How to Choose the Right RV Heater

Not all RV heaters are built the same. Whether you need to warm a compact camper van or a full-size motorhome, it's important to choose a heating solution that fits your vehicle type and usage. Dometic offers a range of RV furnaces and water heaters designed for efficient, space-saving installation. Our systems are compatible with a variety of RV models and built for reliable performance throughout the seasons.

Controlling the RV Heater

Operating your RV heater should be simple and stress-free. Most Dometic heating systems come with intuitive controls, but if you're unsure how to turn on your RV heater or adjust the temperature, it's a good idea to consult your user manual. You may find a copy of the manual on the relevant product page. We design our products for ease of use, so you can focus on enjoying your time on the road rather than troubleshooting heat settings.

Maintaining and Draining Your RV Water Heater

Regular maintenance is key to extending the life of your RV water heater. Tasks like draining, flushing, and sanitizing help prevent buildup and keep water running clean and hot. If you're wondering how to drain an RV water heater or how to clean it properly, our customer support articles and how-to guides walk you through the process step by step. Keeping your system in top condition ensures safe, efficient performance all year round.

Hot Water and Comfort, Wherever You Travel

An RV heater isn’t just about warmth—it’s about comfort on the go. With Dometic’s water heaters and space heaters, you can enjoy hot showers and a cozy interior no matter the outside temperature. Whether you're boondocking in the mountains or parking up at a winter campsite, our heating solutions help make your RV feel like home. Need upgrades or extras?
