Takagi Light Commercial Tankless Water Heater T-K4-IN-NG
Released in 2010, the T-K4 improves upon many of the features from the T-K3.
The T-K4 is one of Takagi’s smaller tankless water heaters. At 13.8 inches wide and weighing only 38 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 (for OS model), so it's even more inconspicuous.
The T-K4-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-K4 starts heating water as soon as flow is detected, and can keep that endless supply of hot water running from as low as 0.4 GPM up to a maximum flow rate of 8.0 GPM.
Takagi's newest tankless water heater also features an energy factor of 0.82, so it is extremely efficient and environmentally friendly. Since tankless water heaters only burn gas when hot water is needed, installing this unit can help homeowners save up to 45% on their monthly gas bills.
The T-K4 also offers four separate temperature settings, ranging from 113° to 140°. To achieve any temperatures other than those presets, your client will require the TK-RE02 temperature controller
