PEX 101: Is PEX OK for hot water?
PEX has long been used as a very reliant pipe for residential and commercial use. PEX also has become the number one option of contractors in the heating and cooling industry.
WHAT IS PEX?
PEX—short for Cross-Linked Polyethylene—has been gaining popularity in both the residential market and commercial sector. PEX pipe is made from cross-linked HDPE (high-density polyethylene). The HDPE is melted and continuously extruded into a tube to form a high-performing pipe suitable for a variety of potable and non-potable plumbing applications. It has also been overtaking copper and CPVC because of its flexibility compared to copper and although PEX might freeze, unlike PVC, it would not burst.
It comes in different colors–red, white, blue, white, and grey. However, there are no performance differences between these colors and all are intended for use in potable water systems. The colors can be used to easily distinguish between hot and cold distribution lines.
IS PEX OKAY FOR HOT WATER?
PEX is totally great at handling hot water! PEX does not melt (analogous to elastomers) and is thermally resistant. The maximum heat temperature of the PEX tube is 200 degrees. The maximum heat of the PEX can be up to 180 degrees. The PEX tubing has the highest temperature limitation listed in small prints.
