AO Smith EWS Plus is a compact 3-litre instant water heater designed for both kitchen and bathroom use. Its 3 kW Incoloy heating element helps heat water quickly, making it convenient when there is little time to wait. Blue Diamond glass tank technology provides additional protection against corrosion and supports long-term durability. The five-year tank warranty adds further reassurance for buyers. Its small size makes the appliance suitable for homes where installation space is limited. The geyser is mainly intended for short and regular hot-water requirements rather than heavy family usage.

Pros:

  • It fits comfortably into smaller bathrooms and kitchens where installing a large geyser may not be practical.
  • The Incoloy heating element helps warm water quickly for short showers and everyday household tasks.
  • This Blue Diamond glass tank provides additional protection against corrosion and regular water exposure.
  • A five-year tank warranty gives useful peace of mind for long-term household use.
  • It can be installed in either a kitchen or bathroom depending on where hot water is needed.
  • The compact format is convenient for users who generally consume small quantities of hot water.

Cons:

  • It has only 3 litres of storage, which may not be enough for several family members.
  • The available hot water can run out quickly during longer bathing sessions.
  • This compact capacity may need to be heated again during consecutive use.
  • A 3 kW heating element needs proper wiring and a suitable electrical connection. 
  • Larger families may find a higher-capacity storage heater more comfortable for daily routines.
  • Regular maintenance should still be considered after the warranty coverage comes to an end.

Best For:

This is best for bachelors, couples and small households where hot water is required in smaller quantities. The compact body is convenient for kitchens, guest bathrooms and smaller living spaces. Users who value quick heating and better protection against corrosion may find the Blue Diamond glass tank useful for regular use. A five-year tank warranty also adds some reassurance for long-term ownership. Short showers, washing utensils and everyday cleaning are the kind of tasks where this model makes the most sense. Families with heavy hot-water consumption should look at larger storage options.
