HydroHot Fuel Consumption

How much diesel fuel does a HydroHot use?

While it is capable of 0.4 GPH, that is full 60 minutes non stop heating. That never happens, more like less than 0.1 GPH. Additionally you are plugged in and should also be running your electric element (1500 watts) as well. This further reduces the fuel consumption.
Now when you pull out of camp and have been running your Aqua Hot, leave the settings and furnace in the on position for each zone. Turn off both the electric and diesel heat switches. Now while you drive the engine will mildly maintain the heat (this is equal to about 1500 watts of heat as it is a coil that runs coolant through the heating anti freeze.) You will find the fans running with warm air for hours after leaving camp. Enjoy.

My last coach would cut the generator out at 1/4 tank or less. I presume the DSDP does the same.

Does the HydroHot also cut out at a 1/4 tank?

The generator does draw on only the top 3/4 or so and I would think the Hydro Hot draws from the same intake, but I'm only assuming that.

Hi Peter! That has to be one of the best tips I have learned from you so far! Paul

Jetsmania, Of course I ment Hydro Hot not Aqua Hot, though may be it works the same. We can all learn from each other as there are so many options and feature with a variety of configurations.

This feature is called "Motoraide" by Hydro Hot. It functions on both models whether you have the 200 w/engine heat assist or, like me, the 500 w/o engine heat assist.

java, you are correct and as Peter has corrected, we have HYDROhot and not AQUAhot...

I was told the difference by Ken Miller of Newmar's highline service and will try and describe what he told me without screwing it up...

Seems the AQUAhot is a bit larger and thus has a valve that prevents the heat from taking the hot water from you if you're in a shower.
The smaller "HYDROhot" has no such valve,thus when the shower calls for hot water,it "may" interrupy the heat a bit....Ken said that this feature isn't a real big deal,given the fact the call for hot water isn't that long and the coach temp wouldn't "really" be affected for that long.

ALSO....the London Aire has a totally different system that works similar to the Aquahot,it's called an Oasis Heating System.

(He's obviously never seen the time my daughter takes in the shower with her hair...)

How'd I do Peter?

The Hydro-Hot is our smaller system designed with Motorhomes with less ample storage space in mind. Almost as powerful as the
Aqua-Hot, the Hydro-Hot will still provide you with unlimited hot water and quiet, uniform interior heat.

Google is a wonderful thing!

In our shakedown cruise, my wife had the pleasure of taking a shower after mine and the kids baths, and doing dishes.

The hot water pressure actually fell. Cold water pressure was fine. I had figured the HH had "fallen behind". I had her turn off the shower for 20 seconds, turn it back on and she was fine for the rest of the shower.

Great Bob, thanks for the info on the models.

Also...from their "How it works" page...

Hot Water: Our heaters are designed to provide an unlimited supply of hot water through a tankless,
on-demand hot water system. Domestic water is heated as it runs through coils located inside the heater.

Interior Heat: Our hydronic heaters are similar to a home "boiler" system. Whenever an interior Room Thermostat "calls for heat", the heater's hot water solution is then circulated through interior heat exchangers (similar to radiators) located throughout the motorhome. Because our system has multiple circulators, it can circulate heat to independent interior heating zones. Our heat exchangers are designed to gently disperse heat quietly through low velocity fans.

Engine Preheat Loop: Our system is equipped with an engine loop which circulates the hot water solution through the engine to warm it for easier starting in cooler climates. This same loop also utilizes the engine's heat while you are driving.
