The TK2 water heater is a tankless water heater that delivers up to 6.9 gallons of hot water continuously. The computer modulated burners use only the gas required to heat the water required - without wasting any gas. The TKD20 has an electric ignition and uses no energy when not producing hot water.

The TKD20 water heater is capable of handling water flows ranging from 0.75 to 6.9 gallons per minute, with heating capability of 19,000 to 185,000 btu, the Takagi Flash TKD20 water heater has the widest range on the market, all controlled by a computer board and sensors checking for flow, temperature and demand. The Direct Vent TK2D0 uses stainless steel 4-inch vent for the exhaust and a 3-inch vent for the intake air.

Flash TKD20 is far more fuel-efficient that traditional systems, with considerably lower carbon monoxide and NOX (nitrous oxides) emissions. It is quieter, safer and more effective than any other tankless water heater on the market.

Water heaters should do a lot more than take up space, run up utility bills and run cold every time out-of-town guests increase the household's demand for hot water. That's why Takagi, long known as a leader in tankless water heater technology, has unveiled a new generation of tankless water heaters with the Flash T-KD20.

Designed for high-efficiency residential use, the T-KD20 is an incredibly small system - measuring 2.2 cubic feet and 60 pounds - that provides enormous benefits. Unlike traditional water heaters that operate continuously to keep the water in the tank at a constant temperature, Takagi's T-KD20 delivers more than 250 gallons of hot water per hour on demand, yielding an endless supply of hot water, as well as reduced energy consumption. Additionally, the T-KD20's direct-vent system to the outside makes it ideal for climate-controlled environments.

Consumers aren't the the only ones who should take note of Takagi's many advantages. Homebuilders can reap major compliance rewards, while helping their buyers reduce water heating costs by anywhere from 25 to 60 percent, depending upon individual usage.

According to John Eash, an architect and energy specialist with the California Energy Commission's Residential Buildings & Appliances Office, " If builders find out about the tremendous compliance credit given for the Takagi, they won't be able to make these tankless water heaters fast enough."

The temperature dip switch outputs are 105, 120 or 180 degrees. If you need a different temperature, you will need the remote (TK-RE01).
