Watts Radiant Onyx Tube

your Wirsbo dealer will have all that information at his fingertips. They are the industry leader for a reason. I am curious as to why you prefer Onyx. Wirsbo's installation handbook has what you are looking for.

PEX -a is the only way!

    Watts Radiant Onyx

    Hello, I am looking for info on 1/2, 5/8 , and 3/4 Onyx and the amount of baseboard which each size is able to carry along with max tube supply & return. We would use either a 007 or 008 circulator and our baseboard puts out 600 btu's at 180F/4gpm. Thanks in advance.
