Heat Exchanger Material
Copper/Stainless
Fuel Type
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
Combustion Type
Condensing appliances use leftover thermal energy from combustion gases to heat water in a secondary heat exchanger, resulting in higher efficiency and lower exhaust temperature.
Condensing
Vent Type
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.

Had it installed for 3 weeks. Client is extremely satisfied.
By Brian A.
Mountain Home, Arkansas

Review Posted 03/21/2020
Installation was easy. I replaced a standing 50 gallon gas water heater with this tankless gas unit. Other than having to install a electrical receptacle, extend the gas and both water lines and make sure it was vented properly nothing was a surprise. Follow the manual and it could be a DYI project.

This unit works great, seems to be quality and is priced right
By Dean M.

Review Posted 01/19/2020
This was an easy choice when replacing our 15+ year old direct vent tank unit. Same price or cheaper. Takes up less space and easy to install. Screw it to a wall and make your water and gas connections. The hardest part is running at 3" PVC line out a sidewall.

Review Posted 01/16/2020
I purchased a Takagi tankless water heater 4 years ago and just purchased a second one for our lake home! Absolutely the best value for the money you can buy! Stop thinking about making the switch and do it! Unlimited supply of hot water when you need it. I will only buy a Takagi tankless water heater from now on!
