Is Aqua Hot retrofitable?

They make a LP one and if you use the smaller heat exchangers at around $200 then you can stay under the $8000 if you do the work your self. I help a neighbor and we ran Pex and everything was working with in the week. Not too hard, but not a walk in the park. I think it would have been about the same to use the $500 heat exchangers and not have to run as many runs. They spent the winter in Montana and stated that it work.

After having one, I'll never have another coach without an Aqua-Hot. HOWEVER, I cannot imagine the cost and effort involved in doing a retrofit on a non-AquaHot coach.

Yeah, I didn't realize how pricey this unit is. My furnace is just fine, I think. It would be an expensive hot water heater:D

maybe Roger Berke www.hydronicheaterrepair.com will know and provide info. I call him the Aqua Hot "guru"

running the lines for the heat exchangers would be a HUGE job

Probably cheaper to trade your RV for one equipped with an Aqua Hot.

Hi,

Yes, you did, but so did I for $37k.

A used unit will cost anywhere from $3-5K.New units are in the $10K range. Then you need the registers (my 40ft has 4) at a cost of $500 each. If you don't burn diesel than you need a tank for that. Add some bux for hose and you are all set.

Here is one route. Replace the existing water heater with a "motor assist" unit, that has a 120 1500 watt element.

Add a circulating pump.

Run "zones" to the areas that are to be heated with thermostatically controlled valves.
