Ener-J Smart WiFi Radiator Thermostat – Digital TRV for Multi-Room Heating Control, Alexa & Google Home Compatible

REVOLUTIONISE YOUR HOME HEATING WITH ZONAL CONTROL

Stop heating the whole house when you’re only using one room. The Ener-J Smart WiFi Radiator Thermostat (TRV) allows you to transition to a high-efficiency zonal heating system. By controlling each radiator individually via the ENERJSMART app, you can ensure your home office is warm during the day and your bedroom is perfectly cooled for sleep—all while significantly reducing your energy consumption.

SEAMLESS INTEGRATION & VOICE CONTROL

Upgrade to a truly connected home. This smart valve is fully compatible with Amazon Alexa and Google Assistant, allowing you to adjust temperatures with simple voice commands. Whether you’re snuggled on the sofa or heading home from work, you can monitor and manage your heating from anywhere in the world, ensuring you never "heat the street" or return to a cold house again.

SMART SAVINGS WITH OPEN WINDOW DETECTION

In 2026, every watt counts. Our TRV features intelligent Open Window Detection; if the valve senses a sudden drop in room temperature (from an open door or window), it automatically shuts off the heating to prevent energy waste. Combined with a fully programmable 7-day schedule, this "set-and-forget" device can help you save up to 30% on your annual heating costs.

DURABLE, SAFE, AND BUILT TO LAST

 Designed for the modern UK household, the Ener-J Smart Valve includes an Anti-Scale function that automatically cycles the valve to prevent mineral buildup and a Frost Protection mode to protect your pipes during freezing winters. With a built-in child lock and a sleek, minimalist design, it is the safest and most efficient upgrade for any standard radiator system.
