If you're thinking about buying a truck-mounted tank heater in the near future--whether it be for use in concrete work or any other purpose--you'll want to make sure you're well versed in the tank heater's operation in order to use it safely. Otherwise, you could be putting yourself and others at risk. Read on to explore a few of the most commonly asked questions among new truck-mounted tank heater users.

How to Truck-Mounted Tank Heaters Work?

Understanding the basic operation of your tank heater can help you answer many other related questions about the heater itself. All makes and models can vary slightly in their operation, but all truck-mounted tank heaters operate in a similar way. Specifically, they usually consist of a two heating elements: one that's insulated and one that's not. The purpose of having two separate tanks is that the smaller, insulated tank can be used as a heat source, even when the truck is parked. The tanks themselves are powered by voltage, which is drawn from the truck's battery.

When is it Safe to Turn the Tank Heater On?

This is a great question, as turning the truck-mounted tank heater on when it's not appropriate can lead to damage of the liquids being held in the tanks. Generally, it's safe to turn on a tank heater when there is liquid in the tanks and when the outdoor temperatures approach freezing (0 degrees Celsius or 32 degrees Fahrenheit). It's important, however, to ensure that the outdoor temperatures are expected to remain freezing for an extended period of time.

If the tank heater is left on when temperatures are well above freezing, damage to the tank itself could occur. The same goes for leaving the heater on when there's nothing in the tank.

Can Tanks Be Insulated After a Heater is Installed?

Generally, yes. Once a truck-mounted tank heater system is installed, the addition of insulation can help maintain steady tank temperatures and increase efficiency. Most tank panels are designed to be withstand heat, but it's a good idea to check with the manufacturer before installing insulation-- just to be sure.

These are just a few of the most frequently asked questions about truck-mounted tank heaters. By knowing the answers to these questions, you'll be in a better position to more safely and efficiently operate your new tank heater--whether you're using it in a concrete roller, tank, barrel, or anything in between.
