What it delivers

The Eemax PR013240 13 kW Electric Tankless Water Heater is a compact electric tankless rated at 13 kW on 240 volts.

Expect about 1.3 GPM with cold winter water (a 70°F rise) and 2.0 GPM when the inlet is milder (45°F rise); that is less than one 2 GPM shower in January. Size it to your fixtures.

At 240 volts 13 kW is about 54 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.
