Circulating Pump Method - Distance = 10 Feet or More

This method is used when the water heater tank is more than ten feet away from the furnace or the furnace is on a higher level than the water heater tank. In addition to a circulator pump, you may want to add a aquastat to thermostatically control the pump according to water temperature. This is optional and not necessary if the circulator pump is left run continuously. Another option is a gate valve placed near the pump to control the rate of water flow.

A. Shut off the water heater and the water supply to it. Drain the tank completely.

B. Remove the Temp. / Presure relief valve and discard. Install a short 3/4 in. nipple and tee (1) along with a new relief valve.

C. Remove the drain valve, at the bottom of the tank. Install a short 3/4 in. nipple and tee and re-install the drain valve to the tee (4).

D. Install a circulating pump as shown (6). Run 3/4” copper tubing from the circulating pump to the lower leg of the water coil. This is where the optional gate valve (5) can be installed to regulate flow.

E. Install a 3/4 in. tee and a 150 lb. Pressure relief valve (7) in the top leg within two feet of the coil.

F. Complete the 3/4 in. line by running it back to the tee at the top of the water heater tank. Be sure to install the 3/4 in. vent elbow and automatic air vent (2) at the high point of the line. The optional aquastat can be installed in this line, a maximum of 6 feet from the furnace. This aquastat must close on rise in temperature and must be hooked up to turn on the circulator when the water temperature reaches 120° f.

G. After securing all connections, refill the tank with water and then, ONLY THEN, turn on the power to the water heater.
