Cape Cod resort saves $1,400/month with Eternal Hybrid Water Heaters

The Cove at Yarmouth was throwing money down the drain with its former hot water heaters. Within an eight to ten year period, the resort was replacing the old tanks at a rate of one to two water heaters per year. Eventually, the resort’s general manager, Michael Edwards, decided it was time to make a change. When he contacted Murphy's Air Conditioning, Heating and Plumbing in Cape Cod, the plumbing manager recommended the Eternal hybrid water heater because of its dependability and energy efficiency. “Ease of installation combined with the energy savings passed on to our customers makes Eternal our preferred water heater. We have several more projects in the works, and we take pride in the brand we are installing,” stated Plumbing Manager Bill Heath.

The Cove at Yarmouth is a 13-acre resort and opened in 1986. Its 229 suites and townhouses create a high demand for hot water. Each accommodation features two full baths and a kitchen area. The resort’s restaurant, athletic facility with guest bathrooms, laundry rooms, and other common area restrooms all use hot water as well. The buildings on the property occupy 212,000 square feet of space.














Before the Eternal installation, the Cove at Yarmouth had 23 standard 100 gallon, 199,000 BTU hot water tanks. The motivating factor for Edwards to replace the old units was the need for a hot water solution that was more energy efficient. “The most significant thing is the energy savings. The Eternals equate to a 12% reduction in my energy bill,” said Edwards who added that he is saving $1,400 a month.

The Eternal installation included 21 GU195S water heaters and five storage tanks. One of the storage tanks is 80 gallons, and the other four are 120 gallon storage tanks. Designed for residential and commercial applications, the GU195S is Eternal’s most powerful unit. It provides endless hot water, but unlike a tankless, it has a small reserve tank inside to maintain water pressure and avoid temperature fluctuation. With the GU195S, installers can use a single unit or multiple units with additional storage to accommodate large applications that have an unpredictable high demand for hot water.

“It was a seamless installation that went smoothly,” said Service Manager Richard Toma of Murphy's Air Conditioning, Heating and Plumbing. To learn more about the product and the company, Toma attended an Eternal hybrid water heater training class. “I felt Eternal offered amazing tech support. From the reliability of the product to the support you get, it’s just great. The best I’ve seen with manufacturers,” he said.

Eternal offers 98% efficiency, is lead free, has close to zero carbon emissions, and exceeds Energy Star standards. Other green initiatives at the resort include the recycling of paper, plastic, and aluminum as well as the use of environmentally friendly cleaning products. The Cove at Yarmouth is located in West Yarmouth, Massachusetts.

For more than 30 years Grand Hall, the maker of Eternal hybrid water heaters, has been acknowledged as an innovative manufacturer of gas appliances and components. The U.S. office is in Dallas, Texas where it has been located since 1985. For more information on Eternal hybrid water heaters, go to
