4 Best Types of Food Truck Water Heater

Are you remodeling your food truck and you are wondering what size of hot water heater to use? If YES, here are the 5 best water heaters for food trucks. A functional water system is a critical part of a standard food truck.

In fact, the water system’s built-in holding tank in any truck is expected to be FDA approved before it can pass inspection. Thankfully, water tanks in most food trucks today offer the same quality as those found in a restaurant sink.

Note that having a reliable source of running water is very crucial to the daily running of any food business. For a food truck, all the hot water it requires is expected to be generated right there in the vehicle. Hot water is used during and after cooking to clean and sanitize dirty utensils. The water system in any food truck generates hot water through a water heater.

What is the Right Size of Water Heater to Use?

A food truck’s water heater will be powered by electricity. It simply entails that they are easy to install and efficient in production. Water reservoirs could, however, be a problem if you settle for one that is not big enough to supply the required quantity of water.

If your electricity source is 120V and 20 amps maximum, which is common in RVs, food trucks, boats, and outdoor bars, then any/every tankless water heater will heat your Incoming Water Temperature by about 33°F at a flow rate of 0.5 GPM.

And if the truck’s sink flows faster than 0.5 GPM, then the incoming water temperature increase will be proportionately less than 33°F.

With that said, there are newly developed systems that supply hot water on demand. They are efficient and will continue to deliver hot water as long as your fresh water tank doesn’t run dry. Also, note that some water heaters are designed to run on gas.

Gas-powered systems such as this have their merits as well as their disadvantages. Note that a gas water heater will lighten the electrical load on your generator but will leave you with a pollution problem.

In addition, you will need a vent outside the truck to channel out the dangerous carbon monoxide fumes being generated. Gas water heaters are fast at heating water up but require inspectors to come to check them out occasionally.
