AHI Technologies Introduces Tankless Water Heater Using ½-inch Gas Supply
AHI Technologies has added AHG-T42 to its gas tankless water heater line. Unlike standard ¾-in. gas supply lines for whole house or light commercial applications on the market, the AHG-T42 is the only model on the market that fits the standard ½-in. natural or propane gas supply line in most homes, significantly decreasing installation costs, company sources say. The AHG-T42 doesn’t take up much space, yet it provides unlimited hot water on demand. The AHG-T42 can be used for supplemental water heating needs such as commercial dish washing.
AHI Technologies’ gas tankless water heaters meet EnergyStar® requirements and are enabled with H2O Saver Technology®. The H2O Saver Technology includes an oxygen-free copper heat exchanger and digital controls that allow users to control hot water consumption and conserve water. With the push of a button, users can set the hot water amount and the unit conveniently warns you with a buzzer that your desired hot water amount has been reached.
