    Snow Melt Water Temps

    I have a small snowmelt system for our sidewalk out fron. What sort of water temps should I be seeing across the system, supply and return when it is operating during a snowstorm???

    It depends...

    It really depends on the design. We just did one with 3/4" pex at 9"oc. We used 2" blue board and centered the tubes. It runs really well at about 100-120. I tried it hotter and the heat was uneven. Lower temps also put less thermal stress on the concrete.

    wow!

    I've been running at 90 and was afraid that was too high. I have it set down to 80 as an experiment. I'll let you know how it flys.

    temp

    90* is the normal design temp for snow melt. Too hot and you will damage the concrete.
