Thanks you all.

The Aqua Hot system is powered by either 120 volts or Diesel. You can have BOTH at the same time. 120 volts is used for Furnace type heating thru floor radiators with Muffin fans. Diesel is required for CONTINOUS HOT WATER production like taking a shower. the 120 will heat about 1 gallon on hot water for hand washing and small amounts of hot water. BOTH 120 and Diesel have Tstats in the boiler tank to shut the unit off when the preset temp of the boiler is reached. So, I guess your question about 100 degrees was about HOT Water production which the Aqua Hot will run to heat the water. As to 100 degrees for furnace operation, nobody would want to use furnace over 100 degrees:@ IF you are looking to buy used, you are best to have a Aqua Hot trained Tech check out the system. They cost over $6k up to 10k depending on the model. ALL parts except the boiler tank can be replaced. If the boiler tank leaks from a crack(usually freeze damage) the unit must be sent back to Aqua Hot for repair or you buy a new system. Having the CORRECT GLYCOL in the system is a MUST. It is NOT regular automotive antifreeze. This is something a qualified Aqua Hot tech would test and verify. Doug

Listen to Doug, he's spot on. Also, check the filter and reservoir. They can be found on the roof of one of the bays. Know where they are if you buy the coach. Do not use antifreeze....Dennis

Agreed, something doesn't work on his system. Exhaust should be clean with no oil. Each heating zone involves a pump and fan on the inside radiator plus thermostat and controls, make sure they work. Mine has a cold engine heat zone. Mine also heats from a warmed up engine.

These units are complex and VERY expensive and the typical propane heater pales by comparison. It might pay you to have a mobile guy check it out.

If the seller then he knows there is a issue with it. Go by the model # and download a manual. Temp does not matter. They are pretty much the same.
