Got a problem which some of you may have had some experience with. (assume most of us are alternative energy lifestylers)
Got a 300 ltr Solahart hot water heater with a small leak. I bought it second hand 10 years ago from a cousin and installed it myself. Before installing it I removed and cleaned/checked inside the tank by removing the large flange plate at one end of the tank. The sacrificial anode was cactus so I replaced it. Whist doing this I noticed the anode had dropped and come into contact with the tank damaging the enamal finish. I suspect this is where it is leaking and it is only a pin hole.
Replacing the tank is both expensive and a pain as it weighs 50 kgs and is on the roof. If I remove the end flange what is the best material to put on the enamel to cover the suspected pin hole? Araldyte, epoxy or silican? Probably think the araldyte is the best way to go. Only trying to save some money and get another 10 years out of the tank.
If it were a cheap instant gas heated tank I would not bother but the solar/electric heating is not as concentrated and the tank is stainless with a heavy enamel covering.
