Energy Efficiency in Restaurants – Water

Tip 5: Water

Water is a huge issue for most restaurants.

Hot water heating can be a major energy cost – even without supplemental heating systems. And, in some locations, the cost of water itself can be extremely steep.

Keeping the temperature setting on the water heater in the 120-130 degree range provides hot enough water at lower costs than higher settings.

Low-flow pre-rinse spray valves (1.6 gallons per minute or less – and required on all spray valves since 2005) are an inexpensive way to cut down on hot water usage.

Always use the auto mode on conveyor-style dishwashers, since in that way the conveyor motor only runs when needed. And, pay attention to the pressure gauge on your dishwasher; readings over 25 psi suggests you are likely using more water than you need to.
