Combi heating boiler installation without crying
Most modern boilers are condensing gas boiler and a combi gas boiler is of this form. combi gas fired boilers are very cost-efficient and are able to heat water as required making them very common.
Before you purchase a combi boiler you should have an installation study to ensure it can be fitted in your house. If you use a trained heating installer to conduct a study they will ensure that you comply with the building rules. Just because you had a conventional gas fired boiler install does not mean that you can do a straightforward swap for a condensing heating boiler as they have unique set up requirements.
The flue exhaust gases are cooler and less buoyant than for a traditional heating boiler, as a result they often condense very quickly and form an easily seen plume. Surface wetting by the exhaust gases is often seen near the flue outlet, this can impact on neighbouring properties, in the worst case scenario the output plume can impact people traveling by.
The design prerequisites for a condensing boiler flue are different from old gas fired boilers and your existing flue may not be suitable. To complete the installation you could find that the flue will need to be converted. The condensing heating boiler flue must also not be shared with any non-condensing gas gas appliance.
An external drain point is required to enable the removal of the condensation which will form within gas boiler.
Do not despair, most of these fitting problems can easily be defeat. You should expect your fitter to advise you on the best way of tackling these issues based upon their previous experience. You should remember that these one-off fitting costs should be offset against the annual reduced running costs of the re placement condensing gas fired boiler.
Whilst you are having the new boiler fitted there are some alternatives for the set up. A change of gas fired boiler location is often necessary. If your existing boiler was an open flue or back gas fired boiler this will definitely be the case. You will see that these older gas boiler forms are not mounted on an outside wall with an existing gas fired boiler flue.
Most rooms in the home can be used other than the main living room. Sometimes the kitchen is utilised, sometimes a bedroom and on occasion the loft.
A heating boiler can be set up in the loft as long as the system is sealed. If you have selected this alternative you must ensure that there is access to the loft through a hatch with a lower down loft latter. Boarded flooring will be required to facilitate access to the gas boiler and sufficient lighting is it essential. All this is so the plumber can gain access quite easily to the boiler to repair or maintain it.
