Plumbing Specification Help?
I'm in the middle of my loft conversion at the minute. I was going to pressurise both the central heating system and the hot water system to allow me to extend the c/h into the loft and provide h/w to the en-suite, but by the time I'd priced up all the kit, and the complexity of doing it myself, I'm thinking I might as well change to a combi!
I've written the following spec, which I'd be grateful if any of the resident plumbers could have a read over and make any suggestions as to errors or omissions? Before I invite a few firms to site visit / quote.
Cheers
