What it delivers
The Camplux TEW27 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. Check your house in the planner.
At 240 volts 27 kW is about 112 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.
Listed details: features: Instant hot water, Overheat Protection; connections: 3/4" npt; material: Alloy Steel; model: TEW27.
The listing gives dimensions of 13.12 in (W) x 17.12 in (H), a weight of 9.2 kg and mount kit in the box.
