I would add is that for a system that can deliver 2 simultaneous
showers worth of water you will have to go for a more expensive type
of thermal store, as the simple cheaper ones (such as via Navitron)
cannot deliver.
Also you will be restricted by the number of plumbers willing to
install this type of system.  I couldn't find one in south Suffolk :-
( so went for a conventional main pressure system.
Note the thermal store will almost certainly be mains pressure, esp
if you have a system boiler. If you want to avoid mains pressure tank
at 80-90C you need to match the heat sources and tanks coils etc etc
v carefully.

Its nice to hear Broag get a good writeup, I've just had an Advanta
Plus fitted. Do you know if the 0-10V input applies?  I didn't find
the consumer facing web site too helpful.
