Hive Radiator Valves

The UK7004561 is sold as a Hive Smart TRV, which adds thermostatic control so the radiator holds a set room temperature, while the UK7004240 is the standard Hive Smart Radiator Valve and is the lower‑priced option. The TRV is useful if you want precise temperature control in a room such as a bedroom or nursery; the cheaper valve is good if you mainly want smart on/off control and group scheduling across several radiators. Both give access to room‑by‑room heating and smart group control, so pick the TRV where fine temperature regulation matters and the standard valve where simplicity and cost are your priority.

You fit a Hive valve to each radiator and set individual temperatures for each room so, the living room can be warmer than the spare bedroom. Smart group control lets you combine several valves into one group (such as "downstairs") so you can change all their settings with a single command or schedule. That means you can maintain a cosy lounge without wasting heat upstairs and still heat several radiators together when you want the whole floor warm.

By controlling heating room‑by‑room you avoid wasting heat where it is not needed, which reduces energy use. They are compatible with Hive Window Sensors so radiators can automatically turn off if a window is opened, preventing heat loss and unnecessary boiler cycles. Using targeted heating and automatic shut‑offs lowers fuel consumption and therefore cuts both bills and your household carbon footprint.

Yes, the valves include a child lock to prevent little hands from changing settings or turning radiators up accidentally. Because you can set and lock temperatures remotely or by group, you reduce the chance of overheating rooms or sudden hot surfaces. That combination makes them a sensible choice for homes with children or curious pets.

Start with the rooms where temperature control matters most: bedrooms, the living room and a home office are typical priorities. Fit a TRV where you need accurate temperature holding, a bedroom or nursery where you want a steady 16–19°C is a good choice, and consider standard smart valves for spaces you simply switch on and off, such as a rarely used dining room. That approach gives you the biggest comfort and energy savings with the fewest units.
