The HEX250 system will deliver a constant output temperature of 60°C. To further enhance the efficiency of the HEX250 system, Rinnai has utilised an innovative control system which adjusts the temperature of the heated water to reflect the consumable water demand. It does this with an accurate temperature sensor, therefore reducing the amount of start ups each Continuous Flow unit has to complete. The water heaters have modulating burners which match the output of the heater to the hot water demand. The reduction in start  ups prolongs the life of the heat source and reduces the start up gas consumption.
