Underfloor heating

[ecogeorge]

Can anyone recommend either a book or source of information for DIY underfloor heating installation.
I have agreed to help my brother install his (GSHP Installed) and although once installed my own  -it was very much a trial affair. It does work well but wondered if there is a source of good info anywhere.
Looked on amazon and fleabay but books had poor reviews.
thanks in anticipation
George.

How about the polypipe or polyplumb website? I think they have calculators and guides, don't get bamboozled into buying all their expensive "Proffesional" products though, you can do much better by buying individual components from a plumbers merchant.

It is a lot simpler that many people make out really.

hello,

some basic information here

- http://www.johnguest.com/wp-content/uploads/2014/07/UFH-Tech-Doc-Z2105-387-0914WEB.pdf

- Pex-Al-Pex seems to be the favourite among the DIY community though you are restricted to 16mm fittings, there are 16mm to 15mm adapters available

If i remember correctly  BOSTA  did 16mm to 1/2' BSP which fitted my manifold.
Thanks for link will look at tomorrow ......

I just got a kit from Chelmar heating. They did the design and supplied the parts and left the rest to me. Think I did some sums at the time and it had not cost a lot more than buying the parts separately. Sure they get bulk discounts but this was some years ago so they may not do this now.
