Takagi T-K3 Review:

The Takagi T-K3 water heater is an excellent water heater when it comes to efficiency – it is very efficient there by saving your money and keeping you tension free. The large flow capacity with parallel connections is more than enough to meet the requirements of even large residential complexes and even many commercial projects.

The performance depends on the initial temperature of the ground water – But even for places with cold ground water this is the ideal water heater as it gives a rate of about 4.1 GPM or 246 GPH at 40°F.
