Our take on the GE 27.0kW Self-Modulating Whole-Home Tankless Electric Water Heater

The GE 27.0kW Self-Modulating Whole-Home Tankless Electric Water Heater is a high-capacity electric tankless unit designed to supply hot water for an entire home. It delivers instant hot water with digital temperature control from 86°F to 140°F and self-modulating technology that adjusts power to demand. However, its 112.5-amp draw requires multiple dedicated circuits and a heavy electrical service, which can add significant installation cost. It suits homeowners with sufficient electrical capacity who want endless hot water and space savings over a tank.

Questions and answers

How much electrical capacity does this water heater need?
It draws 112.5 amps at 240 volts, so it typically requires a 120-amp dedicated service or multiple smaller circuits. Many homes need an electrical panel upgrade to support it.
Can it handle a whole house with multiple showers running at once?
Yes, its 27 kW capacity is designed for whole-home use, but simultaneous high-flow use in cold weather may reduce temperature stability. It performs best in warmer climates or with lower flow rates.
What is the temperature range and is it adjustable?
The digital thermostat adjusts from 86°F to 140°F, letting you set a comfortable temperature. It also has overheat protection for safety.
Does it come with a pressure relief valve?
No, a temperature pressure relief valve is not included. Check local plumbing codes, as one may be required for installation.
Is this suitable for cold climates?
It can work in cold climates, but incoming water temperatures below about 50°F may reduce the achievable temperature rise at high flow rates. Preheating or lower flow may be needed.
