Help finding a new boiler or 2?

pleasedelete

I have a 6 bedroom 4 storey house. Guy who owned it before was a DIY addict and we have some unusual features!

My gas bill is £2.5k a year. We have a big new aga but the main issue is the boilers. There are 2 and they work perfectly but are at least 15 years old. We have 2 distinct sets of radiators in the house but as far as I can tell both boilers do both sets rather than 1 each.

I want to replace them. Would I still need 2?

Next challenge. They are in the garage and I would like the boiler in the house. We have a cellar but it has limited outdoor wall space and it is high up (the land outside has been built up by about 3 foot) and so most of the cellar walls are underground.

There is no other place with an outside wall on the 1st 2 floors as we have lots of big windows and are semi detached.

Any thoughts?

A RGI, recommended to you by a source you trust, could conduct a site survey, discuss your requirements/options and prepare a full specification quotation. More here.

A gas boiler doesn't have to be on an outside wall. The modern room-sealed ones will feed through a few metres of flue pipe, provided there aren't too many bends.

Something else to think about with a modern boiler is where the drain from the condenser is going to go. Almost all new boilers are condensing, so they need a pipe to drain the water away. From personal experience, it's a lot better if you can route this internally to an existing waste pipe. If the pipe has to run outside, it can freeze solid when you most need the heating.

As Canucklehead says, get a proper qualified gas fitter around to advise you of options.
