According to RPA Standard Guidelines, recommended circuit length for 1/2" PEX tubing is 250-350ft, depending on the application and type of installation.

For snow melt applications, use larger PEX tubing sizes, such as 5/8" and 3/4".

Works great
Can't give five stars because it is the only name brand of pex that I have used. 3/4 and half inch both marked every 10 ft, I believe. I put appox 1400 feet in wood using aluminum plates. I also did 1400 feet in concrete by stapling it to 28 lb foam insulation using the staple gun that I bought from here. Love it.

I love Everhot pex tubing
1/2 inch was easy to work with. I have used both 3/4 and 1/2 inch. My wife just loves the warm bathroom floors on these colder mornings.

Why let the local plumbing store order this when you can order it, free shipping, and a 1/2 the price? I am sure it arrives at my home quicker than ordering it from the local store.

Good stuff
I just got pex laid down and covered with concrete. Laid down good and survived the pour. Seems to be well made pex pipe. Hooked up a temporary manifold and pressurized before and during concrete pour, which I would strongly advise. If there is any leaks it will so up right away.

Very professional and item arrived as planed.
The PEX radiant tuning arrived like they said. The price was less expensive then others out there and the warranty is the same as the most expensive out there. Ram all the PEX and will definitely order again from them.

Great product, great price!
I checked the local stores & PEX Universe had it for half the price they offered & available in more lengths. The product is as easy as it can be to work with for something that's spent it's life coiled up in a box. The length markings printed on the outside are nice to have & the tubing can be written on with a permanent marker for identification.

Good heating tube,
Easily workable. Bends in short radius. Quite sturdy. My only complaint is that it is quite stiff below 60F. (It was 55F when we did the install and we kinked it a couple of times) But just bring a heat gun and everything is fine.

a good way to buy pex tubing
for radiant heat in the floor. So far it seems good but the real test will be later after I have the system installed in entirety

Good price
"I bought 9 rolls for a basement slab. It seems to be okay. I installed everything and it tested to 100 PSI overnight. The price is great, I sure hope it lasts my lifetime. The description didn't say, but mine had length markings. I was using a full coil per loop, so I didn't check all rolls."

I would buy this product again.
In floor thin slab. Product went down pretty well. Bends of 7" to 8" radius OK. No leaks.

Can Oxygen Barrier Pex be used in an open radiant system?
Helpful? Yes No
Only if it's non-potable. Only Everhot non-barrier PEX is approved for potable water applications. Moreover, there's no need to use oxygen barrier pipe in an open type system since it will have a constant supply of oxygen rich water, rendering the oxygen barrier useless.

How much 1/2 pex will I need for a 200sq ft room?
Helpful? Yes No
The short answer is that a 300ft roll is sufficient to cover the space and should leave at least a few dozen feet. The detailed answer is that length is determined by the spacing of PEX tubing OC (On Center): For 12" spacing: multiply x1.00 For 10" spacing: multiply x1.17 For 9" spacing: multiply x1.25 For 8" spacing: multiply x1.34 Always remember to add the length needed to connect both supply and return lines to the system/manifold.

Can the O2 pex be ran in the ground 25' to connect to the water heater?
Helpful? Yes No
Yes, given that the pipe is properly protected from freezing temperatures (insulated if needed), abrasives (rocks, pieces of metal, etc.) and rodents where applicable.
By PexUniverse Customer Service on 06/10/2015
How much 1/2" pex tubing is used to make a 180 degree bend when the tubing is spaced 1 foot a part. Thank you

The bend only part is about 18-19".
