How much hot water can it deliver at once?

Eemax rates it for 1 shower and 2 sinks at the same time in colder climates, and 3 showers and 2 sinks in warmer climates. Actual output depends on the incoming groundwater temperature.

What electrical service does it need?

It requires 240 volts, three 40-amp double-pole breakers and three 8 AWG wire runs. Confirm your panel capacity with a licensed electrician before buying.

Does it work in cold climates?

It works, but cold incoming water lowers the flow it can heat. In cold groundwater areas expect it to handle fewer fixtures at once than in warm regions.

How is the temperature set?

Temperature is set digitally in 1 °F increments from 80 °F to 140 °F. There is no tank to store hot water, so it heats only as water flows.

What connections does it use?

It uses 3/4-in NPT water connections and mounts on wall brackets. It activates at a flow of 0.3 GPM.

Is it a good fit versus a gas tankless unit?

It avoids gas lines and venting, which helps where those are impractical. The trade-off is a very large electrical draw that many homes cannot support.
