Takagi TK3-OS Tankless Outdoor Water Heater (Natural Gas)

**This product qualifies for the Federal Tax Credit. Please see the bottom of this description for tax credit details. The T-K3-OS is one of Takagi's smaller tankless water heaters. At 13.8 inches wide and weighing only 40 pounds, its ultra-compact design allows it to be mounted on a wall or installed between two wall studs using Takagi's TK-RBO2 recess box, so it's even more inconspicuous. Since it can only be installed outside, the T-K3-OS is ideal for warmer climates. The T-K3-OS features a built-in power venting system, but unlike any of its predecessors, the new tankless water heater does not require any additional Category III venting or vent caps, making installation one step easier for its installers. It can provide an unlimited supply of hot water continuously because there is no storage tank to heat and reheat. The T-K3-0S starts heating water at 0.5 gallons per minute (GPM), and can keep that endless supply of hot water running from as low as 0.4 GPM up to a maximum flow rate of 7.0 GPM. Takagi'...
