A storage water heater heats water and keeps it in an insulated tank so it is ready when you need it. This makes the category particularly useful for homes that need a stored supply of hot water for bathing and other regular household use.
At Orient Electric, you can choose between different capacities, mounting formats, tank technologies and feature levels rather than using one model for every requirement.
Choose Your Geyser Capacity
Capacity is one of the first things to decide because it determines how much hot water the tank can hold.
| Capacity |
When to consider it |
| 6L |
A compact option when the hot-water requirement is relatively limited |
| 10L |
Suitable for lighter everyday household use |
| 15L |
A practical choice when regular bathroom use and showering require more stored water |
| 25L |
Better suited to higher hot-water demand or situations where more stored water is useful |
Don't choose capacity by family size alone. Your bathing pattern, shower duration, number of consecutive users, inlet-water temperature and available bathroom space also affect the right choice.
Orient Electric currently offers storage models across 6L, 10L, 15L and 25L, with several product families available in more than one capacity.
10L vs 15L vs 25L Storage Geyser
When two capacities both seem suitable, think about how the geyser will actually be used.
-
10L can work well when your hot-water requirement is on the lighter side and you want a smaller tank.
-
15L gives you more stored water for regular bathroom use and is a common step up when a smaller tank feels limiting.
-
25L makes more sense when the household has higher hot-water demand or when more stored water is needed for consecutive use.
Orient Electric's Aquator Neo and Aquanova Neo are currently available across 10L, 15L and 25L capacities, allowing you to stay within the same product family while selecting the tank size that fits your requirement.
Vertical or Horizontal Geyser?
The shape of the water heater matters when bathroom space is limited.
Vertical Storage Geysers
Vertical models are mounted upright and are the more common format for bathrooms with adequate vertical wall space.
Orient Electric offers vertical options such as Aquator Neo, Aquanova Neo, Enamour Classic Pro, Maverick, Ecoswift Pro and others.
Horizontal Storage Geysers
A horizontal model can be useful when vertical clearance is limited.
Aquaslim Horizontal is designed for this type of installation and is available in 15L and 25L variants, with left- and right-inlet configurations. It is also positioned for high-rise apartments and comes with free installation and connecting pipes.
Before ordering a horizontal or vertical geyser, check the mounting position, inlet/outlet arrangement, dimensions and service access available in your bathroom.
Storage Geysers for High-Rise Buildings
High-rise homes can have higher water pressure, so pressure compatibility should be checked before choosing a storage water heater.
Orient Electric has several models specifically positioned for high-rise use. Aquator Neo supports pressure up to 8 bar, while Aquator IoT and Evapro PC also with up to 8-bar pressure compatibility. Aquaslim Horizontal is also positioned for high-rise apartments.
For a high-rise installation, choose a model whose specified pressure rating matches your installation conditions. Do not assume that every storage geyser has the same pressure capability.
5-Star Storage Water Heaters
The BEE star rating helps you compare the energy-efficiency classification of eligible water heaters.
Orient Electric's range includes several 5-Star storage water heaters, including Aquator Neo, Aquanova Neo, Aquator IoT, Enamour Classic Pro, Maverick and Evapro PC. The exact rating should always be checked against the selected model and variant.
A higher star rating should be considered alongside capacity, wattage, usage and temperature settings when comparing electricity consumption.
Glassline and Polymer-Coated Storage Water Heaters
The tank construction is another important part of the buying decision, particularly in areas where water quality is a concern.
Glassline Storage Water Heaters
Aquator Neo uses an Ultra Diamond Glassline-coated tank with a thick magnesium anode. Aquanova Neo uses a Blue Diamond Glassline-coated tank with a magnesium anode. These models are designed with corrosion protection in mind.
Polymer-Coated Storage Water Heaters
Maverick uses a polymer-coated tank and is available as a 5-Star storage water heater. Enamour Classic Pro is another current polymer-oriented storage model, with a polymer body and corrosion-resistant nickel-coated copper heating element.
In hard-water areas, compare the tank coating, heating element, anode protection and warranty of the exact model.
Storage Geysers for Hard Water
Hard water can affect water-heater components over time, so construction and corrosion protection deserve more attention in such locations.
For example, Aquator Neo combines its Ultra Diamond Glassline tank with a thick magnesium anode, while Aquanova Neo uses Blue Diamond Glassline and a magnesium anode. Maverick uses a polymer-coated tank.
The right choice also depends on local water quality and usage, so use the product specifications and warranty terms of the selected geyser as your final reference.
Storage Geysers with Long-Term Warranty
Warranty coverage differs across the range, so it is worth comparing the tank, heating element and overall product warranties separately.
-
Aquator Neo currently carries a 7-year tank warranty, 6-year heating-element warranty and 2-year product warranty.
-
Aquanova Neo also carries a 7-year tank, 6-year heating-element and 2-year product warranty.
-
Aquator IoT provides 7 years on the tank, 4 years on the heating element and 2 years on the overall product.
-
Aquaslim Horizontal currently specifies 7 years on the tank and 2 years comprehensive coverage.
Always check the exact model's current warranty terms before purchasing.
Smart Storage Water Heaters
For users who want more than conventional temperature control, Aquator IoT adds connected functionality to a storage geyser.
The current model includes a smart LED temperature display and touch control, along with Smart Mode and Eco Mode. It also carries a 5-Star rating, up to 8-bar pressure compatibility and 7-year tank, 4-year heating-element and 2-year product warranty.
Choose a smart geyser when remote or connected control is genuinely useful in your routine. For straightforward hot-water needs, a conventional storage model may be all you need.
Storage Water Heaters with Multi-Level Safety
Safety features vary by model, but some Orient Electric storage geysers combine several layers of protection.
-
Aquator Neo includes a 5-in-1 safety system comprising a precision capillary thermostat, automatic thermal cut-off, multifunction safety valve, IPX4-rated splash-resistant body and fire-retardant outer shell.
-
Aquanova Neo also includes multi-level protection with a high-precision thermostat, thermal cut-off, multifunction safety valve and IPX4-rated body.
The safety features of the selected model should be checked before installation rather than applying one safety specification across the entire range.
What Happens to a Storage Geyser During a Power Cut?
A storage water heater does not continue heating when the electricity supply is off. However, because it stores water that has already been heated, some hot water may remain available from the tank until it is used or loses heat.
How long that hot water remains useful depends on the amount stored, insulation, ambient conditions and how much water is drawn from the tank.
This is one of the practical differences between a storage water heater and an instant model, which heats water as it flows. For on-demand heating, explore Orient Electric's Instant Water Heaters category.
Storage vs Instant Water Heater
| Storage water heater |
Instant water heater |
| Stores heated water in a tank |
Heats water as it flows |
| Available in larger tank capacities |
Generally more compact |
| Useful when stored hot water is needed |
Useful when on-demand heating is preferred |
| Capacity is a major buying decision |
Wattage and flow are important considerations |
| Vertical and horizontal storage formats available |
Compact point-of-use formats available |
For households with regular bathroom demand and a need for stored hot water, a storage geyser can be a natural fit. When space is tight or on-demand heating is more suitable, compare an instant model instead.
