CONSTANT HOT WATER SUPPLY

The water heater will achieve and maintain 

the water temperature set on the digital 

display automatically irrespective of 

changing water flow and temperatures

TEMPERATURE MEMORY 

FUNCTION

The CPU of the controller will remember 

the temperature settings from the 

previous use, improving the reaction 

time upon start up. 

EASY OPERATION

Simplicity of adjusting the temperature 

of the hot water by 1°C increments at the 

touch of a button.

PILOT IGNITION

The pilot burner will automatically ignite 

first, then the main burner. The pilot will 

then go off avoiding excessive gas usage.

CAN BE USED TO BACK UP 

SOLAR GEYSERS 

Use this gas geyser in conjuction with 

our solar to gas valve to boost your solar 

water temperature in the winter months or 

colder, cloudier summer days.

FLAME OUT SENSOR

This is designed to automatically cut off 

the gas supply should the flame/ burner 

unexpectedly extinguish or the sensor no 

longer detects a flame.

LOW WATER PRESSURE  

START UP

The appliance will activate from a 

water flow of 3lt/min.  This makes 

it suitable for low water pressure 

applications.

OVER PRESSURISATION/

FREEZING  PROTECTION 

The appliance will automatically protect 

itself by releasing pressure if the water 

supply is over 10 Bar (this should be 

manually set to lower pressures see page 

13).

AUTOMATIC GAS ADJUSTMENT

The appliance will automatically adjust its 

gas usage depending on the water usage, 

using less gas when you use less water, 

making the appliance more efficient.
