The white thermostatic straight valve by Eucotherm slips onto any floor-fed radiator with standard 15mm compression fittings and a ½ BSP tail, pairing a liquid-sensor TRV head with a matching lockshield in a durable, traffic-white powder coat (close to RAL 9016) over solid brass. The dial spans frost-protect to setting 5—roughly 7°C to 28°C—so it modulates flow automatically once your chosen room temperature is reached, guarding against frozen pipes and stopping wasteful overheating. Independently tested by BEAMA, the thermostatic head can cut radiator energy use by roughly 18% across a UK heating season, paying for itself quietly in the background every winter. Supplied as a colour-matched pair with a lockshield valve included, pipework stays neat and the aesthetic stays consistent. Backed by Eucotherm's two-year guarantee, this straight-body kit brings precision control, clean lines and a designer-grade finish to any compatible wet-system radiator. Shop now.
