The Mizudo 18kW is a whole-house electric tankless water heater rated for 2 to 3 points of use. It runs on 240V and draws up to 75A, so it needs two 40A breakers and two runs of 8 AWG wire. A digital display and touch panel set the temperature, and the slim 17 x 13 x 3.6 inch case mounts on a wall, in a garage or a basement. It competes with other 18kW electric tankless units on the same circuit demands; the real difference is installation cost and how much hot water your electrical panel can support.
