Cut water-heating costs by up to 50 percent with the Bosch AquaStar 125HX-NG tankless water heater. The 125HX-NG is fueled by natural gas and heats water on demand, supplying hot water at a rate of 4.3 gallons per minute--enough to meet the needs of one major application (shower, dishwasher, etc.) at a time. When there is no demand for hot water, the unit�s gas valve automatically closes, and the burners turn off. The 125HX-NG features a unique electronic ignition system that uses the flow of the water as its source for ignition rather than electricity or a standing pilot. Stainless steel burners and a copper heat exchanger help ensure long life, and a modulating gas valve provides temperature control. A boon for basement-finishing plans, the 125HX-NG takes up much less space than a tank heater and can be mounted in a closet or on a wall on included hooks. The unit is designed to vent vertically, but the optional AQ1 kit allows you to vent it horizontally through a wall. The purchase is covered by a manufacturer�s 12-year limited warranty on the heat exchanger and a two-year limited warranty on parts. Check with your gas provider for energy rebates on this purchase.

PowerStar water heaters bring the performance of tankless models to situations where an electric unit is preferred. Compact and powerful, both the AE115 and the AE125 can supply enough hot water to support one major application (shower, dishwasher, etc.) at a time. The AE115 delivers up to 2.6 gallons per minute, while the AE125 delivers up to 4.0 gallons per minute. With both units, an external temperature-control knob and an internal flow sensor help to ensure a constant output temperature. PowerStar heaters are built to last, save valuable floor space, and mount easily on the wall. The AE115 is not recommended in climates where annual groundwater temperature is less that 60 degrees Fahrenheit. If you live in such a locale, consider the AE125 instead. Both models are covered by a manufacturer’s 10-year limited warranty on the solid-copper heat exchanger and a one-year limited warranty on parts. NOTE: The AE115 requires minimum electrical service to the home of 150 amps, and the AE125 requires a minimum of 200 amps.
