Exchanging your boiler with a combination
There many forms of condensing gas fired boiler and one main type is a combination heating boiler. combi gas boilers are very common in the UK and heat water when required.
They cannot be fitted to all homes and you should have a heating study finished before you buy one on this type. Fitting a combi gas boiler requires conformity with the latest building regulations and your heating surveyor will ensure that you do not infringe the rules. Just because you had a conventional heating boiler install does not mean that you can do a direct swap for a condensing boiler as they have unique set up requirements.
Your flue exhaust gases will be less buoyant as they are cooler and usually form an easily seen plume. You may see surface wetting the areas which are close to the flue exhaust outlet, this can impact on neighboring properties, the plume can also cause problems for any people going by your home.
The design essentials for a condensing gas fired boiler flue are different from old heating boilers and your current flue may not be suitable. To defeat this the flue might need to be modified. The condensing heating boiler flue must also not be shared with any non-condensing gas appliance.
A liquid condensate forms within the gas boiler, and must be able to be released to a acceptable drain or soak away.
There are many ways to overcome these installation difficulties. This is where using an experienced fitter produces a prompt payback as they will know of the best solutions. Condensing gas fired boilers are typically more efficient than the older gas boiler that they replace and any additional installation costs should be set off against this reduced lifetime running cost.
On the plus side you do have some options for where your new heating boiler is fitted. Due to the different installation requirements a change of location is often necessary. The new of an open flue or back gas fired boiler are good examples of this. An external flue is often missing from the set up of these older gas fired boiler types.
Providing you do not instal the gas fired boiler in the primary living room most other rooms are ok. Sometimes the kitchen is utilised, sometimes a bedroom and on occasion the attic.
If you have selected a sealed system you can then install the heating boiler in the attic to save space. If you have taken this choice you must ensure that there is access to the attic through a hatch with a drop down ladder. Boarded flooring will be required to facilitate access to the gas boiler and sufficient lighting is it essential. common maintenance and servicing are essential and that is why this type of attic access is required.
