The Complete Guide to RV Hydronic Heating Systems, Boiler Antifreeze, and Refractometer Maintenance

Protect Your Aqua-Hot®, Alde®, Oasis®, Webasto®, or PrecisionTemp Investment with Proper Glycol Testing

Luxury RVs are designed to provide the comforts of home wherever the road leads. Unlimited hot showers, warm floors on a freezing morning, quiet interior heat, and reliable hot water in sub-zero temperatures are all possible because of one remarkable piece of equipment: the hydronic heating system.

Unlike traditional RV furnaces that simply blow hot air through ducts, hydronic systems circulate heated boiler antifreeze through a network of heat exchangers to provide comfortable interior heating while simultaneously producing continuous domestic hot water. Many premium systems can also preheat the engine, warm storage compartments, protect plumbing from freezing, and even supply radiant floor heating.

These sophisticated systems are commonly found in luxury motorhomes, premium fifth wheels, expedition vehicles, and custom RV conversions. Manufacturers such as Aqua-Hot®, Alde®, Oasis (ITR)®, Webasto®, and PrecisionTemp® have earned reputations for delivering exceptional comfort in virtually any climate.

However, this level of comfort comes with an important responsibility: routine maintenance.
