Hi All,
We have had a Main Avon Thermostatic multipoint 'water otter' (heater ) for at least ~15 years now but I think it's had enough (leaks from the gas / water control valve piston (repairable) and possibly also the heat exchanger core).
Our neighbour had a newer, de-commissioned Main Mersey Super hanging on the wall (and hence my brick question previously) and has given it to me with the idea that it *might* (should) be a fairly easy swap, coming from the same family etc.
The real question (other than would anyone actually know if these two will share a common flue?) is how differently will a non thermostatic model work in practice? i.e. is it still 'thermostatic' but just doesn't have a user adjustable temperature setting or will the water temperature simply be a function of the water flow rate ( moderated by the sink / basin taps etc). If it is the latter then I guess I could set a minimum temperature by limiting the maximum flow rate somewhere?
All the best ..

p.s. We don't have central heating but do enjoy having continuous hot water (even during a power cut ).
