How does it work ? When tap water (hot) is open the water flows through appliance, ignites the flame under the heat exchanger. Water flows through heat exchanger is heated instantly, when water flow stops appliance shuts the gas flow. The system ignites by two long life batteries, the ON/OFF switch indicates the system is On or Off (11 and 14ltr) If the batteries are almost running out, a red light flashes on the ON/OFF switch. (11 and 14ltr) If the flame knob is turned clockwise, it lowers the flame into the chamber hence the water temperature is lowered. If the flame knob is turned anticlockwise, the flame inside the chamber increases the water temperature. If the flow knob is turned clockwise, the flow will decrease and increases the water temperature. If the flow knob is turned anticlockwise, the flow increases and the water temperature decreases. 2. What sizes are there available and how much persons does this cover ? The below show the hot water flow capacities per minute. 11Ltr - Ideal for 1bathroom. 14Ltr - Ideal for 2 bathrooms used at the same time. 18Ltr - Ideal for 3 bathrooms used at the same time.

It is required that a 2.5 bar pressure pump is installed if water is supplied from roof tank. Water can be supplied from roof tank or from mains (minimum pressure of 2.5 bar). 5. What service can be done ? Batteries replacement as needed. Gas Cylinder replacement as needed. Other services needs to be done by our qualified Technicians (Contact Us). 6.
