We are just renovating a house and have already ripped out the old surface mounted iron pipes of the central heating. We would like a new combi boiler and don't really have room for a cylinder. The water pressure is pretty good so thought a combi would be ok.
The problem we have is that I don't know how much output we need of hot water. We will have one bathroom, one shower room and obviously the kitchen and washing machine will need hot water.
I think I have narrowed it down to two that have a high output (both with internal stores) - the Vaillant 937 or Alpha CD50. I am leaning towards the Vaillant at the moment.
Can anyone tell me if either of these are any good or if there is anything else they can recommend instead?
Combis are entirely suitable for family homes where there may be a large hot water demand,and Vaillants are a very good make of bolier, possibly the best although Baxis are also very good. Alphas are very good but not quite up to the same standard in my opinion
