Where should the Hot Water Cylinder Sensor be located ?
Standard practice is to mount the sensor on the side of the cylinder and about eighteen inches above its base, but this does not of course measure the temperature of the water that may be drawn off by a tap at any particular time. The relationship of the tap water temperature to the sensor reading will be affected by the size and type of cylinder used, and to a lesser extent by the fixing method chosen for attaching the sensor to the cylinder. In most cases, the sensor will never be secured to the bare metal of the cylinder, but simply secured in a hole cut in the insulation material and held in place with the strap that is provided with the sensor. With Megaflow systems, sealed or unvented hot water cylinders and thermal storage systems, the sensor is normally fitted within the covered space provided for a thermostat on the side of the unit. Where a thermostat is already installed, this should be left in place and, wherever possible, wired in series with the DCD provided sensor. Furth
