Diaphragm Gas Geysers (8L–20L)
| Indoor or Outdoor Use
Units can be installed indoors (with a flue to the outside) or outdoors under protective cover. Each geyser includes a flue sensor that automatically shuts down the unit within 4 minutes if the flue is blocked or missing—meeting legal safety standards.
| How It Works
• Powered by Type D torch batteries
• When you open the hot tap, water pressure activates the diaphragm, triggering ignition and gas flow to the burners
• Optimal performance requires constant water pressure between 1.8 and 2.5 bar
• For water lines longer than 8m, some heat loss may occur
• Always choose the correct size geyser for your needs
| Choosing the Right Size
A 16L geyser delivers up to 16 litres of hot water per minute, raising incoming water temperature by 25–30°C. For example, if your incoming water is 20°C, you’ll get 45–50°C output. Want hotter water? Simply reduce the flow—but note this also lowers litres per minute.
| Available Sizes
6L, 8L, 10L, 12L, 16L, and 20L

Type B - Zero Start Geyser
This unit can be installed inside (needs to be flued to the outside) or can also be installed outside under protective cover. This unit is fitted with a flue sensor mounted on the flue diverter. The function of this sensor is to shut the unit down within 4 minutes by law if the flue is blocked or the flue is not fitted.
How it works:
- Ignition is through Type D torch batteries
- Open hot water tap - the water pressure pushes the light weight magnetic floater up and activates the geyser by signalling to the electronic box that there is spark and that the gas solenoid valve must open the gas to the main burners
- This type of geyser operates on low water pressure and is also less sensitive to mixer taps
- Once installed and you are ready to set the temperature, start by doing the following:
1 - set the gas knob to minimum gas
2 - set the water inlet valve to maximum water flow, and open your tap
3 - set the correct water temp by slowly increasing the gas
- This makes the zero start unit the most efficient on the market
- To determine the size required is different to the diaphragm units. Simply do the following to assist you in choosing the correct size. This exercise is only if the water pressure is low:
1 - measure the water flow per minute at two to three different taps in and around the house. Measure one tap then also open multiple taps to see if the waterflow rate per minute stays the same.
2 - once you have determined the waterflow per minute you choose the size geyser according to that.
Example: If you get around 10L per minute then you install a 9L zero start unit. Do not install an over-sized geyser as it will over-heat and shut down.
Available in the following sizes: 9L, 12L, 14L & 18L

Constant Temperature Geyser
This unit can be installed inside (needs to be flued to the outside) or can also be installed outside under protective cover. This unit is fitted with a flue sensor mounted on the flue diverter. The function of this sensor is to shut the unit down within 4 minutes by law if the flue is blocked or the flue is not fitted.
How it works:
- The geyser has a temperature adjusting panel on the front cover for easy setting of the required temperature
- Ignition is through Type D torch batteries
- Open hot water tap - the water pressure pushes the light weight magnetic floater up (same as the zero start geyser) activates the geyser by signalling to the electronic box that there is spark and that the gas solenoid valve must open the gas to the main burners.
- The water will the heat up through the heat exchanger to your desired temperature. (as set on display)
- The proportional valve will then regulate the gas/water ratio to the keep the water at the constant temperature.
- The proportional valve ensures optimum performance at reduced LPG usage.

Type D - Fan Forced Geyser
Key Features:
- You can do additional keypads on one geyser
- Fan assisted - the fan assists by sucking out the burnt gas for cleaner combustion, therefore increases the energy output of the burners resulting in much lighter gas consumption.
- No need for a flue as it comes with a vented slot on the front cover.
- Very low on gas consumption
- Electric impulse ignition, ensures stable and fast ignition
- Constant temperature control as this unit is equipped with a proportional valve
- Low starting water pressure (100kpa)
- High power unit with considerable strong water output that can supply multiple water outlet points
Available in the following sizes: 12L, 20L & 28L
