Hot water manual or sensor activated pumping system Demand-activated heated water pumping system for use in a dedicated heated water recirculation line. WMTS-464  Hot water manual or sensor-activated pumping systems 2016
Heated water circulating device Plastics-bodied heated water circulating devices for use in a dedicated heated water recirculation line. WMTS-472 Heated water system recirculation device 2016
Leak protection device Devices specifically designed to detect leaks and isolate the water supply to heated water systems utilised in association with a safe tray WMTS-476 Heated Water Systems – Leak protection device 2016
Thermal switching valve Metallic-bodied thermal switching valves intended to automatically switch the flow of water to one of two outlets, depending upon the temperature of the inlet water. Thermal switching valves are required to operate at—
  1. continuous operating temperature not exceeding 85°C and 99°C under emergency conditions; and
  2. continuous working pressure not exceeding 1400 kPa.
WMTS-481 Thermal switching valves 2016
Heated water system cold water recovery device Water recovery device installed in the heated and cold water supply systems. The device transfers water as the first flush in a heated water line to be stored and used back in the cold water supply system or diverted to be used for other purposes. WMTS-475 Heated Water Systems – Cold water recovery device 2016
Plate heat exchangers Plate heat exchangers intended to be used in heated water supply systems for the indirect heating/cooling of water in a plumbing system. These products are components of a water heating/cooling system and designed in various configurations including number of plates, plate design and size in order to suit the installation. They may be single or double wall construction and function with a heat exchange fluid in the primary circuit and water in the secondary circuit. WMTS-528 Plate heat exchangers – Indirect heating/cooling of water in a plumbing system 2021
Geothermal energy heat pump system for home air conditioning and supplementary potable water heater   Geothermal system for air conditioning and storing energy in the water contained in a storage tank. During the cooling period, heat extracted from the ambient by the system is stored in water, and the heat transfer is facilitated by a stainless steel heat exchanger. The water is stored in an electric storage water heater. When the temperature in the tank gets to 60 degrees celsius, heat transfer from the refrigerant to the waterside is stopped by de-energizing a pump that transfers water from the storage tank to the heat exchanger and back to the storage tank. The Water Mark Certification is only for the components covered under the Plumbing Code of Australia (PCA). WaterMark Certification shall not be used to cover off on components that may lie outside the PCA scope, such as refrigeration equipment.AS 3498 Water heaters and hot-water storage tanks2020
