Hi,

I'm just about to have an upper floor extension built, which will create a new bathroom. We will turn our existing bathroom downstairs into a shower room and utility area, which is where I want to site a new boiler.

Presently, I've got a Potterton Netaheat for the CH, and a Corvec Britony for the HW. I would like to get rid of both of these, and replace them with a combi. I had planned to install a Vaillant 837e, but then I saw the Aquaplus. My questions are; what's the difference between the two, and will either of them be up to the job of providing HW to a kitchen and 2 bathrooms, as well as heating 10 radiators?

Thanks

Stuart
