If the Takagi tankless water heaters do not have a holding tank, how can I get hot water from it?
A. Our tankless water heaters do not hold any hot water. By turning on the faucet, the cold water flow through the flow sensor will turn on the burner. The minimum flow rate to do this is 0.75 gpm, with a flow rate of 0.6 pgm required to maintain the burners. The cold water will be heated up to 176 F.
