Setting up your new combi gas boiler
Setting up your new combi gas boiler
A combi heating boiler is a form of condensing heating boiler. One of the reasons why combi central heating boilers are very common is that they can heat up water when required.
As they have specific set up requirements it is essential that you have an heating audit conducted before you complete on the purchase. The gas boiler fitting regulations are intricate and need to be interpreted by a trained heating installer. Just because you had a conventional gas fired boiler install does not mean that you can do a direct swap for a condensing gas fired boiler as they have specific set up requirements.
Not as hot exhaust gases released from the flue are less buoyant a visible plume can result as they quickly condense. areas near to the flue outlet are often subject to surface wetting, your neighbour’s home can also be impacted with this process in the worst case scenario the exhaust plume can impact people going past.
You could find that your present flue, whilst suitable for a noncondensing boiler, is not acceptable for your replacement gas boiler. To defeat this the flue might need to be modified. The condensing gas boiler flue must also not be shared with any non-condensing gas appliance.
You need to be able to drain away the liquid condensation which will form within the boiler.
An experienced installer will know how to easily beat most of these issues. You should expect your fitter to advise you on the best way of tackling these matters based upon their earlier experience. These incremental fitting costs should be taken into the life cost assessment of the gas fired boiler.
The new boiler positioning does not have to be in exactly the same place as the older gas boiler. A change of gas fired boiler location is often necessary. Specific illustrations are where a condensing gas fired boiler is to replace an open flue or back gas fired boiler. You will see that these older boiler types are not mounted on an external wall with an existing boiler flue.
It is acceptable to install a gas heating boiler in any room other than the main living room. Typical illustrations include the loft, bedrooms and of course the kitchen.
Providing you have a sealed system you can set up a gas boiler in the loft. Access to the attic has to be provided through a lower down loft latter attached to the attic hatch. Access to the gas fired boiler should be provided over a boarded floor and you need to ensure that there is enough lighting in the loft. common maintenance and servicing are essential and that is why this form of loft access is needed.
