Replacing gravity feed HW with combi

[YanisTheYak]

I have an old house with gravity feed HW & pumped CH.

Obviously we have a HW cylinder and the associated airing cupboard. As our house is not particualry large and there are only two of us living there we are thinking of converting the whole system to a combi.

Our biggest concern at the moment is that the old rads will not take the pressure of a sealed CH systems - dose anyone out there think this really is a problem?

The system was installed by myself some years (34 years!) ago and I am not scared of having to some work in order to install a completly new boiler system, however I do not want to have to do the whole thing a new!

Any guidance/ideas on whether a combi (we really would like to get rid of the airing cupboard) or other newer type of system would benifit us would be greatly appreciated.

Please fit a combi and give a heating engineer a job for life. I thank you.

You will be able to muse on the benefit of having no hot water if the boiler does not work one day, and you will not have the agonising decision of whether to turn on the immersion heater (because you won't have one).

It's so much better waiting for the fairly regular call from the heating engineer to fix the boiler rather than the five or six-yearly immersion heater replacement.

There's also the great benefit of someone running a bath or having a shower knowing that someone else is doing the washing up.

You can't do better than a combi
