Rollie Oil Tank Heaters

Rollie Technical Systems provides quality tank heaters for residential and commercial applications. Prevents gelling by warming the oil and promoting natural convection in the tank. We offer two types of tank heaters: Model TH tank heater for tanks that draw oil from the bottom or side of the tank, or Model DTH tank heater to draw heated oil from the top of the tank.

  • Prevents the oil from gelling. Heating oil can gel at temperatures as high as 10 degrees. The heater comes on automatically when the outside air temperature falls below 50 F.

  • Installs in Minutes. The heater is installed in any available tank top opening. A pipe wrench is all that's needed.

  • Rugged Construction. All wetted parts are made from super corrosion resistant 6063 aluminum alloy.

  • Automatic Shut Off. To prevent overheating the heater will turn off whenever the oil level in the tank falls below the end of the heater tube.

Two Models to Choose From:

Model TH Heater

For tanks that draw oil from the bottom or side of the tank

Model TH tank heaters are designed to prevent fuel oils from gelling in outdoor storage tanks.   These heaters are inserted through any available tank top opening that can accommodate or be reduced to 1/2 NPT thread.  This model is used primarily in tanks that draw oil from the bottom or side of the tank rather than from the tank top.   The heater is installed as close as possible to the oil outlet.

Model DTH Heater

To draw heated oil from the top of the tank

heater and draw tube
Model DTH tank heaters are also designed to prevent fuel oils from gelling in outdoor storage tanks.   Unlike TH heaters, these heaters consist of an outer draw tube, the tube that extends down into the tank to draw oil out by pumping from the top. This model heats the oil in the draw tube so the first oil out is the warmest. When the oil isn't being pumped it acts as a standard tank heater.

How It Works

Heat is applied to the oil through the heater tube and warms the oil closest to the heater.   As the oil absorbs heat it begins to rise in the tank.   As the warm oil rises, colder oil moves in to take it's place and the cycle continues.  As long as heat is applied to the oil it will continue to rise and fall in the tank.  There is not a significant rise in overall temperature within the tank, it is the oil movement that helps prevent the oil from gelling.
