Substituting your boiler with a combination
Substituting your boiler with a combination
Your next gas boiler will probably be a combination boiler, a type of cutting-edge condensing heating boiler. combi heating boilers are very popular in the UK and heat water on demand.
As they have specific fitting requirements it is essential that you have an heating audit conducted before you complete on the buy. Fitting a combination gas boiler requires conformity with the latest building regulations and your heating surveyor will ensure that you do not contravene the rules. It is sometimes more difficult to set up a condensing rather than a non-condensing gas fired boiler for many reasons.
Not as hot exhaust gases discharged from the flue are less buoyant and usually form a visible plume. Surface wetting by the output gases is often seen near the flue outlet, your neighbour’s home can also be impacted with this process the plume can also cause irritation for any people passing by your house.
You could find that your present flue, whilst suitable for a noncondensing heating boiler, is not acceptable for your new heating boiler. To complete the set up you could find that the flue will need to be converted. The flue cannot be shared and must be for the individual use of condensing appliances.
A liquid condensation will form inside a condensing heating boiler when it is operating and there should be a acceptable external drain point to allow this to be drained away.
There are many ways to defeat these fitting difficulties. This is where employing an experienced fitter produces a quick payback as they will know of the best solutions. You should remember that these one-off installation costs should be offset against the yearly reduced running costs of the re placement condensing heating boiler.
Having a new gas fired boiler installed allows you some choices on the positioning of the new boiler. A change of gas fired boiler location is often necessary. The replacement of an open flue or back gas boiler are good examples of this. These are often mounted in an interior position away from an external wall.
It is acceptable to install a gas heating boiler in any room other than the principal living room. In addition to the kitchen or utility room frequently the attic or bedrooms are used for gas fired boiler set up.
You can install a boiler in the loft as long as the system is of the sealed type. Access to the loft has to be provided through a lower down loft latter attached to the attic hatch. Boarded flooring will be called for to facilitate access to the gas boiler and enough lighting is it essential. Regular maintenance and servicing are important and that is why this type of attic access is required.
