The Difference Between Water Heaters (Electric – Instant – Solar)

A water heater is one of the essential home appliances, especially with the cooler months approaching in Saudi Arabia. But with so many types — electric, instant, and solar heaters — choosing the right one can be confusing.


In this article from Sawab, we break down the differences and help you pick the best option for your home.


🔌 Electric Water Heater


The electric water heater stores and heats water inside a built-in tank.

Pros:

  • Keeps water hot for long periods.
  • Ideal for large families.
  • Available in various tank sizes.

Cons:

  • Consumes more electricity.
  • Takes time to heat up the full tank.


Best for: Homes that need large amounts of hot water regularly.


⚡ Instant Water Heater


The instant heater heats water immediately as it flows through the unit, without storage.

Pros:

  • Energy-efficient — works only when needed.
  • Compact and space-saving.
  • Provides continuous hot water.


Cons:

  • Requires strong water pressure.
  • Not ideal for high-demand use.


Best for: Small families or quick use in kitchens and bathrooms.


☀️ Solar Water Heater


The solar heater uses solar panels to heat water — an eco-friendly and cost-effective solution.

Pros:

  • Reduces electricity bills.
  • Environmentally friendly.
  • Works great in sunny regions across Saudi Arabia.


Cons:

  • Requires installation space.
  • Less efficient on cloudy or cold days.
