Quote for a new Combi boiler

wiseguy80

Hi,
I am looking to get a quote for fitting a new combi boiler in my house.

I live in a split level maisonette. The house has one very old wall mounted conventional boiler fitted in kitchen. The hot water tank is in in a cupboard in the floor above the boiler. The cupboard has enough space for the boiler to be fitted. All central heating pipes are going from there as well, so I was thinking may be I can get the combi boiler fitted in there.

I live in East Berkshire (Langley/Colnbrook) area. I was wondering if there are any plumbers out there who might be interested in doing the job? Please reply on this forum or send me a private message.

Thank you.

Combi boilers dont use a water storage facility such as the old fashioned "hot water tank" that are inevitably fitted with delightfully bright red lagging :eek: - they heat water continuously to a given temperature, so that you have hot water on demand and the combi-boiler has to be fitted to an external wall, to allow the fumes to be vented, so couldnt be fitted inside an internal cupboard

Really? I didn't know that, since when has this been the case?

Thanks, It's really appreciated. I was thinking if we can have the vent from the roof.

But if it's not possible, my current boiler is actually fitted on the external wall. But that means that there will be some pipework needed to move existing central heating pipes to the place of new combi boiler.

Any body knows what would be fair quote for this work. Just estimate.

i've just had a quote to remove my back boiler and resite a combi in the kitchen for £2.5k , this will involve removing hot water tank etc and remove any unwanted pipework

Thanks.
I got a very similar quote this morning for a Vaillant combi boiler. Looks like this is what I have to spend. I was more looking towards the 2K mark.

I think you can happily install a combi boiler inside a cupboard, but you do need to vent to the outside somewhere and there is apparently a safe limit to how far you can vent (something like 1m/1.5m maximum) so I would assume thats why most combi boilers are installed on external walls - for convenience when it comes to venting.

In this case I suppose it would depend where the old boiler tank cupboard is located in the house. My combi is in a kitchen cupboard with about a 0.5m vent duct and does just fine

Sorry Bosseyed, I was being sarcastic. You can of course install on an internal wall, the flue obviously goes to the outside. All manufacturers specify the total length allowable under different configurations, some of which are massive.

Whoops! Sorry, I didn't pick up on that, but then I can be spectacularly dense.....:rotfl:
