Upgrading the house in Sansai and it will include a hot water system (to allow us to bin the electric water heaters otherwise in the shower rooms). Blue pipe of course is everywhere in Thailand. Yellow pipe also, at least as used up here for underground conduit for electrical cable. But this time the pipe is green (and is especially suited to carry hot water, for whatever reason).

Phase 1 was last year but we've since managed to lose the contact number of the guy who did the work then .. so in the hope that someone out there might just have a contact number of a plumber / heating engineer who's qualified to work with this green pipe.

Many thanks in advance.

Seen it on one of my forays in the local HW stores.. I think the SGS thats sankampeang outer ring rd.

I wondered what the purpose of the green pipe was over blue ?!?!

These people can do it for you first class service, would recommend them they did a project from my son

Make sure you use the correct green pipe (the one for hot water also has a thin red line on it).

Did a good job with a passive solar water heating installation for me as well. Be patient with them though... they may not be there when they promise and then take longer than they promised as well. End result is fine, workmanship good by the end.

That may be Aquatherm pipe.....not necessary for hot water systems. Yellow CPVC would be more cost effective and suitable for temps up to 200F, Blue is fine up to 140F. The Aquatherm will likely restrict you to using their fittings...and proprietary stuff is usually better avoided. PEX is about the worst thing to happen to residential construction in the last 20 years. Copper is very cheap now, if you want true quality.

Thanks to all for advice and suggestions.

By way of a postscript, we went down the SGS road and got the balance of the pipe (with the red lines) & fittings there. More to the point we got a contact for a chang / engineer / technician who has since been to finish off the job. (SGS - especially the manager we talked to - were very helpful all in all.)

The technician was efficient, diligent and competent. He also offered unsolicited comment on the Phase 1 work which had been done previously (and which was on hold pending our other upgrade work in the hong nam). It wasn't complementary and we agreed with his assessment. (The quality of the pipe, for example, was very different, meaning inferior.)

The people who supplied and fitted the Phase 1 work were a well-known national home improvement chain. Their quote for the phase 2 work was 16.5k. We ended up paying less than 5k for materials, channelling & fitting. And we gave most of the the work and money to a local guy (who was very happy with his generous payment).

So self-help through a forum like this does work, as does shopping around. Cheers.

Where's SGS?

"I think the SGS thats sankampeang outer ring rd." as per the above thread. Big place on the corner at the traffic lights junction where the Sankampaeng Road cuts the outer ring road.
