Drayton launched the Wiser 2nd Generation Radiator Thermostat on 27 August 2026, expanding its Wiser 2nd Generation range of smart TRVs and smart heating controls1.
The company, which describes itself as one of the UK's leading heating control brands and part of Schneider Electric, said the new device strengthens its Wiser 2nd Generation smart home ecosystem1. Drayton states it has designed and manufactured products for energy-efficient domestic heating systems for over 75 years1.
"We've strengthened our growing Wiser 2nd Generation smart home ecosystem with the launch of the new and improved Wiser 2nd Generation Radiator Thermostat, delivering quieter operation, improved compatibility and an enhanced user experience for installers and homeowners alike"
The announcement gives no technical specification for the thermostat. Output figures, valve compatibility lists, radio protocol details, battery life and price have not been reported1. Drayton says the wider Wiser 2nd Generation range is available in merchants, and directs readers to its Wiser smart heating controls site1.
The launch sits alongside other Drayton news. On 2 September 2026 the company said its Digistat thermostat, which it calls the go-to thermostat for social housing, now supports Punjabi Gurmukhi in its Bluetooth-connected local app control1. On 1 September 2026 it noted that the government's electricity VAT cut takes effect from October 2026, and set out what that means for installers, homeowners and demand for more efficient heating and electrification1. Drayton also promoted its presence at InstallerSHOW 2026 on stand 5B52, with training, product demonstrations and installer rewards1.

Why it matters for households
A smart TRV replaces the manual valve head on an individual radiator and lets that radiator be controlled separately from the rest of the house, usually from an app or a schedule. That room-by-room control is the mechanism by which a household heats only the rooms it is using, rather than the whole home at one temperature. Drayton's claim of quieter operation matters in bedrooms and living rooms where a motorised valve head can be audible; its claim of improved compatibility matters where an existing valve body is being reused rather than replaced.
For a home's energy independence, the practical question is how far a thermostat of this kind reduces the gas or electricity a household buys, and how far it shifts demand away from peak periods. Drayton's announcement does not quantify any saving, and no independent test result for this product has been reported1. The site's guide on whether heating controls save money covers the evidence position generally, and the guide on heating controls with time-of-use tariffs covers how zone control interacts with time-shifting tariffs. Households weighing Drayton against other systems can compare the wider field of smart thermostats and the Drayton range.
What happens next
Drayton says the Wiser 2nd Generation range is in merchants now1. The electricity VAT cut it flagged takes effect from October 20261. No release date, price or specification for the new radiator thermostat beyond the launch date has been reported1.
