Abstract

The invention provides a method of assessing remotely the temperature on the remote side of a barrier in the form of an insulated wall of a hot water cylinder (10), comprising applying to the near side (14) of the barrier a temperature measuring device (22) comprising a first temperature sensor (24) in contact with the near side of the barrier and a second temperature sensor (26) spaced from the first temperature sensor and separated therefrom by thermally insulating material (28), measuring the temperature (θ1) at the first temperature sensor and the temperature (θ2) at the second temperature sensor, and calculating from the measured temperature values the temperature (θU) on the remote side of the barrier, based on the thermal conductivity properties of the barrier (UB) and of the thermally insulating material of the temperature measuring device (UM). The invention also provides a hot water cylinder, a temperature measuring device for use with a hot water cylinder, and a kit of parts for retrofitting to a hot water cylinder.
