What it delivers
The Titan N-100 10.8 kW Electric Tankless Water Heater is a compact electric tankless rated at 10.8 kW on 220 volts. Its listing gives a maximum flow of 2.0 GPM.
Worked out from its input, it delivers roughly 1.6 GPM when the water only has to rise 45°F, and 1.1 GPM at a 70°F winter rise: less than one 2 GPM shower in summer, less than one 2 GPM shower in winter. Size it to your fixtures.
At 220 volts 10.8 kW is about 49 amps. A licensed electrician confirms the panel, the service and the wire before it goes in.
No flue, no gas line and a compact box on the wall; the trade-off is that a cold winter inlet cuts its flow sharply.
Other listed details: features: Most efficient and practical product of its kind on the market; material: Titan; model: N-100.
The listing gives dimensions of 5 in (W) x 7 in (H).
