Real-World Performance: How It Feels to Use Wiser
Everyday Heating Control
The Wiser Home app delivers a smooth, intuitive experience. You can adjust room temperatures, apply preset modes like “Away” or “Eco,” and instantly override schedules with a Boost function. Users on Trustpilot frequently mention how "easy and stable" the app is, even for first-time smart home adopters.

Comfort & Eco Modes: Smarter Efficiency
Wiser learns how your home heats and cools. Comfort Mode ensures target temperatures are hit on time, while Eco Mode conserves energy by reducing overshoot. Combined with OpenTherm, this reduces inefficient on/off boiler cycling.

Installation & Compatibility
Easy DIY Installation
Wiser is designed for UK DIYers. If your existing thermostat uses the standard backplate, the Heat Hub clicks straight in — no rewiring. The wireless thermostat pairs over RF and comes with a stand or wall-mount option.
Setup takes under an hour for most homeowners.
Boiler Compatibility
Fully Compatible Brands:
Ideal, Baxi, Vaillant (OpenTherm models), Worcester Bosch, Glow-worm
Not Compatible With:
Gravity-fed systems or proprietary controls (consult a heating engineer)
Tip: Check if your boiler supports OpenTherm for full modulation benefits.
Expandability: Multi-Zone Heating That Pays for Itself
Easy DIY Installation
You can add up to 16 heating zones using Drayton’s smart TRVs. These TRVs replace standard radiator valves and sync with the Wiser hub.
Unlike Hive or Tado, Wiser’s TRVs are £45–£50, making full-home expansion affordable.
Why It Matters: Heating only the rooms you're using helps lower bills and reduce wasted energy — especially useful in larger homes or households with irregular occupancy.
Energy Efficiency & Boiler Plus Compliance
Wiser exceeds the UK’s Boiler Plus standards, offering:
- Load compensation (via OpenTherm)
- Scheduling & remote control
- Smart features without paywalls
While Drayton doesn't publish exact savings, typical users report noticeable efficiency gains. Real results depend on usage patterns and home insulation.
