Drayton Wiser Smart Thermostat Kit Review
A modular, scalable British-designed smart heating system that allows for individual room control via TRVs.
Quick verdict
The Drayton Wiser system is a robust, cost-effective entry into smart heating that excels due to its modularity. While the base kit provides solid scheduling, its true energy-saving potential is only unlocked when paired with individual radiator thermostats to prevent heating empty rooms.

Frequently asked questions
Does this require a professional electrician?
If you have a standard UK wall plate, it is often a DIY swap. Otherwise, a professional should install the HubR.
Can I use it without the internet?
The system will follow its internal schedule if the Wi-Fi goes down, but you won't be able to change settings via the app.
Do I need the smart TRVs for it to work?
No, it works as a standard smart thermostat, but the specific 'energy-saving' zoning benefits require the TRVs.
How many zones can I have?
The Wiser system supports up to 16 different zones and 32 total devices.
