Any combi boiler is a cutting-edge cost-efficient type of condensing heating boiler. combi central heating boilers are very cost-efficient and are able to heat water when needed making them very popular.
As they have specific fitting requirements it is important that you have an heating survey conducted before you complete on the purchase. The gas gas boiler set up regulations are complicated and need to be considered by a trained heating installer. There are various reasons why it is more challenging to install a contemporary condensing gas boiler and replace a conventional gas boiler.
Your flue output gases will be less buoyant as they are not as hot a visible plume can often be the result as the cooler gases will condense more quickly. Surface wetting by the output gases is often seen near the flue outlet, or cause a nuisance to neighbouring property, on occasion people passing by your home can be impacted by this exhaust plume.
The design prerequisites for a condensing heating boiler flue are different from old boilers and your current flue may not be suitable. To complete the fitting you could find that the flue will need to be changed. If you want to share the flue it can only be achieved with another condensing appliance.
An external drain point is required to enable the removal of the condensation which will develop within gas boiler.
An experienced fitter will know how to easily overcome most of these issues. You should expect your fitter to advise you on the best way of tackling these problems based upon their previous experience. These extra installation costs should be taken into the life-time cost assessment of the boiler.
Whilst you are having the new boiler fitted there are some options for the set up. Due to the different fitting requirements a change of location is often necessary. If your existing boiler was an open flue or back heating boiler this will definitely be the case. An outside flue is often missing from the fitting of these older gas fired boiler types.
Most rooms in the house can be used other than the main living room. Sometimes the kitchen is utilised, sometimes a bedroom and on occasion the attic.
Providing you have a sealed system you can instal a gas boiler in the attic. In this situation the attic has to have a drop down attic ladder attached to the hatch. The attic would need to have sufficient lighting and a boarded floor to facilitate access to the heating boiler. Regular maintenance and servicing are essential and that is why this form of loft access is called for.
