Thanks to everyone for the comments and suggestions.
A large combi *sounds* like a good idea, but my own experience with them warns me away from them.
Thanks, BraileTrail

A small instant DHW electric heater can be installed as a "backup", give 5 litres/min. It can have a heavier cable if required. People will go for it. Pay attention.
G'wan, make it 3 just to be on the safe side. Sod's law says the backup will be bust when you need it.
I would assume you would have to.
That is like say I bought a cheap crap car and it was bad so all cars are bad. Buy quality.
You can go on and on. Do some calculation on pounds and a second small cheapo backup combi is very cheap to do. It gives FULL backup. Never thought of it did you?
This one is learning.
Nice one:-)
The Saunier Duval engineer whose house I did some work in did indeed have two boilers in the loft. One was for backup.
The back up was a Baxi.
