Our take on the Mizudo 14kW 240V Electric Tankless Water Heater

The Mizudo is a 14 kW point-of-use electric tankless heater that draws up to 59 A at 240 V on a single 63 A breaker with 6 AWG wiring. It heats water on demand, so there is no tank to run out and no standby loss, and the 14.3 x 9.6 x 2.8 inch case mounts on a wall in tight spaces. A digital display and touch panel set the outlet temperature, and it is aimed at 2-3 fixtures rather than a whole house. At this power level it suits hand sinks, a shower in a warm climate or a small apartment; it cannot match the flow of larger 18-27 kW units or gas tankless heaters feeding a full house. Owners of similar 14 kW units report warm rather than hot showers in cold inlet water and a real electrical install cost.

Pros
  • Heats on demand with no tank to run out
  • Compact wall-mount case fits tight spaces
  • Digital display and touch temperature control
  • No standby storage loss, unlike a tank heater
  • Overheating and leak protection built in
Cons
  • 59 A draw needs a dedicated 63 A breaker and 6 AWG wire
  • 14 kW limits flow, so cold inlet water means lukewarm output
  • Not enough for a whole house with simultaneous hot-water use
  • Hardware and install cost can rival the unit itself
  • No tank means no hot water during a power outage

About the Mizudo 14kW 240V Electric Tankless Water Heater

The Mizudo 14kW 240V is an electric tankless water heater. It heats water as it flows through the unit, so there is no storage tank to fill and wait on. It is suited to 2 to 3 points of use throughout a house.

The heater has a digital display and a touch panel for setting the hot water temperature. Its compact size lets it be installed in small spaces such as on a wall, in a garage or in a basement. Because it does not store hot water, it has no standby storage loss.

Safety features include overheating protection and leak detection. The internal water and electrical circuits operate separately. An instruction manual is included for installation.

Questions and answers

Will 14 kW run a whole house?
No. It is rated for 2-3 points of use. Running a shower and a sink together is fine in warm climates, but simultaneous use in cold inlet water will drop the temperature.
What electrical setup does it need?
A dedicated 240 V circuit on a single 63 A breaker with 6 AWG/2 wire. The unit draws up to 59 A, so a licensed electrician should confirm your panel can spare that capacity.
How does it compare with a tank water heater?
It saves space and avoids standby heat loss, but a tank gives hot water during outages and handles multiple fixtures at once. Choose tankless for space and efficiency, a tank for whole-house volume.
Does it work with cold inlet water?
Output temperature depends on flow and incoming water temperature. In cold climates, keep flow low or expect warm rather than hot water at high flow rates.
What is in the box?
The heater and a detailed instruction manual. Mounting hardware, the breaker and the 6 AWG wire are not included and must be bought separately.
Can I install it myself?
Only if you are qualified for 240 V work. The 63 A circuit and 6 AWG wiring are not a typical DIY job, and many local codes require a licensed electrician and a permit.
Where is the Mizudo 14kW 240V Electric Tankless Water Heater cheapest?
