Since 1868, when the first instantaneous water heater was patented, we have witnessed a long evolution in the heating of water. With each innovation, safety, efficiency and convenience have incrementally improved, but the fundamental principles have remained the same.
A supply of cold water accumulates in a tank. This is heated, either by electric elements, or a coil of pipe through which water from a boiler transfers heat, which warms the tanks contents.
Although the method of heating hasn’t changed, the current concerns regarding water scarcity and the cost of energy, means control has become increasingly important to ensure efficient consumption of both commodities.
Prefect Controls have been working closely with cylinder manufacturer, Gledhill, to produce a product that combines the latest tank technology with state-of-the-art monitoring, measuring and management.
The Irus SMART tank is factory-fitted with high-grade long-life titanium elements. It leaves the production line pre-plumbed and pre-wired, this reduces installation time, leaving just the cold-water supply, output feeds and wiring to the mains to connect.
The brain of the tank is the control box. This is pre-wired to the elements; water meters; probes; sensors; and optional leak detection equipment.
Two integrated water meters monitor supply in, and output to, the hot water system. They provide accurate data on the volume of water being used. Additionally, by monitoring flow, should a tap or shower be left running, an alert is sent to managers.
In-built pockets at optimum alignment with the elements contain probes that monitor water temperature at the tanks core, providing precise data for controlling heating patterns.
The Tundish sensor monitors any throughput, and alerts that hot water is being wasted. Sensors attached to the cold inlet and hot outlet, monitor the temperature of water entering and leaving the tank. While another input, with the addition of a leak sensor, will detect seepage from pipework and inform of leak intensity. The environmental conditions within the vicinity of the tank are also recorded including, humidity, light and sound pressure levels.
The SMART tank connects to Prefect’s Irus Central Control system, and the data is displayed on the dedicated internet portal. Managers control tanks remotely and, gather information without the need to visit individual flats or tank cupboards. A recent installation of 39 tanks shows energy savings of 17.5% over a 3-month period.
