Also known as heat blankets, these heaters completely surround containers for fast heating and increased heat retention in unheated and drafty areas. Do not use in hazardous areas.

Heaters with an adjustable thermostat automatically turn on when the temperature drops below your set temperature and off when it rises above your set temperature. Adjust the set temperature with the keypad.

Heaters with a nonadjustable thermostat output a consistent heat and turn on and off intermittently to maintain that temperature. Since you can’t change their heat output, there’s no need to monitor them and no risk of tampering, which could damage containers and their contents. Add insulated expansion strips to make heaters for 22 1/2" dia. containers fit drums with a diameter up to 24.2". They’re also needed for these heaters to fit around drums with removable lids.

Add insulated top covers to reduce heat loss and speed up heating.

These ETL-listed heaters keep containers warm in areas where hazardous material is present. Also known as heat blankets, they surround drums and totes to heat them up quickly. They’re also insulated with foam or fiberglass to retain heat. They have a built-in thermostat that cycles on and off to keep contents at a set temperature. There's no need to monitor these heaters—since the temperature can’t be changed, there’s no risk of tampering.

Hazardous location environmental ratings indicate whether manufacturers have included safety features in products to facilitate their safe use in a hazardous environment. Before selecting a product for a hazardous location, ensure it is rated for your environment. See About Hazardous Location Environmental Ratings.

Strap these heaters around cylinders to keep gas flowing when the temperature drops. Also known as heat blankets, they heat cylinders from the outside, safely warming liquefied gas enough so that it can vaporize. They’re also lined with acrylic insulation to retain heat. The thermostat is adjustable, and it automatically turns the heater on or off to keep your cylinder at a consistent temperature. They’re sized to fit industry-standard cylinders.

Made with tough Cordura fabric, these heaters resist mold and mildew, and they’re difficult to tear. Both the fabric and the NEMA 4X-rated controller are weather-resistant, so you can install these heaters on outdoor tanks. Check the current temperature on the LCD display and use the keypad to make changes. Do not use these heaters in hazardous areas.

Keep gas flowing even when the temperature drops—also known as heat blankets, these heaters wrap around propane tanks to safely warm liquefied gas so it can vaporize. They’re insulated with foam, so they retain heat even in chilly environments. Their built-in thermostat heats up to 90° F, then automatically adjusts the power output to keep your tank consistently warm. Because you can’t adjust the thermostat, there’s no risk of accidentally changing the set temperature. These heaters are sized to fit industry-standard propane tanks. Quickly install and remove them using the buckles or latches.

Made of heavy duty vinyl, these heaters stand up to scuffs, water, and UV rays, so they last even outdoors. The vinyl is NFPA rated for flame retardance; however, you shouldn’t use these heaters near combustible gases or dust. A GFCI is built into the power cord to prevent electrical shocks.

Keep your battery running at full power even when the temperature drops—these heaters warm batteries quickly without overheating them. They fit most automotive and marine batteries. Made from oil- and acid-resistant materials, they stand up to the harsh conditions under the hood of your vehicle. Add a timer switch to automatically turn them on and off at a set time and day.

Band heaters are best if you want to move the heater from vehicle to vehicle or only need to heat your battery every now and then. They heat faster and more evenly than sheet heaters, and they’re simpler to install—just wrap them around your installed battery. However, you have to take them off before running your vehicle, so you can’t leave them on permanently.

Sheet heaters are best when you need to heat your battery frequently. They heat from underneath, so you’ll need to remove your battery to install them. Once installed, you can safely leave them inside your vehicle as it runs. Just make sure to secure the cord so it doesn’t get caught on any moving parts.
