Hot Water Systems

Hot water systems use a variety of heating methods to provide consistent hot water in your home, including gas, electric, solar or heat pump units. We also supply a range of water controllers, which enable you to select the exact temperature of your hot water at the touch of a button.

At Appliances Online, we offer gas and electric hot water systems from leading brands such as Rheem and Rinnai. With our large range of top-quality hot water heaters, you're certain to find a system that suits your needs.

Be sure to check what heating method you use before you purchase, to ensure you’re buying the right product for your home.

Hot Water System Types

A hot water system is available as either an instantaneous or storage tank unit.

  • Instant systems (continuous-flow) heat water instantly and as it’s required. Thanks to their instantaneous nature, they’re generally cheaper to run and more efficient than storage units, which can lose heat over time.

    The most important aspect in choosing a continuous-flow system is the Flow Rate. The more water outlets you have in your home, the higher your flow rate should be.

  • Storage tank systems, on the other hand, store a certain amount of heated water that is used throughout the day. Their biggest advantage is making use of cheaper off-peak energy tariffs to fill your water tank. (Note that off-peak electricity isn't available to every home).

Electric Hot Water Systems

  • Electric systems are often cheaper to buy and install than gas systems, but are more expensive to run due to electricity prices.
  • Electric systems can be installed indoors or outdoors.
  • They're available in a range of sizes depending on the size of your household.

Gas Hot Water Systems

  • Gas hot water systems are found in either natural gas or LPG.
  • Gas systems are cheaper to run than electric ones, though their initial cost is generally more expensive.
  • Due to their need for venting, gas systems are usually outdoor units, but in some cases can be installed indoors with a flue.

Hot Water Heat Pumps

  • Hot water heat pumps work by using electricity to move heat from one place to another instead of generating heat directly
  • Hot water heat pumps are more energy efficient than conventional electric water heaters.
  • They're available in a range of sizes depending on the size of your household.
