Our take on the Electric Tankless Water Heater 27kW 240V

This is a 27kW, 240V electric tankless water heater that mounts on a wall and heats water on demand instead of storing it in a tank. At full draw it delivers roughly 4.5 gallons per minute at a 60°F rise, enough for one shower plus a sink, and its 99.8% rated efficiency means almost all the power goes into the water. It needs a dedicated 240V circuit with about 113 amps of capacity, so a 125A panel and heavy-gauge wiring are usually required. No price was supplied for this listing, so compare current offers across stores before buying.

Questions and answers

Is 27kW enough for a whole house?
In a warm climate it can run a shower and a sink together. In cold regions with 40°F inlet water, expect one shower at a time, or step up to a larger unit.
What wiring and breaker does it need?
It draws about 113 amps at 240V, so it needs a dedicated circuit with a 120A or larger breaker and heavy-gauge copper wire. Most homes need a panel upgrade first.
How many gallons per minute does it produce?
About 4.5 GPM at a 60°F temperature rise, less in colder water and more in warmer water. Check your incoming water temperature before sizing.
Can it replace a 40-gallon tank heater?
Yes for households that use hot water one fixture at a time. Homes with simultaneous hot showers and appliance use may prefer a larger unit or a tank.
What is in the box?
Typically the heater, mounting bracket and hardware, and an installation manual. Plumbing fittings and the electrical disconnect are usually sold separately.
When is it cheapest?
Tankless heaters tend to dip during spring and summer and around major sales events. Track the price history and buy when it falls below its recent range.
