Setting up a combi gas boiler
There various types of condensing gas fired boiler and one main form is a combi boiler. The advantage of a combination gas boiler is that it can heat water when needed and for this reason they are very common.
A heating audit is recommended before you buy to ensure that it is able to be set up in your house. Setting up a combination heating boiler requires conformity with the latest building rules and your heating surveyor will ensure that you do not infringe the rules. There are many reasons why it is more challenging to install a contemporary condensing boiler and replace a traditional gas boiler.
The output gases from the flue tend to be not as hot and hence less buoyant than for an older gas fired boiler form as a result they often condense very quickly and form an easily seen plume. You may see surface wetting the regions which are close to the flue exhaust outlet, neighbouring properties can be impacted by this effect, in the worst case scenario the output plume can impact people traveling by.
As condensing heating boilers have different exhaust requirements from orthodox central heating boilers your present flue may not be suitable. This might need the flue to be converted. The flue cannot be shared and must be for the solitary use of condensing appliances.
The set up will also need to take into account the necessity for an external drain point for the liquid condensate which forms inside the gas fired boiler.
There are many ways to defeat these installation difficulties. The advantage of using a trained installer is that they will know of these. These extra installation costs should be taken into the life cost assessment of the boiler.
Having a new gas boiler put in allows you some options on the positioning of the new gas boiler. A change of location often results from the new installation requirements. This is a certainty when the aging boiler was an open flue or back gas boiler. You will see that these older gas fired boiler types are not mounted on an external wall with an existing gas boiler flue.
Most rooms in the home are available for the fitting with the exception of the primary living room. Typical examples include the loft, sleeping rooms and of course the kitchen.
A gas boiler can be fitted in the attic as long as the system is sealed. extra necessities in this situation are that the loft has a drop-down door latch with a attic ladder. Access to the gas fired boiler should be provided over a boarded floor and you need to ensure that there is sufficient lighting in the attic. All this is so the plumber can gain access quite easily to the heating boiler to repair or maintain it.
