Much lighter (45 lbs) and more benefit!
At just two-and-a half feet high, Flash T-K1S generates hot water as needed using just 2.2 cubic feet of space. Weighing in at only 45 pounds and with a first-hour flow rate of over 240 gallons, this compact model produces endless hot water long after conventional units have run cold. Wall-mounted inside or outside, the T-K1S provides 190,000 BTUs of continuous heat, while offering thermal efficiency of 85% using natural gas and 87% with propane.
WITHOUT the remote controller, Temperature can be adjusted as low as 113F, up to 182F, which makes it perfect for floor heating applications.
