I used the brass for all. Would you put pipe insulation on it?

Pex makes special tubing just for heating. Check out their web site. Good Luck, TomC

That's what HydroHot sent me when I bought the self-install kit. High-temp PEX and brass fittings

Hi Eric,
It's just called "Heat Pex" it has an oxygen barrier and is good for temps to 240geg. Not much more money either..
Try and stick with 3/4" or larger. Especially if you build a manifold because the pumps in Proheats and Webasto's are
not as powerful as conventional/home type circulator pumps. They are magneticly coupled together and tend to
give you slipage under a strain.
Good Luck

I am just getting started with the PEX, haven't seen brass crimps, I have the copper ones. Are these the same or am I missing something, haven't seen brass?

Ray, the crimp rings are copper or stainless, aluminum was available for a while but they have been taken off the market because of to many failures.
I use the stainless crimp rings with Watts brass fittings myself
good luck

Saw an interesting version of what I think was Pex on "This Old House". It was three layers. Two plastic with thin aluminum in between. You could bend it and it would hold it's shape. Have not worked with Pex but it looked like it might be easy to work with.

I used pex for the radiant heat in my house. 20 years so far no problem. Easy to work with.

Thats what i'll use then. 5 zones including the dash heat. I am going to use the engine coolant system as the expansion tank. I have valves to take the proheat off line if I have a problem. Good bad idea?

Do you guys use fittings for every 90 bend? Trying bend 90's with that stuff is like fighting a damned python and you need a boat anchor to hold it in place; well almost.......

I am not familiar with this kind of heating in a bus conversion. Do you put it on the floor directly, and then install a new floor over the top? What kind of floor can you put it on? What kind of flooring material can go over it?
How about in the lower wall below the windows? Would that work?
Thanks

A friend of mine just did his whole house with the Pex, including all plumbing, radiant in floor heat and even in floor heat in the garage. I would suggest you visit some Pex internet sites and read into radiant floor heating before you install it in a bus. There are many different ways to secure it. NO you do not want to put fittings in the floor and then have it covered. If you should develop a leak all your plywood would become saturated with your antifreeze solution and it would never dry up. Could be a very expensive and labor intensive learning lesson if not done correctly.

Some kinds of PEX are more flexible than others. The brand I bought for my fresh water plumbing is quite flexible. I used Flex Pex.
