Keeping your water temperature just how you like it in your domestic hot water cylinder or pipes is essential, and the L641B1004 Low Limit Pipe thermostat from Honeywell Home will play a key role in this.The L641B1004 is designed to be surface mounted on your domestic hot water cylinders and can be used to switch directly on a central heating circulating pump or boiler. Alternatively, this thermostat can operate on a spring return or motor open/motor close zone valves. Well suited to switching motorised zone valves, circulating pumps or boilers, this thermostat incorporates a bi-metallic temperature sensor and is double insulated for extra protection. The L641B1004 can be used with bare or pre-insulated cylinders, and installation is simple: just a plastic coiled wire is required for fixing. The Honeywell Home L641B1004 Low Limit Pipe Thermostat is perhaps the most cost-effective way in which to manage your water temperature at home.
