is capable lighting in the attic. frequent maintenance and servicing are essential and that is why this type of loft access is called for.
