Aqua Hot Questions...
for a MH "wanna be". We are considering a coach with the Aqua Hot system (I have read the operating manual) and are trying to find out a little more about it, so thank you in advance for any respon...

We have a 2004 Country Coach Allure with Hydro Hot, the smaller version of the Aqua Hot. We have camped for 5 days in 17 degree icy snowy weather without winterizing the coach. Of course you should winterize if you are storing it and not using it. From the manual: "The Aqua-Hot's Domestic Hot Water Heating System must be completely drained of domestic water any time the heater is STORED where freezing temperatures may be experienced.
We have never winterized our coach as we continuously use it.
In the winter we turn on the electric and diesel switches per the owner's manual recommendations (unless we're in a park where we pay extra for electric) then we only use the diesel switch. We have a heat exchanger in the service bay that prevents freezing of the fresh water tank and water lines within the service bay. We fill our fresh water tank and disconnect the water line from the coach if the temperature is going to be below freezing for more than 2 hours. Our Hydro Hot provides "continuous" hot water very quickly. Note: on our coach the demand for hot water overrides the demand for heat temporarily. We never notice this feature because we don't use that much water due to grey water holding tank size. We don't worry about what temperature electric vs diesel. The diesel knows when to kick in. We just leave both switches on. Diesel is the primary heating source for hot water and furnace in low temps and high demand. Electric is a secondary source for higher ambient temps and low demand. We love our Hydro Hot (Aqua Hot). Here is a good website for Hydronic Heater Repair with some photos and info about Aqua Hots. Roger Berke is a great resource.
