The AquaHot system is a very good system. Ours has serviced us well over the years. Several recommendations: 1. The tank in the compartment is never 'full'. It's an expansion tank that fluctuates. To be full, look for the mark on the tank itself. Full in never full to the top. There should be no screws in the tank. Sounds like a 'redneck fix' for a leak. Replace the tank. Also the AH system should be serviced regularly. Easiest way to check is to fire it up and check the exhaust. A proper running system should not emit excessive smoke and/or smell. The key word there is excessive. AH recommends new nozzle every year. My AH technician recommends service every two years, but he's serviced mine since it was new. He replaces the nozzle, checks the interior and also checks the fuel pressure. If you're tech does not know or have the tools to check the fuel pressure, get another technician. It's simply a boiler system that's diesel fired. BOL on your purchase. If you do buy it, I'd insist on a 2 year extended warranty, paid for by the dealer...Dennis
What doesn’t make sense is you are the second person to say that tank is not supposed to be full. But the screws were 2/3 of the way up and leaking so that tells me the tank not only had to be 2/3 full at “some” point, but also because the screws and the streaks are rusted, consistently 2/3 full as well and not sporadic or not just at “some” point.
Does that indicate maybe some kind of a malfunction with the tank filling up more than it should because of a blockage somewhere like a clogged filter? Sorry but I’m thinking like a plumber :)
