Whilst I like the heat only what you need aspect of a combi, which
hopefully saves on the fuel bill, we use economy 7 to heat the
cylinder overnight. We would lose this feature with a combi. I
thought that economy 7 was cheaper than oil for heating water? It
also gives us a back-up system so that if the boiler breaks, we
still get hot water. So I think we would like to stick with a
regular boiler this time.

I am not sure if economy 7 is actually cheaper. If you need backup
insert an instant electric water heater in the combi line - about
£100.
The DHW runs though. If the combi is down then turn on the water
heater. Gives a get wet shower and one tap for backup.

And if the combi needs faults seen to that include the water supply
to it?

Please eff off as you are a complete plantpot.
