There is a toggle switch in the bathroom with, "Continuous Hot Water" on the label.

We have a Hurricane Heating system, but how would it fire up if our heat isn't on? Do Aqua Hot systems have the same thing?

Does this continuous water go through the HW tank, or some other path?

Finally, why would we want continuous hot water?

Take a long shower to find out why!
My 600D AquaHot will supply continuous hot water but only if I turn on the burner. Even using both electric elements won't do it.
They also make a 675D AquaHot that is 240 volt electric elements and diesel burner. Even it will not supply continuous hot water on only electricity.

Speaking to Aqua Hot system (not sure about Hurricane). Heat and hot water are two separate things, from the same source.
Simply put, Aqua hot is a boiler that contains a coiled water line running through it. The boiler fluid is heated and the heat is transferred to the water. Since it is very hot, especially on diesel you have continuous hot water.

Continuous hot water is meant for long showers - most RVs have only six to 10 gallon heaters and are good for a relatively short shower before you have wait for more hot water. Aqua Hot turns on, heats the boiler fluid and provides fast heating to the water running through it so it stays hot.
When I turn on my Aqua Hot it heats the water rapidly on demand as it flows through the boiler. If I turn off the tap it shuts off shortly.

When I want heat, I turn on one of the three zone "radiators" (front, bedroom and/or bathroom). Aqua Hot kicks in a burner (or electric element) and fluid from the Hydro hot is pumped through the lines to each radiator (and I will also have hot water if I want it). The Aqua Hot is controlled by my thermostat.

I normally have my Aqua Hot in electric mode and only fire up the diesel when the wife and daughter are having showers.

If your heat is not turned on, you will not get any heat.

If AquaHot is radiator heat, Hurricane is forced air heat. From what I'm reading, it would seem that the switch on the bathroom cabinet might fire up the diesel burner and heat water while not turning on the forced air blowers.

Can anybody verify this? With only the two of us, we've not run out of HW (yet) and I wouldn't want to mess with our Hurricane system when it's dropping into the 30s here in TN.

In the Hurricane system you can heat water two ways depending on model, one with the diesel boiler only and another with a electrical element along with the boiler. Sounds like you have the ability to use an electrical element along with the diesel

Hurricane units are from the marine division of ITR which also makes the Oasis hydronic system (aqua hot competitor) that Newmar uses.
You may be able to find your manual in the link below, or give them a call. I've heard that their customer support is very helpful.

To clarify the Aqua hot system does use a fan over each radiator to force the hot air out - so it is not a radiator heat in the sense that older homes have. Hurricane also uses this same method and refers to this as heat exchanger fans. This being said, there are several options on how the heat is transferred.

Most MHs without an hyrdonic system do use a true forced air furnace that heats the air in a burner and blows it through ducts throughout the MH. It is separate from the hot water tank.

AFAIK all hydronic systems (Hurricane, Aqua hot etc) use radiators (heat exhangers) throughout the MH usually with individual fans pushing air over the radiators. It is part of the hot water system and referred to as a hydronic system.

If you turn on continuous hot water you will not be turning on any forced air blowers but will turn on your diesel burner. It will not pump hot fluid to your heat exchangers so will have no effect on inside temperature.

Your heat is separately controlled by the zones and setting in your thermostat. If you need heat, set the thermostat to the appropriate setting. This will instruct the Hurricane system to turn on pump hot fluid to your heat exhangers in that zone.

Good to know, and logical. Right now the system is cycling about 2 minutes ON, then fan continues for 2 minutes, then it repeats. Very even heating and is capable of (at lease) increasing interior temps to +35 over outside temps.

We'll wait to get home before trying the continuous function, since our 10 gallon water heater is doing just fine (electric normally, and LP when breakfast is being made so we don't trip the 2800 Magnum again)

You hot water tank has a heat exchanger that takes hot water from the Hurricane loop and heats the hot water. There's an aquastat that senses when you are using hot water and will fire the Hurricane when needed. The remote switch must be in the ON position for it to do so. I find most of the time we have plenty of hot water in the tank using the electric element for two of us to take a short shower. On occasion we treat ourselves to a long "endless hot water" shower using the Hurricane boiler. I really like our Hurrance unit.

Can any of these systems be added aftermarket? I've got the typical forced-air LP furnace and like the idea of a diesel-fired heating system. I was thinking of adapting a diesel forced-air heater that trucks or buses use, and connecting it to the heating ducts under the existing furnace (there's space in a compartment) but I also have LOTS of space in my wet bay if there was a way to install one of these units instead...
