Hi - I am currently refurbishing a house and I'm replacing an ancient boiler with a new system. The problem is I'm struggling to get consistent advice from the plumbers I've had round to look at the job.
The house is roughly 3,300 sq ft with 3 bathrooms, downstairs wc etc. A number of plumbers have said we need at least 60kw+ from a boiler and so we would need to look at a commercial boiler.
Another plumber has come back and suggested we put in 2 domestic boilers instead. The first boiler is a Worcester Bosch 40 cdi to run the downstairs CH and heat a 300 litre unvented cylinder. The cylinder will provide the hot water to the bathrooms and WC.
The 2nd boiler is a WB 28cdi to provide the central heating upstairs. This will also provide hot water to the kitchen and utility room.
I'd like some advice on how to approach this and what is the likely price difference from a commercial boiler vs 2 domestic ones described above? Does a commercial boiler cost a lot more install, run and service than 2 domestic boilers? Is there any other way to deliver a system other than has been suggested?
Thanks in advance for any comments/advice.
