Choosing depth of proposed hot tank for hydronic system
My hot water will be recirculated from an underground insulated potable water reservoir heated by closed . loop on wood heat gasifier. The potable water tank location im considering is at a depth of 50 feet below ground. Should i be concerned with fighting gravity/expense on this proposed depth ? Or does the depth apply on a closed system ? I do have another option to sink a seperate reservoir outside of bunker if depth of water body is too costly.
