Ultra RV Holding Tank Heater

The Ultra RV Holding Tank Heater line is a family of peel-and-stick heat pads. They help keep RV black, gray and fresh water holding tanks from freezing in cold weather. UltraHeat products are made by UHI Worldwide, Inc. in the USA, and the brand has been an RV-industry standard for tank freeze protection since the early 1990s.

Key Features:

• Thermostatic control: a built-in sensor cycles the heater automatically. It turns on when the tank contents cool to about 44°F and turns off once they warm to about 64°F.
• Peel-and-stick installation: a proprietary adhesive backing bonds the pad to a clean tank surface, so installation is simple.
• Low-profile heat panel: the pad mounts directly to the tank underbelly and works with standard RV holding tanks.
• Power options: the line includes models for 120V AC shore power and for 12V DC battery power.
• Plug-in operation: models come with a power cord and molded plug. It can be plugged into a GFCI-protected outlet or, with an accessory switch kit sold separately, hardwired.
• Durable construction: the pads are built for long service life and backed by the manufacturer's warranty.

Choose the model that matches your tank capacity and your preferred power source. These heaters are a practical way to protect your RV plumbing and extend your camping season in cold climates.
