The Smartstart system works as follows

  • Before hot water is required, the user activates the Smartstart system by pressing the ‘preheat’ button on the water controller or by pressing the Manual Activation Switch. This activates the Smartstart system and the integral pump is switched on. Water flows from the pump and passes through the water heater. This in turn activates the water heater burner and water in the flow and return heating loop begins to heat. When the Smartstart control module senses that the water in the full length of the flow and return heating loop has been heated, the pump and water heater stops operating. The user opens the desired hot water outlet. Preheated water will be delivered from the flow and return heating loop to the outlet.
