There are numerous advantages to having one or multiple controllers connected to your hot water service when installed at your home or the office.

  • Energy saving: By adjusting the temperature to a lower level for example 42 degrees the gas burner does not need to work as hard to heat the water and therefore saves energy in only heating the water to the desired temperature.  If the water temperature is then required to be higher for washing dishes or doing laundry it can then be dialled up to 50 degrees.
  • Safety: Hot water can be extremely dangerous for young children and elder when we look at scalding.  The advantage of a temperature controller is that the waters temperature can be locked at a safe temperature.  For example, 40 degrees is considered not to be harmful and still acceptable for bathing.  By locking the water heaters temperature out at 40 degrees it will guarantee a safe environment for children and the elderly.
  • Fault finding: If a continuous flow hot water services is experiencing a problem the control pad will display an error code allowing our licensed technicians to easily diagnose the fault with the system and then allows us to have the system fixed.


Its also worth noting that older style control pads may not be compatible with upgraded water systems but in majority of the cases the existing wiring will be reusable making the upgrade process far less invasive then the initial installation.
