Heating Zone for Every Room?

[Boatist]

Hello all.

We are currently building an extension on our house and will have a 4 bedroom house when it's all done. We've never had central heating, so as part of the project we're putting a brand new heating system in the whole house. We want to do as much of the work ourselves as we can, but could really use some advice...

I have attached a drawing of what I've dreamt up and would really appreciate some comments. We had this (maybe mad) idea of having 8 heating zones in the house, with programmable room stats in most rooms, and some smaller radiators on TRV's. Different parts of the house get used through the morning, day and evening so multiple zones would work well for us. I've done bits of plumbing before and electrics are easy for me, but there's a ton I don't know here!

Will the pump in a combi boiler cope with this system? Can I really do that with the return pipework!? Will the extra pipe losses make the whole thing pointless? :crazy:

Thanks so much for your help!

I hope this attachment works...

having reread your op, forget aga and boiler and bung in a rayburn 480 or bigger, built in boiler and separate cooker section , much more efficient than an AGA, cheaper to run than your other optins, unvented cyl available on it as well, and keeps house nice and warm at same time. cheaper to install than aga/boiler combination
