Duplex 2205 is a stainless-steel alloy designed to provide strong mechanical strength and corrosion resistance.
Omni X uses Duplex 2205 in its premium heat-pump cylinders and stainless-steel electric-storage range as a key durability feature.
Because the cylinder itself is corrosion-resistant stainless steel, the premium Omni X platform does not rely on the sacrificial-anode replacement schedule common to many glass-lined steel water heaters.
Omni X promotes its Duplex stainless heat-pump cylinders as not requiring conventional sacrificial-anode replacement.
That removes one common long-term service item found in many enamel-lined storage hot-water systems.
Omni X's Duplex stainless heat pumps use R290 natural refrigerant.
The heat pump extracts thermal energy from surrounding air and transfers that heat into the stored water rather than producing all heat directly through electric resistance.
R290 has very low global-warming potential compared with older synthetic refrigerants and is now widely used across newer-generation residential heat pumps.
Current Omni X Duplex heat pumps include smart Wi-Fi and LCD control.
Timer functions allow the heat pump to be scheduled toward periods when rooftop solar PV is generating, helping a household use more of its own solar electricity for water heating.
The storage tank then retains the heated water for later use, effectively storing some daytime solar generation as thermal energy.
Omni X promotes relatively low electrical demand across its premium heat-pump platform.
The published 420L specification lists maximum current of approximately 6A, while broader Omni X literature promotes standard 10A-compatible electrical connection on applicable models.
The exact circuit and connection method should still be confirmed against the selected model before installation.
Omni X also offers a separate lower-cost glass-lined all-in-one heat-pump range.
Current published capacities are 210L, 270L and 320L.
These systems provide a more affordable route into heat-pump hot water for customers who do not require the Duplex stainless tank used by the premium range.
Compact glass-lined heat pump for lower to moderate household demand.
FromMid-size glass-lined heat pump for typical family use.
FromLarger glass-lined system where extra storage is preferred without moving to the premium stainless platform.
From| Feature | Duplex Stainless Range | Glass-Lined Range |
|---|---|---|
| Current sizes | 180L / 250L / 340L / 420L | 210L / 270L / 320L |
| Tank construction | Duplex 2205 stainless steel | Glass-lined steel |
| Premium positioning | Yes | Lower-cost alternative |
| Conventional anode replacement | No | Check exact model requirements |
| Current manufacturer emphasis | Durability + low maintenance | Value + heat-pump efficiency |
Omni X is also unusual among newer heat-pump brands because it offers a complete stainless-steel electric-storage range.
Current capacities include 50L, 80L, 125L, 160L, 250L, 315L and 400L.
These systems do not use heat-pump technology. They heat the stored water directly with electric resistance, making them mechanically simpler but generally more electricity-intensive than a heat pump.
| Capacity | General application |
|---|---|
| 50L | Small point-of-use or very low-demand applications. |
| 80L | Small homes, apartments or limited hot-water demand. |
| 125L | Lower-demand residential electric storage. |
| 160L | Small to moderate household use. |
| 250L | Typical family electric storage. |
| 315L | Larger household or higher peak demand. |
| 400L | High-demand residential or selected commercial use. |
JR sizes stored hot water from actual household demand rather than simply matching the capacity of the system being removed.
Our starting allowances are approximately 40 litres per person per day for light use, 50 litres for average use, 65 litres for high use and around 80 litres for very heavy demand.
Best considered for couples, smaller homes and households with lower peak hot-water demand.
Strong middle ground for typical family households and moderate shower demand.
Better suited to larger families, multiple bathrooms and heavier morning or evening peaks.
Intended for very high household demand where a conventional 250L or 300L-class heat pump would leave insufficient stored reserve.
Current Omni X heat pumps are designed to work effectively with rooftop solar PV.
Wi-Fi and timer controls allow water heating to be scheduled into the middle of the day when solar production is usually highest.
This allows the hot-water tank to act as a form of thermal storage, using excess solar electricity to produce hot water that can be used later.
Omni X markets its heat pumps as using substantially less electricity than conventional electric storage because the heat pump transfers ambient heat rather than relying entirely on a resistance element.
Manufacturer material promotes savings of up to approximately 75% compared with traditional electric hot water under suitable conditions.
Actual savings depend on ambient conditions, tariff, solar PV, water use, temperature settings and the amount of backup heating required.
Current Omni X information for the premium Duplex heat-pump range lists a 10-year warranty on the storage cylinder.
Refrigeration and other major components are currently listed with five years warranty, the relief valve with two years and onsite labour with five years, subject to the manufacturer's warranty conditions.
Warranty terms can differ between product categories, so the exact warranty supplied with the selected Omni X model should always be checked.
