Commercial Services


  • Why does “just give me the same water heater I have again” not work with today’s equipment?

    Twenty years ago the trend in commercial water heaters was to oversize the equipment to ensure water would never be an issue. Since then technology has changed and today’s higher efficiency water heaters will be damaged if you do that. When a commercial water heater is oversized, it causes it to short cycle. That means, it does not draw down its full capacity and heats a small portion of water more frequently. With today’s higher efficiency heat exchangers, this makes them work much harder than they should and burn themselves out quicker. Boilers are even more sensitive to this issue. For commercial water heaters today, proper sizing to fit the peak loads will maximize the product life and energy efficiency of the unit. That is why we take the time to do a proper load calculation and fit the right size to your operation. Boilers require a heat loss calculation as well, for proper sizing.

    You don’t want to just replace like for like without taking a fresh look. And it may save you substantial dollars as well. One recent customer we serviced was a small restaurant that was taking over a space formerly occupied by a commercial laundry. The laundry had much higher water utilization than the restaurant will ever have. They needed new water heaters but because we re-sized them to their usage, they were able to save $11,000 vs just replacing the bigger units that were in there.

  • Do you provide restaurant plumbing services?

    Yes, we cater to restaurants. We have many Seattle restaurant plumbing customers and can provide plumbing services to fit your needs, from plumbing maintenance agreements, to water heater inspection and water heater replacement to drain cleaning and repiping. We know the plumbing demands of restaurants are high. You likely have heavy drain cleaning needs and not every plumbing company can reliably meet them. Any change in restaurant plumbing can be expensive. With Washington Energy you get our 55 years of experience and expert advice. We will install the right system for your restaurant operation and provide follow up support, inspections and maintenance once we install it. Plus, we’ll have your back 24/7 with emergency plumbing services 365 days a year.

  • What costs only $500 and can save your business?

    A water leak protection system. This goes beyond leak detection to actually shut off water when water sensors detect a leak. Made by QMI, this product can handle your main water shut off, or upgrade for multiple appliances, gas line shut off and email notification. For home and business use. The water leak protection system is installed by our licensed plumbers.

  • What are the top models of replacement commercial water heaters that you carry?
