Drayton expands its Wiser smart heating range with a 2nd Gen radiator thermostat, offering precise room control and multi-system compatibility.
Drayton has introduced the next-generation Smart Radiator Thermostat to its Wiser smart home portfolio. The updated unit expands the brand's 2nd Generation heating control ecosystem, providing tighter room-by-room temperature regulation alongside installation upgrades aimed at heating engineers, electricians, and homeowners.
Designed to integrate into existing setups, the upgraded radiator valve maintains full backward and forward compatibility, working alongside both 1st Generation and 2nd Generation Wiser systems. The focus of the update centers on improving control precision, simplifying the physical installation process, and refining day-to-day operation for end users managing zoned heating.
What does this mean for a UK tradesperson or DIYer actually buying this kit — does it change what they should pay, buy, or watch out for?
For electricians and heating engineers, full backward compatibility means you can upgrade individual zones on older Wiser setups without forcing customers into buying a completely new hub or replacing working hardware. When sourcing from merchants like Screwfix or Toolstation, look out for whether stock is 1st Gen or 2nd Gen, as existing client systems will accept either. While pricing updates follow manufacturer rollout, cross-generation support helps protect customer budgets by allowing incremental system expansion rather than requiring full-system overhauls.
The updated thermostat offers a straightforward replacement option for standard thermostatic radiator valves (TRVs). Installers stocking up for heating season should note the following operational considerations:
