Gas or electric commercial water heater. Which is best for my business?

Choosing the right water heater for your business is an important decision. Whether you’re upgrading a commercial water heater or building your business from the ground up, you want the right fit for your needs.

Which One is Best for My Business?

You’ll need to consider a few factors when choosing what’s best for your business. To name a few, you’ll need to know,

  • The amount of energy needed to keep the water hot.
  • How much hot water your business will require to operate
  • What type of space the water heater will fit in
  • And more

Water heater options depend on the needs of the commercial environment and building specifics. For example, restaurants have a different demand for hot water and floor plans than apartment buildings. Let’s start with some basic advantages to gas and electric tank-type water heaters.

Gas or Electric Commercial Water Heater

Heating water is one of the largest expenses for a business. That makes picking the right commercial water heater an important decision. So which is the best for you? Let’s take a look at both.


The most common commercial water heater remains natural gas. Generally, gas water heaters:

  • Heat about twice as fast as electric heaters
  • Lower monthly utility bills
  • Have a high flow rate
  • Aren’t affected by power outages
  • Are more efficient than electric water heaters

Gas water heaters offer many benefits for commercial properties.


Electric water heaters are ideal for small to midsize commercial applications. They offer many benefits such as

  • Lower operating costs
  • No flues
  • Flexible, easy installation
  • Increased efficiency
  • Long-life tank design
  • Minimal heat-loss design

Electric water heating is a simple, convenient way to heat water in commercial buildings. Here are eight more reasons to choose an electric water heater for your business or facility.

Defining Efficiency

Efficiency ratings are measured differently for commercial water heaters and residential units.

Residential water heaters have a gas input of 75,000 BTU or less. The US Department of Energy (DOE) tests and assigns an official Energy Factor rating (EF rating). You will only see Energy Star ratings on residential consumer-grade equipment for this reason.

Commercial water heaters have a gas input higher than 75,000 BTUs, so they aren’t given an EF rating. Instead, their energy efficiency is determined by thermal efficiency. Thermal efficiency refers to how much energy the unit can extract from the fuel used. “High efficiency” commercial-grade units have a 90% or higher thermal efficiency.

Hot water is critical to health, sanitation, and safety. But it’s especially vital to the industries we serve. At Wallingford Sales, you can be sure to get the best prices on top-quality commercial water heater brands, whether you need a gas or electric commercial water heater.
