What it delivers
The EcoSmart ECO 8 Point-of-Use Tankless Water Heater is a point-of-use electric tankless rated at 8 kW on 240 volts. Its listing gives a maximum flow of 2.0 GPM.
Expect about 0.8 GPM with cold winter water (a 70°F rise) and 1.2 GPM when the inlet is milder (45°F rise); that is less than one 2 GPM shower in January. Try your own inlet temperature.
At 240 volts 8 kW is about 33 amps. A licensed electrician confirms the panel, the service and the wire before it goes in.
Point-of-use units go under or beside one sink, where a short pipe run means hot water in seconds.
Listed details: features: LED Display; material: Stainless Steel; model: ECO 8.
The listing gives dimensions of 8 in (W) x 11.5 in (H) and a weight of 4.8 lb.
Warranty, per the listing: Lifetime Warranty on electronics, exchanger and element. Warranty only covers cost of heater; does not cover labor or any incidental damages.
