Manual Radiator Valves

A manual radiator valve remains either on or off. Manual valves need to be physically rotated by hand to increase or decrease the amount of hot water flowing into your radiator.

Thermostatic Radiator Valves

A thermostatic radiator valve or TRV is self-regulating, and controls the temperature of the radiator by changing the amount, or flow, of hot water into your radiator.

Pipe Shrouds

Pipe shrouds are used to cover the regular copper pipework of your heating system and to complement your radiator and valves.

Wall Stays

Most cast iron radiators require at least one wall stay to safely hold it to the wall. Radiators over 10 sections require at least 2 wall stays.
