Installing a replacement boiler
Installing a replacement boiler
There various types of condensing gas boiler and one main form is a combination heating boiler. The advantage of a combi gas boiler is that it can heat water when needed and for this reason they are very common.
Before you buy a combination gas boiler you should have an fitting study to ensure it can be fitted in your house. The heating installer will ensure that your proposed fitting complies with the latest building regulations. There are various reasons why it is more difficult to install a modern condensing boiler and replace a traditional gas boiler.
Your flue output gases will be less buoyant as they are cooler an easily seen plume can result as they rapidly condense. They may cause wetting of surfaces too close to the end of the flue,, or cause a nuisance to neighbouring property, on occasion people traveling by your house can be impacted by this output plume.
You could find that your existing flue, whilst suitable for a noncondensing gas fired boiler, is not acceptable for your new gas boiler. To complete the set up you could find that the flue will need to be modified. If you want to share the flue it can only be achieved with another condensing appliance.
You need to be able to drain away the liquid condensate which will form within the heating boiler.
Do not worry, most of these fitting problems can easily be overcome. This is where using an experienced installer produces a prompt payback as they will know of the best solutions. The set up assessment process should estimate the extra cost of the full installation and compare them with average fuel savings over the life-time of the new boiler.
Whilst you are having the new gas fired boiler fitted there are some options for the fitting. A change of heating boiler location is often necessary. If your existing gas fired boiler was an open flue or back gas boiler this will definitely be the case. They are often missing an external flue.
Most rooms in the house can be used other than the main living room. Typical examples include the loft, bedrooms and of course the kitchen.
You can install a heating boiler in the attic as long as the system is of the sealed form. If you have selected this choice you must ensure that there is access to the loft through a hatch with a drop down attic ladder. Boarded flooring will be needed to facilitate access to the gas boiler and adequate lighting is it essential. Regular maintenance and servicing are essential and that is why this type of loft access is needed.
