96 EVO Posted January 30, 2021 Share Posted January 30, 2021 You do better than the 450D model! After engine shut down, I 'may' get another half hour of the heat exchangers running. By morning, enough warm water for a couple of people to wash their hands and face. Link to comment Share on other sites More sharing options...

Ben, the main reason why you don't get the same results is that the capacity of boiler fluid in the AH-450D model is only a mere 5 gallons versus 16 gallons for the larger units.

96 EVO Posted January 30, 2021 Share Posted January 30, 2021 Yeah. Would love to have a 600D. Link to comment Share on other sites More sharing options...
96 EVO Posted January 30, 2021 Share Posted January 30, 2021 I wonder if anyone makes a lower temp cut-in thermostat that would be a direct replacement for the one AH installs? Wouldn't bother me if the air temp from the exchangers dropped another 10deg, or water temp dropped, before the burner re-fired. No big deal if the burner has to run an extra minute or two, but the short cycling get's annoying! Link to comment Share on other sites More sharing options...
Dr4Film Posted January 31, 2021 Share Posted January 31, 2021 The short cycling is because of the small capacity tank. Aqua-Hot was attempting to save space and weight by making a smaller unit and save money because it was cheaper to make. But the consumer took it in the rear both in the cost of the option and getting a baby Aqua-Hot instead of an adult sized one. Link to comment Share on other sites More sharing options...

Yes we did! I still like it better than propane water tank and furnace(s), but man, I sure wish they had installed 600's in ALL the larger coaches!
