Heat pump water heaters gain market
That big old electric water heater in your dad’s utility closet may be on its way to becoming an antique before too long. Indeed, the last decade has ushered in many innovations in water heater technology—from smaller units with on-demand supply and digitized thermometer controls to tankless heaters. And as the market certainly shows interest in combining a higher level of convenience with energy-efficient technology, an impressive variety of water heater innovations has hit the shelves in the United States. Among them is the air-source heat pump water heater, which works by pulling heat from the air, compressing it and then releasing it into a water tank. By simply moving heat, instead of generating it directly from scratch, the technology is remarkably energy-efficient.
“The Accelera 300 has been saving people money on their energy bills in Europe for over 25 years,” says Bill Riley, a sales and marketing specialist for Stiebel Eltron. The German water heater manufacturer recently introduced the heat pump water heater to North America, where homeowners can reduce hot water bills by up to 80 percent, says Riley. “The beauty of heat pump water heating technology is that the amount of electrical energy needed to create hot water is greatly reduced compared to a conventional electric tank-type water heater,” Riley says. “The Accelera 300 can extract up to 80 percent of its energy requirements from the energy in the air around it.”
