This listing is for 1x Tado supplied GIA-00 Giacomini and Roca Type Thermostatic Radiator Valve Adapter.

This will convert the radiator valve to a M30 x1.5mm male thread to allow the fitment of most M30 x1.5mm Smart Electronic Radiator Thermostats.

Allows the easy fitment of Honeywell Evohome HR92 HR91, Tado, Hive (with the Hive supplied M30 collar) and many other modern electronic TRVs. 

The adapter has a 22.6 mm clamp to fit Giacomini and Roca type Thermostatic Radiator Valves, it simply clips on to the radiator valve with no tools required. The threaded section of the adapter is 30mm x1.5mm

With your old head unclamped from the valve, please check your radiator valve has a 22.6 mm diameter head behind the large nut, as the adapter is only suitable for this type of radiator valve. See pictures for further details.

Further info is available on Tado’s website.
