Please bear with me for a short while, as I try and explain what's afoot..
My mothers property is a large house, which has currently got a rayburn range doing both heating and hot water. However this unit has 2 problems...
1. it isn't really quite big enough, since the property has been extended since it was installed. (Property has I think 17 radiators now, and might well rise to 19 or 20 with some changes required...)
2. it sprung a leak before Christmas and has a slow drip internally now, not causing an issue right now but will surely get worse in the future.
With the above things in mind, the plans was as follows:
Have the range converted to cooking only (it has bee suggested this can be done by putting sand in the heat exchanger, disconnecting the water obviously, or by replacing the exchanger with fire bricks filling it up so it becomes basically a giant storage heater.)
And having a modern boiler installed.
The grand pla is mum to run a b and b, with 2 rooms to begin with, rising to 3 rooms maybe 4 in due course.
Initially there will be 2 rooms each with a dedicated bathroom with showers etc..., later it will probably be 3 rooms with a shower each, a 4th room would only be added as an additional bed space for children, linked to one of the other rooms and share their bathroom.
The house already has another bathroom linked to my mothers room.
We had been erring towards a large 40+ Kw combi, but we have started to doubt this is the right way to go, even though it would seem that a combin with 25l capability would be good to run 3 showers simultaneous, it seems this is doubtful to work even though our water pressure seems to be pretty good.
What I would like is advice on what sort of boiler and system would be best, sizing for water tank - type of tank and any other advice!
I can of course supply more info to assist with this!
cheers
Andy
Extra background:
The current rayburn i think is only really capable of supplying around 11 rads or so, but just about copes with getting the house warm on a good day, but doesnt d it fast enough really. I think its total output is 20kw t hot water (CH plus cylinder) and its total heat input is 30kw to water and cooking areas.
