Takagi T-K3 (TK3) - Flash Tankless Gas Water Heater
Takagi T-K3 (wall brackets are built onto the unit)	This tankless gas water heater features: Small water heater, BIG BITE! - The T-K3 (TK3) measures 20.5" x 13.8" x 8.5" which allows for installation in spaces with limited area or in locations closer to the point of use. This results in less travel-time through pipes, which means less energy is wasted. Save Money - No storage tank to clog with deposits and rust. No pilot light to waste gas. Computer-controlled burners use only the gas required according to demand, which significantly increases efficiency. Giant Flexibility - Capable of handling water flows ranging from .5 to 7.0 gallons per minute, with heating capability of 11,000 to 199,000 BTU, the T-K3 has the widest range on the market, all controlled by a computer board and sensors checking for flow, temperature and demand. Save Energy - Water is only heated as it is used, without need for a holding tank to waste energy. Computer controlled electronic ignition allows the T-K3 (TK3) to operate without a pilot light and save up to 50% off utility cost. Peace of Mind - Safety is constantly monitored internally with an advanced system of circuits and sensors checking for over or under-heating, freeze conditions, gas levels, water levels, even air and venting conditions. Added protection - The T-K3 (TK3) comes equipped with heating blocks to prevent freezing which can damage the heat exchanger. The T-K3 also ignites automatically, without the water flow, to prevent freezing the heat exchanger as well. Click here for more information
