Smart Water Heating Solutions
Upgrade your home with the ThermoMate ET140 (14kW). Designed for modern American homes, this self-modulating tankless heater delivers consistent hot water on demand while slashing your energy bills. Say goodbye to bulky tanks and cold showers.
Hard water is a heater killer. Unlike competitors that immerse heating elements directly in water (attracting scale and corrosion), ThermoMate employs an advanced design where the heating element is separated from the water tube.
The ET140 doesn't just blast heat; it thinks. It automatically adjusts energy consumption based on water flow and incoming temperature to maintain your exact setting.
Capacity depends on your inlet water temperature. The ET140 delivers up to 2.66 GPM in warm climates, perfect for whole-house use (1 showers simultaneously).
❄️ Northern US / Winter: Ideal for 1 shower + 1 sink (approx. 1.8-2.5 GPM).
☀️ Southern US / Summer: Ideal for 2 showers + 1 sink (approx. 3.0-4.4 GPM).
*Please check the map to ensure this unit meets your flow rate needs for your region.
"Hot water that lasts as long as you do. Fill deep soaking tubs without the water running cold halfway through."
Save up to 60% on water heating costs. Traditional tanks heat water 24/7 (even when you sleep). ThermoMate only heats when you need it.
Sleek, wall-mounted design releases floor space in your garage, basement, or closet. Dimensions: 15.35" x 12.83" x 2.89".
To ensure this unit works safely and effectively, your home must meet these electrical standards.
