    Takagi has been delivering innovative residential and commercial hot water solutions for over 60 years. Their line of tankless water heaters are unmatched in quality and diversity, providing the perfect hot water solution for any situation. The TK-310U-E-N features a copper heat exchanger, which helps to stabilize outgoing water temperature and reduce pressure drops compared to a standard stainless steel exchanger. The TK-310U-E-N is also designed to meet Ultra-Low NOx standards, meaning it's good for you wallet and the environment.
  • Ultra-Low NOx Emissions
  • The TK-310U-E-N is designed to qualify for the most stringent Low NOx standards. This includes SCAQMD standards and other air quality management districts meant to limit pollution in the southwest United States.
  • Heavy Duty Heat Exchanger
  • The heat exchanger is built out of commercial-grade copper, providing much better heat transfer than standard stainless steel and designed to be more resilient towards corrosion. Takagi water heaters are built to last and save you money in the process.
  • Multiple Safety Features
  • These models come with a long list of safety features standard. These include: built in freeze protection, manual reset hi limit, an overheat cutoff fuse, inlet and outlet thermistors to monitor temperatures, and a built-in flame sensor.
  • Operating Options
  • Outdoor models come standard with a remote control. The TK-310U-E-N can also be field converted to operate on liquid propane with its included conversion kit.

Fuel Type ? To create heat, some form of fuel is required. Fuel Type specifies what the product uses as an input to create heat.
Natural Gas
Combustion Type
Non-Condensing
Vent Type ? Products that use combustion (burning) of fuel to create heat also create potentially dangerous gasses that need to be exhausted (AKA "Vented"). Depending on the product, venting can be done via a chimney, through a side wall, or use a second vent to provide fresh air to the appliance.
