There various types of condensing gas boiler and one main form is a combination boiler. One of the reasons why combi central heating boilers are very popular is that they can heat water when needed.
As they have specific installation requirements it is essential that you have an heating audit conducted before you complete on the buy. If you use a trained heating installer to conduct a audit they will ensure that you comply with the building rules. It is sometimes more difficult to install a condensing rather than a non-condensing boiler for various reasons.
The exhaust gases from the flue tend to be cooler and hence less buoyant than for an older gas fired boiler form an easily seen plume can often be the result as the cooler gases will condense more quickly. They may cause wetting of areas too close to the end of the flue,, this impact is not restricted to your home and can spill over on to neighbouring properties, the plume can also cause irritation for any people traveling by your home.
An existing flue designed for a non-condensing gas boiler is unsuitable for a condensing boiler and vice versa. To complete the fitting you could find that the flue will need to be converted. The condensing gas boiler flue must also not be shared with any non-condensing gas appliance.
An external drain point is needed to facilitate the removal of the condensation which will form within boiler.
Many of these matters have been faced by other householders and there are simple solution is to overcome them. The advantage of using a trained fitter is that they will know of these. Condensing heating boilers are typically more efficient than the older boiler that they replace and any extra set up costs should be set off against this reduced life-time running cost.
Having a new gas fired boiler set up allows you some alternatives on the positioning of the new heating boiler. The new installation requirements will often dictate a change in gas fired boiler location. The replacement of an open flue or back heating boiler are good illustrations of this. They are often missing an external flue.
Most rooms in the house can be used other than the main living room. In addition to the kitchen or utility room often the attic or bedrooms are used for gas fired boiler set up.
setting up the boiler in the loft often saves room and it is possible providing that the gas fired boiler is a sealed system. Access to the attic has to be provided through a drop down loft latter attached to the loft hatch. The floor has to be boarded from the hatch to the heating boiler location and there has to be sufficient lighting in the loft. This will permit an engineer to get access to the heating boiler for maintenance and servicing.

can a combi gas boiler be fitted on a upstairs landing beteen 2 bedrooms
For the specific siting of a combi boiler you will need the opinion of an onsite heating advisor / fitter as there are regulations to comply with and true confirmation can only be established with an inspection.
Talking in general terms you would be surprised where a combi can be fitted.
If you look at http://britishgas.boiler-systems.co.uk/heating-controls/ you will see answers to questions confirming: -
1. Gas boilers can be put in an upstairs bedroom airing cupboard with an outside wall
2. Gas boilers can be fitted in a bathroom that is upstairs. The boiler can be either vertically flued or if the bathroom contains an external wall, it can flue that way
Also in the combi frequently asked questions http://britishgas.boiler-systems.co.uk/boiler-questions/ there is a response
3. Can a boiler be installed in a loft?
Yes, a boiler can be installed in a loft as long as the system is sealed. The loft itself has to have a drop down ladder attached to the hatch,the floor has to be boarded from the hatch to the boiler location and there has to be adequate lighting up there so the engineer can gain access quite easily to the boiler to repair or maintain. Also the standard ventilation requirements also apply.
So – quite a lot of flexibility provided that the ventilation can be provided and the position conforms to the boiler manufacturers specifications.
