When we purchased our new motorhome, the sales guy gushed over how we'd love our AquaHot. Having never even hearing the word AquaHot, we learned it would provide "endless hot water"....but we were "ho-hum" about this feature. We noted the cost was an added $11,000 so reasoned "This better be good !!"
We've become big advocates for the system. It's the single best feature, we agree, that is part of our new rig. Not only does it supply endless hot water, but it replaces what would have been a noisy furnace. It purrs warm air from baseboard registers. I used to be awakened by the old furnace turning on in our earlier motorhomes.
I'm 100% enthusiastic about Aquahot and have but one bad story to relate, and I caused it by my lack of understanding. There's an exhaust from the system, about the size of a generator's exhaust pipe. Our sewer drain is close to that AquaHot exhaust and I ran our sewer hose under the exhaust and returned to find it had been melted through by the heat.
The AquaHot makes short order of heating water, warming rooms and destroying sewer hoses.
