I've a dilemma which I am hoping to get some independent advice on, particularly from those of you with MBC builds!
MBC have provided us an option to lay the underfloor piping and Trish has supplied us with significant detail on the specifications (16mm Pex-Al-Pex, 100mm spacing, contraflow layout etc...). Layed out on top of EPS (seperatly supplied by us!). All for a reasonable price (so we think).
When we asked a heating system supplier to remove the equivalent from their quote we got a lot of warnings:
- spacing may be too wide
- does the pipe have an oxygen barrier (does Pex-Al-Pex?)
- are they using cheap DIY push fit couplers and bends
- unnecessary pumps, valves or actuators
This has given us pause as I don't think I can answer any of these even after several hours of research.
I'm tempted just to DIY the lot, but it then starts to run into the design and specific of DHW and heating systems which I've no clue where to start.
Any advice or pointers to articles or posts that'll give me a decent start?!
