This valve set in anthracite by designer brand Eucotherm gives wall-fed radiators a clean, streamlined look while letting you fine-tune the heat in every room: the corner bodies tuck pipework tight to the wall for easier cleaning and a neater finish, the thermostatic head and matching lockshield drop straight onto standard 15 mm compression × ½″ BSP connections so they’ll work with almost any hot-water radiator, not just Eucotherm models, and the numbered dial automatically holds your chosen temperature—tests for BEAMA show valves like these can cut heating energy use by roughly 18% across a UK season. A tough RAL 7016 anthracite powder coat resists knocks, moisture and UV fade for years of everyday use, and the set arrives as a ready-matched pair with a reassuring two-year manufacturer’s guarantee.
