Takagi T-K3 Tankless Water Heater T-K3 Water Heater
Takagi's smallest, most versatile and most powerful residential model. Connect up to four Takagi gas tankless water heaters together to meet the demands of even the largest homes! The compact T-K3 measures under 14 inches wide, so it will fit snuggly between two wall studs to save space. But the T-K3 is also powerful. With Takagi's new easy link technology, the T-K3 will meet the hot-water needs of most high volume residential applications.


The Takagi Gas Tankless Water Heater can be installed inside our outside in warmer climates (with optional outdoor vent kit). The Takagi TK3 can also be used for hydronic heating systems such as Radiant Underfloor heating and Hydronic Baseboard Heating. Your choice!

If you have any questions about how to use this as a gas heat source - please click on the "contact us" on the top of this page.
