Takagi T-K3-OS Tankless Water Heater Outdoor Model (Natural Gas), 190KBTU

The Takagi T-K3-OS-NG Takagi Tankless Water Heater is a Natural Gas model and is built for outdoor installations only. This model is ideal for warmer climates, does not require any additional venting (which makes the set-up process much easier and reduces the installation costs) and comes with a built-in freeze protection. It is perfect for domestic hot water or hydronic/radiant heating applications in small to mid size residential homes or apartments with 2-3 bathrooms and can replace a 50-gallon standard storage tank-type water heater.

When compared to a regular storage-tank water heater, installing the T-K3-OS model can save homeowners up to 45% on their monthly gas bills.

The Takagi T-K3-OS-NG model does not require any special venting parts and comes with mounting brackets, a free set of service isolator valves and a pressure relief valve.
