Our take on the KFFKFF 27kW Tankless Electric Water Heater

The KFFKFF 27kW is a whole-house electric tankless water heater built around a die-cast aluminum heating element. At 27kW it needs a large dedicated electrical supply, roughly 113 amps at 240V, so most homes need an electrician and possibly a service upgrade before it can run. It suits households replacing a tank heater where panel capacity allows, and it competes with brands like Rheem, EcoSmart and Stiebel Eltron on output and safety features rather than on smart controls or brand support.

Questions and answers

What electrical supply does the KFFKFF 27kW need?
It draws about 113 amps at 240V, so it needs multiple dedicated breakers and heavy-gauge wiring. Most homes need an electrician to confirm the panel can handle it.
Is 27kW enough for a whole house?
It can run a shower and a sink at once in a moderate climate. In cold incoming water or with several fixtures running, output drops, so size it against your ground water temperature.
How is it different from a tank heater?
It heats water on demand and takes up little wall space, with no tank to run out. The trade-off is a much larger electrical requirement than a tank unit.
Does it work with hard water?
The aluminum element resists scale, but the inlet filter and showerhead still need regular cleaning. In very hard water, scale buildup will shorten its life.
What maintenance does it need?
Drain the unit completely in freezing weather and clean the inlet filter regularly. Both steps are required to keep the warranty and performance intact.
Can I install it myself?
No. The current draw and plumbing connections make this a licensed electrician and plumber job in most jurisdictions.
Where is the KFFKFF 27kW Tankless Electric Water Heater cheapest?
At Walmart, for $263.99, as of our latest check.
