Hi,
As part of the modernisation plans for our soon-to-be-bought house, I'm wanting to replace the coal-fired back-boilered central heating with a modern condensing boiler.
Currently the coal fire is in/about the geomentric centre of the house, fireplace to the front room, with the chimney rising up to the apex of the roof. The kitchen is at the rear of the house, backing onto the chimney-breast, which is where I want to locate the boiler. The ideal spot would be in the shallow corner formed by the kitchen wall and the chimney breast, as then I have easy access to the chimney for the boiler flue, as well as the hot water plumbing which I'm hoping to find behind the old coal fire..
I understand that I'd need to find a boiler that can cope with a flue of the required vertical rise (it's a 2story house), and as a condensing boiler it may also need a condensate drainage solution (around the back of the kitchen cabinets to the kitchen drain).
My questions are:
1. The chimney has 2 pots, for which I assume that it has 2 flues within it. Is this assumption correct?
2. Would these 2 flues be a pair of parallel isolated chambers? (it's a 60's brick built house) The chimney breast through each room (downstairs and upstairs) is quite wide (over 1m)
3. If it's a single chamber, and the coal-fired boiler has a flue liner (it's a fairly young looking Charnwood LA50 fire/boiler), could another flue liner/segments be installed next to it in the single chamber?
4. Would a balanced flue work in this situation, assuming I can physically install the flue components, if not, would this limit my choice of boilers, as most seem to have a balanced flue as the default option (is it compulsory now?) or can a balanced flue boiler be adapted to take air from elsewhere?
kitchen fitting the boiler is the most desirable location, if all the above can be made to work - unfortunately there's a conservatory and doors/windows along the back wall to make locating a shorter horizontal flue there impossible.
Thanks for any thoughts.
p.s. yes I will be getting a gas engineer in to do the work, I just need to know I'm asking him to do something achievable.
