Are you saying it will be to big?

Will the 938 be able to supply 2 showers at the same time?

Thanks

All down to water supply,keep the unvented cylinder and get the correct output boiler is the best option

Don't change to combi. Assuming the exiting has worked okay

as others have said dont change to a combi, keep the unvented cylinder and a properly sized boiler, highly unlikely you will need 38KW

Thanks everyone, will stick with the cylinder.

How does this quote look to everyone???

Why are you changing the cylinder?

From the pic the cylinder looks very nice! Any particular reason you've set your heart on a combi? Not always the best option, as discussed on this forum a number of times.

You've mixed me up with someone else, I haven't got my heart set on a Combi.

What do you think I should have???

I haven't got my heart set on a Combi.

Unless I'm much mistaken, the Vaillant ecoTEC plus 938 38kW is a combi. Also the 38kW. 18 rads sounds like a biggish house (depending how big the rads are) but highly unlikely to need 38kW. Combis have high power due the instantaneous hot water demand.
Other posters have suggested different approaches.

I've decided on a boiler and cylinder.

Do you have any advice on this?

3 bathrooms 18 rads.

The OP has a quote for a Vaillant ecoTEC plus 637 which is a system boiler.
