Takagi TH3SDV Reviews

Rated 5 out of 5 by from Functions as expected. This unit replaced an existing 13 year old 40 gallon tank propane heater that was set up in series after a solar 80 gallon tank. Tankless is a better solution as a backup- boaster heater for solar water heating. When nature provides, the heated water just passes through the Tankless and when nature doesn't the Tankless will take over. Installation was more involved than anticipated, which seems to be the norm with any renovation. Gas lines had to be upgraded to a larger size due to greater demand. Replaced existing copper lines with black iron. I had secured a Little Giant condensate pump to deal with the condensate since the location of the Tankless was in a basement and no drain was accessible by gravity. Pump is not hook up and I'm watching the amount of condensate being generated and have a pail on the floor to catch the condensate. As to date not enough condensate is being generate to install the pump, but will continue to monitor. The outlet end of my condensate drain is a bit below the rim of the pail so if by some unlikely event if the condensate rises to the outlet the unit will shut down. I'm very happy with this Tankless and hope the unit continues to perform with the test of time.
