Heating Systems with Storage

These traditional models are the most well-known kind of water heaters found that are used in most homes. They are equipped with tanks that store water and run on natural gas, electricity propane, or fuel oil.

Benefits from Storage Water Heaters

  • They're available in a vast selection size options, and tank sizes typically in the range of 20 to 80 gallons
  • They're usually inexpensive to buy and to install.

The disadvantages of Storage Water Heaters

  • Tank sizes have grown and these systems are more likely to need larger amounts of space.
  • They provide a small amount of hot water for prolonged durations.
  • They could be wasting up to 15% of their energy by losing heat through radiation.
  • They generally have a lifespan of between 10 and 15 years.


Tankless hot water heaters

Also known as demand-type or instantaneous water heaters, tankless heaters don't have storage tanks. They utilise gas burners or electric elements to warm water when the hot water faucet is activated.

Benefits of Tankless Water Heaters

  • They use 20 to 30 percent less energy than models for storage tanks.
  • They require minimal area without increasing the cost of installation.
  • They can be put up on the wall.
  • They generate a minimal amount of waste energy from standby.
  • They can provide an almost inexhaustible source in hot water.
  • They live an average duration of 20 years or more.
  • Their average rating is in the range of 0.75.

The disadvantages of tankless water heaters

  • The rate of flow of hot water is limited by the dimensions of the device.
  • Tankless systems are typically more expensive and can be more difficult and costly to set up.

Electric Hot Water Systems

These are designed to heat water with an element powered by electricity that sits at the bottom of the tank. The internal element is twisted around pipes to quickly heat the water in the tank.

Solar Hot Water Systems

Hot water solar heaters make use of the storage concept as they utilise the heat by the sun that is collected by solar panels at the top of your property.
