Can you run PEX tubing in hot water?

The big thing is they will not run as hot as a boiler. However, running pex tubing in concrete doesn’t require the water to be as hot as perimeter or radiator hot water heat as long as you leave it on long enough to heat the concrete up to operating temperature which will take longer.

What is the maximum temperature a PEX can withstand?

The PEX tube is intended for hot and cold potable water distribution systems. The PEX tube can withstand a maximum heat temperature of 200 degrees Fahrenheit. In a plumbing project, the PEX is able to stand a maximum heat of up to 180 degrees Fahrenheit.

Which is better for a hot water tank PEx or copper?

PEX fittings can be expensive. However, long runs of PEX can usually be done as one piece, while copper needs a fitting at each bend. Because PEX is flexible, it’s less likely to fail due to freezing or earthquake, compared to rigid pipes. It’s also way cheaper than copper, which is attractive.

What happens if the Pex fails on a water heater?

As @Michael points out, a T&P safety valve is rated to go off at 210°F (100°C), so if something does go wrong and your water heater overheats, there is a possibility the PEX will fail. If the PEX does fail, it almost certainly will happen right above the tank (which will be the hottest place, obviously).

Can I use PVC for hot water?

As mentioned before, CPVC is more suitable for hot water applications up to 200F. PVC is still often used for unheated water as well as for vent and drainage systems; however, CPVC has become widely used for both hot and cold potable water.

What is a “heat loop” at a water heater?

A hotwater loop keeps heated water close to the faucet at all times by circulating cooled water back to the water heater to be reheated. There are three basic ways to create a hot-water loop. The first and simplest method is installing a small pump on the hot-water line at the point of use farthest from the water heater, usually a bathroom sink or shower.
