Natural Gas Tankless Water Heater, Indoor 4.0 GPM, 90,000 BTU Instant Hot Water Heater, InstaGas Classic 90

About this item

【Smaller size and better performance】It is only 1/4 the size of a 50 gallon tank water heater, yet it produces approximately 4.0 GPM of hot water through 90,000 BTU for both bathroom and kitchen hot water demand. The highly integrated components also provide greater safety from water pressure surges without the need to install an expansion tank.
【Fast and endless supply of hot water】The heat exchanger quickly heats the water to a maximum of 149℉ in a short time, and the hot water is quickly piped through to the shower and tap. No need to wait for the water temperature to heat up slowly like a tank water heater. After that it continues to operate at approximately 4.0 GPM for 40 minutes, which is enough time to produce almost 160 gallons of hot water.
【Stable and comfortable temperature】Benefiting from the calculation and control of the heating power 1000/s by the chip, the temperature difference of the water can be precisely controlled within ±2°F.
【High compatibility and easy installation】Most tank water heaters have exhaust vent, water and gas pipe that can be universally used in tankless, requiring only a simple re-layout. If installing a tankless water heater in a new house, its compact size makes it easy to install. Of course, we recommend that all installations are carried out in accordance with local building and plumbing codes by licensed professionals.
【Excellent quality and service】CSA certification in the USA and Canada. Superior safety and durability using the world's most advanced technology. FOGATTI provide 5 years warranty on heat exchanger and 2 years warranty on other parts.
【Note】1. Not recommended in excess of 2000 feet above sea level. 2. This tankless gas water heater must be installed in a well-ventilated area. 3. Requires additional purchase of 3-inch diameter exhaust pipe.
