How many smart radiator valves should you install?

Room-by-room heating

You do not need to equip every radiator from day one. The right number mainly depends on the rooms you actually use and the temperature differences you need.

Key takeaway: start with rooms where fine control truly changes comfort: bedroom, living room, office or rooms used only occasionally. You can expand later.

Which rooms should come first?

Bedroom

Different comfort needs in the evening, at night and in the morning.

Living room

The main living area, often used at regular times.

Office

Variable use, especially for remote work or shared spaces.

How many depending on your home?

Studio or small apartment: one or two valves may be enough.
Apartment with bedrooms: equip the living room and bedrooms according to usage.
Family house: start with living areas and bedrooms.
Irregular schedules: prioritize rooms occupied at changing times.
Central heating with a thermostat: valves can complement global control.

NéoDom tip:

Make a quick floor plan and sort rooms into three groups: often used, sometimes used, rarely used. It gives a reliable first answer.

Frequently asked questions

Do I need one valve per radiator?

To control a radiator precisely, yes. But not every radiator has to be a priority.

Can I start with one valve?

Yes, it is a good way to test the benefit in an important room.

Do I need a hub for several valves?

It depends on the protocol. Many Zigbee valves require a compatible gateway.

Conclusion

The right number of smart valves depends on your rooms, not a fixed rule. Start with the most useful zones, check radiator compatibility, then expand gradually.
