What it delivers
The Kweetle KT-24 6 kW Point-of-Use Tankless Water Heater is a point-of-use electric tankless rated at 6 kW on 240 volts.
Expect about 0.6 GPM with cold winter water (a 70°F rise) and 0.9 GPM when the inlet is milder (45°F rise); that is less than one 2 GPM shower in January. Try your own inlet temperature.
At 240 volts 6 kW is about 25 amps (the listing states 27 A). The maker calls for 30A double-pole circuit breaker. The requirement calculator shows it at 208 V too; an electrician confirms the panel.
Small units like this suit one sink or a low-flow shower close by; at a kitchen sink's 1.5 GPM the water won't rise as far.
Listed details: connections: 1/2" npt; material: Acrylonitrile Butadiene Styrene, Aluminum, Glass; model: KT-24.
The listing gives dimensions of 8.7 in (W) x 8 in (H).
