Drayton Wiser Smart Thermostat Kit 1: what owners actually say
Owners praise Wiser's value and smart home integration, but installation difficulty depends heavily on the age of your existing heating system
What owners complain about
- Hub reliability FEW
One owner reports their hub simply died, requiring a replacement swap
- Difficult with old radiator valves SOME
Owner with 'archaic 80's half seized lockshield valves' found the install far from the 'easy DIY' claimed; straightforward only if you have modern TRVs on a recently installed system
- Non-standard wiring complicates install SOME
Owners report non-standard wiring setups that differ from what installation guides show, requiring extra research and adjustment
- Discount codes expire fast SOME
Multiple owners mention seeking out promo codes for significant savings (£90–£334), but one noted the code 'didn't last long' after missing it
What owners love
- Great value vs. competitors
Owners explicitly call it 'great value compared to some of the other systems out there' after 1–2 years of use
- Works reliably long-term
Owner with 1–2 years of use reports it 'works very very well' with no issues mentioned
- Smart home integration
Owners successfully link it to Google Home and Alexa for voice control and remote switching on/off away from home
- Genuinely DIY-installable
Multiple owners completed the install themselves and found it 'not as scary as I thought,' especially when a backing plate was already in place
Surprising patterns
- Owners are reselling their old Honeywell units on eBay and nearly recouping the full cost of the Wiser system without TRVs
- The system works fine as a basic smart thermostat without upgrading to smart TRVs — owners use it that way and add TRVs later only if desired
- The 40% off promo code appears to be a major purchase trigger, with one owner saving £334 and another £90 on TRVs alone
WHO SHOULD SKIP IT
Owners of older heating systems with 1980s-era seized lockshield valves or non-standard wiring will likely face a frustrating installation far beyond the 'easy DIY' marketed experience
