A reliable and efficient hot water system is crucial for smooth operations in many industrial settings. An on-demand tankless water heater is a popular choice for providing hot water as needed without the need for storage tanks. Unlike traditional hot water systems, on-demand tankless water heaters heat the water as it flows through the unit, reducing energy consumption and costs. However, before you purchase an on-demand tankless water heater, there are several factors that you need to consider.

Here are the key steps in selecting an on-demand tankless water heater:

1. Determine Your Hot Water Needs

If your application requires filling a large tank with hot water and then using it for process use later, an on-demand tankless water heater is ideal. This is common in the pharmaceutical and cosmetic industries, where hot water is needed in cycles. Instead of storing hot water in a large tank, an on-demand tankless water heater can supply heated water as it’s being used.

2. Choose the Right Size

The size of the on-demand heater will determine how long it takes to fill up a storage tank. If the demand heater is supplying hot water immediately as it is being used, the use rate will determine the heater size.

3. Calculate the Temperature Rise

To calculate the temperature rise, subtract the incoming cold water temperature from the needed outlet temperature. The on-demand tankless water heater will turn on and off to maintain the temperature. Ensure you choose a unit with sufficient heating power to achieve your desired temperature rise.

4. Select the Energy Source

On-demand tankless water heaters can use various fuels, including natural gas, propane, oil, or electricity. Electrical heating is more expensive than power, but fuels require venting exhaust fumes into the atmosphere. Consider the cost, availability, and environmental impact of each fuel option.

5. Get a Custom Quote

An on-demand tankless water heater for industrial use should be properly sized and equipped for specific applications. The Spartan Engineering department can provide a custom quote that considers all the factors discussed above. This ensures optimal efficiency, reliability, and longevity. NOTE: Spartan Mfg. Corp. does not manufacture water heaters for residential applications.
