[QUOTE="mcantrell71, post: 6849285, member: 732997"] [B]TL;DR Summary:[/B] hydronic heat transfer calcs ?? Looking to build a suitable closed loop water (probably glycol mix) circulation system to prevent livestock water troughs from freezing. I assume that I need to calculate how much heat loss is predicted from the water tank in ambient air (varies, but assume worst case), then what length of heat transfer pipe will be required to be buried in stable ground temp (55 degrees?) to supply the necessary Btu's. The plan is to have a solar panel with battery to power circulation pump. 1/2" PEX. 0.675" OD, 0.070" wall ground temp - 55 F ambient - 0F 100 gallon trough uninsulated (for calculations) 0.5 - 1.0 gallon/min pump THANKS FOR ANY INSIGHTS!!
