What it delivers
The VancEpic RE18K-C 18 kW Electric Tankless Water Heater is a whole-house electric tankless rated at 18 kW on 240 volts. Its listing gives a maximum flow of 0.5 GPM.
Flow depends on how cold the incoming water is. Our estimate from its input: 0.5 GPM at a 45°F rise, falling to 0.5 GPM at 70°F, which is less than one 2 GPM shower on a cold-climate winter day. Check your house in the planner.
At 240 volts 18 kW is about 75 amps. Whether your panel can carry it alongside heating and cooking loads is an electrician's call.
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; connections: 3/4" npt; material: Iron; model: RE18K-C; warranty: 2 Year Manufacturer.
The listing gives dimensions of 3.19 in (W) x 15.87 in (H) and a weight of 10.5 lb.
Warranty, per the listing: 2 Year Manufacturer.
