What it delivers

The Eemax EX160TC 16 kW Electric Tankless Water Heater is a compact electric tankless rated at 16 kW on 277 volts.

Flow depends on how cold the incoming water is. Our estimate from its input: 2.4 GPM at a 45°F rise, falling to 1.6 GPM at 70°F, which is less than one 2 GPM shower on a cold-climate winter day. Size it to your fixtures.

At 277 volts 16 kW is about 58 amps. Whether your panel can carry it alongside heating and cooking loads is an electrician's call.

It skips venting entirely, but the amps are the hurdle: check the panel before the plumbing.

Also on the listing: connections: 3/4 inch NPT; model: EX160TC.

The listing gives dimensions of 11 in (W) x 11 in (H), a weight of 8 lb and electric tankless product in the box.
