Pilot project in restaurant delivers on promise of energy savings

Hybrid water heater proves its value as energy efficient upgrade, provides one-third gain in energy efficiency

FastLogo color [Converted]An energy-efficient hot water system proved its value in a commercial restaurant application during a special project overseen by the Food Service Technology Center and Fast Water Heater Company. The two companies worked together to design a tankless natural gas-powered water heating system for use in the high-demand environment of a fast service restaurant.

Fast Water Heater Company and the Food Service Technology Center worked together to implement and monitor the pilot program at Mexxi’s Taqueria in San Ramon. Food Service Technology Center works to develop and test energy efficiency opportunities for the foodservice industry. The goal of the pilot program was to prove that restaurants can safely migrate to more energy-efficient water heating technologies without sacrificing convenience or food safety.

“We’ve made huge strides in residential hot water energy efficiency in recent years. We felt confident we could prove that those gains translate directly to commercial operations as well,” said Jason Hanleybrown of Fast Water Heater Company. “Restaurants can’t survive without sufficient hot water and this project proved it’s possible to have plenty of hot water on demand using less energy than required by a traditional water heating system.”

Mexxi Taqueria’s traditional 75-gallon hot water heater was removed and a hybrid hot water heater with a wall-mounted reserve tank was installed. With the old system Mexxi’s Taqueria got its hot water with 66.1 percent energy efficiency, the hybrid hot water system netted 88.1 percent energy efficiency.

“The reduction in energy costs will be significant for us over time. It’s also a huge bonus that the hybrid system installed by Fast Water Heater Company takes up so much less space in our kitchen,” said Enrique Gomez, owner of Mexxi’s Taqueria.

The project delivered on all of its goals, with a projected savings in energy costs of more than $300 a year for Mexxi Taqueria. From the perspective of the restaurant owner, however, the opportunity to recapture 8 square feet in his kitchen was perhaps even more valuable. At his current lease rate of $3/square foot, Mr. Gomez can add another $288/year in implied real estate value to the benefit of the conversion, leaving him with a 27% return on investment (assuming a useful life for the equipment of 10 years). Taking all of these factors into account, the investment in an efficient hybrid tankless hot water system will pay for itself in just three and a half years.

Hybrid hot water heater manufacturer Eternal donated the equipment for the project and Fast Water Heater Company handled the installation and helped with the monitoring.

“State and federal regulators are pushing for increased efficiencies in the commercial sector, so we can’t afford to wait on these type of efforts,” added Hanleybrown. “We see tremendous potential for helping California reach its ambitious emissions-reduction goals through partnering with restaurants to adopt energy-saving technologies.”
