I have an outdoor wood furnace that is piped with a side arm heat exchanger to heat my hot water at the hot water heater. I have softened water also.
The exchanger is piped with a tee at the hot water heater bottom drain and then up to the top with a tee and 4″ brass nipple at the original anode location. The anode is threaded into the top of the tee with the thermo-syphon from the exchanger at the side of the tee.
My problem is the anode will corrode and restrict the thermo-syphon flow and thus no hot water.
I am contemplating the use of the powered anode. Will this work? Are there concerns with the anode not sticking far enough into the tank to protect the overall tank? Any other concerns? Thanks in advance for the help.
I’d like to see a picture of the anode/tee assembly, but I think a powered anode will work. You’d have to use a galvanized tee and PEX-lined nipple, but the electrode comes coiled up and you stretch it to the depth of the tank, so that part isn’t a problem.
