What it delivers

The OVAS HOO HME-15 3 kW Point-of-Use Tankless Water Heater is a point-of-use electric tankless rated at 3 kW on 110 volts.

Flow depends on how cold the incoming water is. Our estimate from its input: 0.5 GPM at a 45°F rise, falling to 0.3 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 110 volts 3 kW is about 27 amps. The maker calls for 30A breaker. A licensed electrician confirms the panel, the service and the wire before it goes in.

Small units like this suit one sink or a low-flow shower close by; at a kitchen sink's 1.5 GPM the water won't rise as far.
