1. Understanding Food Truck Water Heater Options: Tankless vs. Mini-Tank Water Heaters

Tankless Water Heaters: Tankless systems, also known as on-demand water heaters, provide hot water only as it is needed. They don’t store hot water, which saves on energy costs that would otherwise be spent keeping a tank full of water hot. For food trucks, tankless water heaters are advantageous because they occupy less space and can supply a continuous flow of hot water, which is ideal during peak business hours.

Mini-Tank Water Heaters: Mini-tank water heaters come with a small storage tank that keeps hot water ready for use. These are perfect for food trucks that have moderate hot water needs and limited space. Mini-tanks can be easily installed under sinks or in a cabinet, making them accessible and unobtrusive. They typically range in size from 1 to 6 gallons, providing enough hot water for hand washing and basic cooking needs without the wait time associated with tankless systems.

2. Why Consider Portable Water Heaters?

Portable water heaters designed for camping and outdoor activities can also be a smart choice for food trucks. These units are built to be compact and efficient, often running on propane, which can be ideal for food trucks that already use propane for cooking. Their portability means they can be removed for off-season storage or for maintenance without major hassle.

3. Installation Considerations

Placement: Both tankless and mini-tank water heaters can be installed in various locations within your food truck or trailer. Common installation spots include:

  • Under the Sink: This is a typical location for mini-tank water heaters, as they are compact and can easily fit within the cabinet space.
  • Closet or Cabinet: Tankless water heaters are often installed in a closet or cabinet to keep them out of sight while maximizing space usage.

Power Source: Ensure that your choice of water heater is compatible with your truck’s power setup. Tankless heaters often require substantial electric power or gas, so it’s important to consider your current energy capabilities and whether any upgrades are needed.

4. Selecting the Right System

When selecting a hot water heater for your food truck, consider the following factors:

  • Capacity: Assess the volume of hot water your operation will require during peak hours.
  • Energy Efficiency: Look for models that offer good energy efficiency to reduce operating costs.
  • Recovery Rate: If using a mini-tank, check the recovery rate, which is how quickly the water heats up to the desired temperature.
  • Size and Weight: Consider the physical space and weight capacity of your food truck or trailer.
  • Durability: Opt for units designed to withstand the rigors of mobile food service and varying weather conditions.

5. Compliance and Safety

Lastly, ensure that your hot water system complies with local health and safety regulations. Proper installation by a qualified professional is crucial to prevent any issues related to gas, electric, and water connections, which can pose safety risks.


Selecting the appropriate hot water heating system is crucial for the efficiency and success of your food truck or trailer. Whether you choose a tankless, mini-tank, or a portable system designed for outdoor use, make sure it fits your specific needs and installation constraints. With the right system in place, you can focus more on serving delicious food and less on operational challenges.
