What it delivers
The WINTEMP YQ-WN8K 8 kW Point-of-Use Tankless Water Heater is a point-of-use electric tankless rated at 8 kW on 240 volts. Its listing gives a maximum flow of 1.9 GPM.
Expect about 0.8 GPM with cold winter water (a 70°F rise) and 1.2 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 8 kW is about 33 amps (the listing states 33 A). The maker calls for 40A DP breaker. The requirement calculator shows it at 208 V too; an electrician confirms the panel.
It's meant for a single fixture near the unit: it saves the wait for hot water there rather than heating a whole house.
Listed details: connections: 1/2" npt; material: Acrylonitrile Butadiene Styrene; model: YQ-WN8K; warranty: 2-year.
The listing gives dimensions of 9.7 in (W) x 14 in (H) and a weight of 7.9 lb.
Warranty, per the listing: 2-year.
