What it delivers
The VancEpic RE27K 27 kW Electric Tankless Water Heater is a whole-house electric tankless rated at 27 kW on 240 volts.
Expect about 2.6 GPM with cold winter water (a 70°F rise) and 4.1 GPM when the inlet is milder (45°F rise); that is 1 shower at 2 GPM in January. Size it to your fixtures.
At 240 volts 27 kW is about 112 amps. A licensed electrician confirms the panel, the service and the wire before it goes in.
It skips venting entirely, but the amps are the hurdle: check the panel before the plumbing.
