Thermostatic Mixing Valves

Did you know hot water can burn like fire? It can take as little as 1 second to receive third degree burns if exposed to hot water between 65 and 80 degrees celsius.

Thermostatic mixing valves (TMV’s) automatically calculate the input flows of hot and cold water to ensure an output with a constant temperature. Australian wide legislation has been enabled through AS/NZS 3500.4:1997, for hot water control and the safe delivery of hot water for ablutionary outlets in all buildings.

This legislation requires hot water to be delivered to sanitary fixtures at a temperature no greater than 50 degrees Celsius in domestic applications and 45 degrees Celsius in applications such as:

  • Early childhood centres
  • Primary and Secondary schools
  • Hospitals
  • Nursing homes and similar facilities for youth, aged, sick and disabled persons.

With hot water required to be stored at a minimum temperature of 60 degrees Celsius to prevent the growth of Legionella bacteria, TMV’s are a purpose built solution for the delivery of controlled temperature hot water for ablutionary purposes.

TMV’s are required to be installed and serviced in accordance with National Plumbing and Drainage code AS 3500 in conjunction with any manufacturers, local and state requirements. TMV’s require servicing and maintenance at intervals no greater than 12 month unsder the current legislation.

Central Queensland Plumbing’s technicians are compliant with all manufacturers, local and state requirements for the installation and servicing of TMV’s. CQP offer a fixed rate service agreement to customers to ensure regular and correct servicing of TMV’s as required buy all authorities.
