A warm floor on a cold morning, a warm shower after a long day, these amenities are a couple of the primary reasons some people camp in motorhomes rather than sleep out under the stars. Typically, a traditional RV heating system depends on a couple of things: one or more propane furnaces to heat the interior and an electric and/or propane hot water heater. The Aqua-Hot hydronic heating system, however, replaces all of this with a structure that supplies the domestic hot water and satisfies all interior heating needs, making it one of the most popular features in diesel coaches today.Why Hydronic?
Built by Aqua-Hot (previously Oasis) Heating Systems, these systems use a boiler to circulate hot antifreeze through a series of heat exchangers found throughout the motorhome. The advanced technology nearly eliminates the fumes normally associated with propane or diesel use and is quiet, as well. This is good for you, good for your neighbors, and good for the environment.
The system evenly heats your coach's interior with multiple heat zones. As the temperature of a zone drops below your thermostat setting, a heat exchanger begins circulating heat not only from the floor to the ceiling, but also side to side.
Plus, it acts as the hot water heater, as well. In fact, water pumped through the boiler is instantly heated meaning that you won't run out of hot water until you actually run out of water.How the System Works
Propylene glycol antifreeze is heated in the boiler and then circulated through various heat exchangers located within the walls and under the flooring throughout the coach to provide quiet, eco-friendly heat. A boiler the size of a traditional heating unit makes it fairly simple to incorporate it in many new model homes. Unfortunately, due to how the system is structured, Aqua-Hot heating is typically only installed when an RV is originally manufactured.
Enjoying Hydronic Heat
These days, Aqua-Hot comes standard in many luxury coaches and is offered as an up-grade option in several others, as well as fifth wheels. For example, you can find the Aqua-Hot hydronic system available through American Coach, Fleetwood, and Itasca, to name a few.
If you want to have a hydronic heat system installed in your existing motorhome there are a few DIY options. However, if you aren't terribly skilled—and you weren't planning to gut your interior—it's a project that would be better left to a professional. Keep in mind, though, that such a renovation includes the installation of the correct Aqua-Hot heater for your RV's size, as well as insulated PEX tubing embedded in the floor and walls. Then, of course, you would have to replace your walls and flooring!In Conclusion
As you can tell, this isn't a project for the faint of heart. Fortunately, however, there are several options if you are looking for a new or previously-owned RV. This system provides a superior source of warmth and hot water. It provides a quiet, evenly-distributed heat, hot-water on demand, and it's eco-friendly as well.
