The Do's & Don'ts of Hydronic System Design | 2000 05 03 ... Protect indirect DHW tanks from creating convective loops through their own heat exchanger and external piping after that piping has cooled off. A tank full of hot water with an adjacent piping loop is just begging Mother Nature to set up a convective loop. Install a flow check valve to keep the heat where it belongs in the tank. Guide to Heating System Circulator Pump Location & Mounting That is, the pump will work in either location and will move water through the heating piping loop(s). That is because in a hydronic heating system the circulator is pushing water around a closed loop: the boiler and boiler piping are filled with water and there is (or should be) no air in the system. piping a wood boiler — Heating Help: The Wall The info on constant circ. is good but again any diagram on the piping inside with a gas or oil boiler and doing it with a buffer tank involved, mixing valve or heat exchanger.
