The WINTEMP WN27 is a whole-house tankless electric water heater rated at 27 kW and wired for 240V. It heats water on demand to about 125°F, so a household doesn't run out of hot water the way it does with a tank. Self-modulating power adjusts draw to flow, and it adds Wi-Fi control plus overheat, dry-fire and leakage protection. It suits large homes with the electrical service to feed 27 kW; smaller homes and anyone without spare panel capacity should look at lower-kW models.
