What it delivers
The WINTEMP YQ-WN27K 27 kW Electric Tankless Water Heater is a whole-house electric tankless rated at 27 kW on 240 volts. Its listing gives a maximum flow of 6.5 GPM.
Flow depends on how cold the incoming water is. Our estimate from its input: 4.1 GPM at a 45°F rise, falling to 2.6 GPM at 70°F, which is 1 shower at 2 GPM on a cold-climate winter day. Check your house in the planner.
At 240 volts 27 kW is about 112 amps (the listing states 113 A). The maker calls for 3 x 40 Amp double-pole (DP) breakers. A licensed electrician confirms the panel, the service and the wire before it goes in.
Electric tankless units need no venting and no gas, and work best where inlet water stays mild, because every degree of rise costs flow.
Also on the listing: features: LED Display, Overheat Protection; connections: 3/4" npt; material: Acrylonitrile Butadiene Styrene; model: YQ-WN27K; warranty: 2-Year.
The listing gives dimensions of 11.1 in (W) x 19.1 in (H).
Warranty, per the listing: 2-Year.
