' "(E) For pool heaters, thermal efficiency. "(23) The term 'furnace' means a product which utilizes only single-phase electric current, or single-phase electric current or DC current in conjunction with natural gas, propane, or home heating oil, and which— "(A) is designed to be the principal heating source for the living space of a residence; "(B) is not contained within the same cabinet with a central air conditioner whose rated cooling capacity is above 65,000 Btu per hour; "(C) is an electric central furnace, electric boiler, forced^. air central furnace, gravity central furnace, or low pressure r steam or hot water boiler; and "(D) has a heat input rate of less than 300,000 Btu per hour for electric boilers and low pressure steam or hot water boilers and less than 225,000 Btu per hour for forcedair central furnaces, gravity central furnaces, and electric central furnaces. "(24) The terms 'heat pump' or 'reverse cycle' mean a product, other than a packaged terminal heat pump, which— "(A) consists of one or more assemblies; "(B) is powered by single phase electric current; "(C) is rated below 65,000 Btu per hour; iv "(D) utilizes an indoor conditioning coil, compressors, and refrigerant-to-outdoor-air heat exchanger to provide air B'^ heating; and "(E) may also provide air cooling, dehumidifying, humidifying circulating, and air cleaning. "(25) The term 'pool heater' means an appliance designed for heating nonpotable water contained at atmospheric pressure, including heating water in swimming pools, spas, hot tubs and similar applications. "(26) The term 'thermal efficiency of pool heaters' means a measure of the heat in the water delivered at the heater outlet divided by the heat input of the pool heater as measured under test conditions specified in section 2.8.1 of the American National Standard for Gas Fired Pool Heaters, Z21.56-1986, or as may be prescribed by the Secretary. "(27) "The term 'water heater' means a product which utilizes oil, gas, or electricity to heat potable water for use outside the heater upon demand, including— "(A) storage type units which heat and store water at a thermostatically controlled temperature, including gas storage water heaters with an input of 75,000 Btu per hour or less, oil storage water heaters with an input of 105,000 Btu
