Controlled Energy Corp. has introduced the T-K1 to its line of high-efficiency tankless water heaters. The T-K1 delivers nearly 5 gallons of hot water continuously. The tankless design and computerized temperature control ensure that the unit will provide an endless supply of hot water at the desired temperature. The T-K1's electronic ignition means that gas is consumed only when hot water is used, meaning no energy is wasted when the hot water is not in use. It measures 2.2 cubic feet and weighs 60 lbs., and it can be installed in a variety of locations, indoors or out, due to its versatile venting system that allows for vertical venting into a flue, or horizontal venting with a power vent.
