I would like to use my old gas boiler as freeze protection for my 500 gallon water storage tank, which will be normally heated with a Biomass40. Does anyone have any idea for to make the gas boiler run only based on storage temperature? Would a clamp on aquastat, fed with 120, then onto the circulator pump work or would I need some form of thermostat at the tank?
The gas boiler is tied into the lines between the tank and wood boiler. I would be using this only in emergency (like anb accident prevented me from firing the stove).
Thanks,
Bill
