Aqua Hot ...or Not

I'm still building my list of "must have" and "should have" and "don't need" as I research DPs. Frequently come across Aqua Hot as an option and I've read the literature. The question is to those who have/had AquaHot ...is it an option worth considering .... and why? Thank you muchly

I wouldn't have a motor home without it. There are several threads in this forum that discuss the pros and cons it you do a search but I will do a quick point form pros.
1. Gives nice quiet dry heat compared to propane type furnaces.
2. Has electrical option that allows cheap heat when plugged into shore power.
3. Uses heat of engine when driving to heat MH.
4. Can be used to preheat engine before starting on cold mornings.
5. Gives you unlimited hot water for long showers.
6. Water heated while driving giving you instant hot water when stopping. Usually stays hot for quite awhile depending on the amount of usage without firing up diesel burner.
7. Burns diesel from your main tank so if boondocking you have a large tank of fuel to draw from.
The AquaHot does require a bit of maintenance and have to be winterized properly but I dont feel that either of these cons outweigh the cons. IMHO

Have been on the road full time since 05 and had Aqua/Hydro hot in our first MH and currently have Oasis (same thing) in our current rig. Should this be on you "must have" feature list???......your call, but.....in our opinion.....ABSOLUTELY!!!

Now, having said that.......you WILL get all kinds of differing opinions. Only YOU can make the call.

I had 3 DP's without and current one has it. You can live without it, propane furnaces work well but are noisy, heat pumps are OK, just not fast, Aqua Hot is instant and quiet. I am personally never buying another coach without it. The one disadvantage (have not experienced it yet) is the diesel fume smell for neighbours when the system is running.

First of all I would agree 100% with what DC Cruiser had to say.

I have a friend who was a very successful salesman for LazyDays RV in Florida and had a wealth of knowledge about Motorhomes. We were talking about my search for a used DP. At the time I was looking at Country Coach, Monaco & Newmar. The subject of AquaHot came up and he told me that it would be a must have option on whatever I ended up with. He said that the dealership had been forced to wholesale several
coaches, similar to what I was looking for, due to the fact that they did not have the AquaHot system.

When I first got my current DP I had some problems with a thermostat on
the AquaHot. It was very easy to replace. The unit requires an annual maintenance which consists of changing the fuel filter, a fuel nozzle and cleaning the combustion chamber. If you are at all handy you can accomplish this by yourself.

Good Luck


PS Coming from Illinois I really like the engine preheat feature

And its size: the one little unit takes the place of a furnace, water heater, and propane tank (if you also get an all electric coach).

Make sure the Aqua-Hot unit opens toward the door so it can be easily accessed for maintenance.

No fumes if burning properly. Free heat while rolling down the road.

If your unit does not have one now it would be a little difficult and very pricey to install. It would require an available bay. The cost from the factory when they install it is around $12,000 +- . Installing after the fact could be several thousand higher.

Once you've had an AH, you'll never go back to propane furnaces. Based on what my dealer said, $12k is high for one installed.

I like it but it is an expensive option we have had 2 coaches with it. I would look at how much you plan on using the coach and see if you can justify the expense.

Since we follow the 70 mark (or at least try to), this has never been one of those things that we've felt we should have had. Our propane furnace runs maybe once or twice on really cold mornings, otherwise the small electric heaters take care of keeping the coach warm. If we spent more time in cool climates then maybe it would be something we would be sorry we didn't have. Do know that several friends have had troubles with theirs and the repairs haven't been cheap.

I totally agree that it's not mandatory as a heating system if one stays in temperate climates. But the reason we love our Hurricane (another company that makes a product similar to AquaHot) is not because of its heating ability, but because it provides unlimited hot water! Long, hot showers with no concern about whether or not someone else needs to use the shower. As the ad says, that's PRICELESS!
