Pipe Insert Heaters
A common method used for tank heating. This method would be our top recommendation if it weren’t for three factors. Complexity, cost, and insulation.
You can see by the picture, it’s not easy to set up. These heaters retail higher than their competitors, and they provide zero insulation. As soon as the power cuts out, the temperature is going to immediately drop.
Heating Bands
Another common method for heating. The metal strip placed around the base heats up, and over time heats the whole tank. We don’t recommend this one.
Like the pipe inserts, there is no insulation. No insulation means a constant power flow is necessary to keep contents at optimal temperatures. Not to mention, it can take up to 18 hours for one of these little bands to heat up the tank in the first place.
Powerblankets
We’ve done our research and have decided that Powerblanket is the most cost effective, insulating and efficient option currently on the market. It’s just as simple as it looks.
Wrap your tanks in an electric blanket, turn up the heat and watch it go. The patented heat-spreading technology ensures an even temperature throughout the tank. Since it’s a blanket, it’s sure to keep the tank warm even during a power outage.

When working with compressed gases you will quickly learn that each gas has its sweet spot. In a liquid propane (LP) tank for example, part of the volume is occupied by liquid and part is occupied by gas. The pressure of the gas is governed by the temperature of the liquid. When a propane tank gets too hot during warm summer months, liquid heats, gases expand, often causing release valves to engage. Too cold, and pressure will fall creating the opposite effect… No pressure! So how do you find that sweet spot and keep your propane pressure at MAXIMUM safe output? You can start by wrapping your tanks in something to keep them warm.

Oil Tank Heating Tips

I’m not a scientist, but I do know from experience that it’s important to keep tanks heated to specific temperatures in order to achieve optimal output. Gas & Oil Companies heat their frac tanks and pipe valves to keep viscous fluids flowing. Businesses dealing with compressed gas in cold weather conditions require methods to heat their cylinders. Even home owners require methods for heatng oil & propane tanks and above ground storage drums.
For years, methods for oil & gas tank heating were limited and often dangerous… until now! Powerblanket has developed a series of oil tank heaters and large silo tank wraps that heat, insulate, and protect materials from the effects of harsh winter weather. Availalble in both 120v & 240v models, Powerblanket is the most affordable method for heating and warming large tanks, drums, cylinders, and silos.
Powerblanket’s are so effective at insulating and protecting tanks and drums, that some customers forgo the heated portion of the blanket and simply order the Powerblanket for its effective ability to insulate their tanks and keep heat from escaping.
