Rheem Debuts First-of-its-Kind Residential Tank Water Heater
Rheem’s new model is the industry’s first water heater to use condensing technology in a residential, tank design; unit achieves a 0.80 EF and costs only $19 per month to operate
ATLANTA, February 4, 2013—Today, Rheem unveiled the new High-Efficiency Condensing Power Direct Vent (PDV) Water Heater. This ENERGY STAR®-qualified water heater is the first in the industry to employ high-efficiency condensing technology in a residential tank design.
The Rheem High-Efficiency Condensing PDV unit achieves a 0.80 Energy Factor (EF), which is the highest EF available today for residential tank-type water heaters. Most typical gas-fired storage water heaters have a 0.59 EF and even ones that are Residential ENERGY STAR (Version 2.0) -qualified are only required to have a 0.67 EF (source: U.S. Environmental Protection Agency).
“This new Rheem unit is 26 percent more efficient than most typical gas water heaters, and it only costs about $19 per month to operate,” said Brad Johnson, product manager, Rheem Water Heating Division. “Since natural gas prices are at an all-time low, contractors can have a hard time convincing homeowners to choose a high-efficiency unit, and that’s just because it’ll take longer for them to make up the incremental price difference when they’re paying rock-bottom gas rates each month. With this unit, however, homeowners can see utility savings immediately, so they can actually hit a faster payback point on the investment.”
Rheem’s existing water heating platform leverages high-efficiency condensing technology in the company’s Prestige™ Series line of tankless gas water heaters, and in certain commercial products like the Rheem SPIDERfire® line of commercial water heaters. In the High Efficiency Condensing PDV model, the main flue is capped at the top of the unit. It forces gases down through a proprietary five-coil submerged heat exchanger, which loops around the center flue. The process keeps flue gas in contact with water for a longer period of time, meaning that more heat is transferred to the water.
Because the High-Efficiency Condensing PDV Water Heater delivers more heat to the water, less heat exhausts from the vent. The cooler flue gases permit venting through low-cost 2- or 3-inch PVC piping. The use of PVC simplifies the installation process for the contractor and saves the homeowner costs in venting, components and installation.
In addition, this unit comes with a factory-installed exhaust riser, which conveniently vents at the top of the unit, so contractors don’t have to spend time constructing a bulky side riser. Should a service issue arise, Rheem has included an integrated diagnostic system that helps contractors quickly assess any problems and facilitate faster service calls.
The High-Efficiency Condensing PDV Water Heater is available in the U.S. in 48- and 38-gallon capacities. It will soon launch in Canada in these same capacities, and the unit will also be ENERGY STAR-qualified in Canada. The 48-gallon model has a first hour rating (FHR) of 93 gallons, and the 38-gallon model has a FHR of 74 gallons. The recovery rate varies based upon the model chosen, but it can recover between 43.6 and 48.5 gallons of hot water at a 90 degree Fahrenheit rise in temperature. Finally, the unit includes a six-year limited warranty for the tank and its parts.
