Abstract

A monitoring system for monitoring parameters of a fluid heater is disclosed. The heater comprises a storage vessel for storing heated fluid therein. The monitoring system includes a first sensor and associated first electrical metering circuitry, a second sensor and associated second electrical metering circuitry, and a control switch. The control switch is operable to adopt a first mode of operation in which the first electrical metering circuitry is activated and a second mode of operation in which the second electrical metering circuitry is activated. The monitoring system also includes a controller for causing periodic operation of the control switch so that it switches between the first and second modes of operation.
