As you can see the T-K3 incorporates all those "why-don''t-you-have-this?" features into this one new product. Its larger flow capacity through parallel connections will meet the hot-water needs of most high-volume residential applications and many commercial projects too. In short the T-K3 fills the gap between the single residential heater and multiple commercial T-M1 units. Performance depends on the temperature of the ground water of course: At a delta T of 60 degrees F in warmer areas - for example where the winter ground water is 60 degrees F and with the output set at 122 degrees F - the T-K3 will provide a 5.4 GPM or 324 GPH. In colder areas where the input temperature may be 40 degrees F or less expect a flow rate about 4.1 GPM or 246 GPH.
