The T-K3-0S is the company’s first tankless water heater built only for outdoor installations. 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. Since it can only be installed outside, the T-K3-0S is ideal for warmer climates. It features a built-in power venting system and does not require any additional Category III venting or vent caps.
