  • A four-person household is estimated to need a 125L-160L tank for a continuous system or 250-315L for off-peak.
  • If there is an emergency, electric instantaneous water heaters are available.

  • Installation is between two to three hours if the replacement is of the same system.
  • A four-person household needs 135-170L, and an instantaneous system is available.

  • Solar storage tanks cannot always be installed in your preferred location; you will need a large collection area which aesthetically is not always desirable.
  • In comparison to other hot water systems, solar can be an expensive option and time costly to install. The plumber will be required to inspect your home to inform you whether solar is viable. Solar long-term will pay for itself due to the low-running costs.

Heat Pump

  • A heat pump extracts heat from the air and utilises it to heat the water system. Units are typically joint (tank and compressor), but can be separated too.
  • Installation tends to take an estimated two to three hours for a direct replacement or a similar model.
  • Heat pumps are required to be installed in a ventilated area which is typically outdoors.
  • The compressor on the unit can be loud; there is not always suited for apartment-style living.
  • You will require a 270-315L tank for a four-person household.
  • They work best in warm climates, but there are models available to function optimally in cold temperatures too. Systems have a booster element for cold days or high water usage.

Storage tank

  • Electric, gas, solar and heat pump hot water systems mostly use a tank.
  • Tanks are insulated, however some heat loss, so it is best to install them in a spot which has high sun exposure.
  • Tanks can wear over time and maintenance every couple of years can hinder this. Typically they have five to ten-year warranties.

Continuous flow

  2. Most of the continuous flow models utilise gas, but there are electric models too.
  3. They are often more cost-effective to run because there are no heat losses compared to water in a tank.
  4. Electric continuous flow models use full electricity when they are being used; therefore, costs associated with this model tend to be higher.
  5. Something important to note is sometimes continuous flow heaters do not produce adequate heat if water pressure is too low. If you have a continuous flow model and your shower water is cold, this may be something to keep in mind. The trigger point may need to be assessed to work out if a continuous flow model is best for you.
  6. To make sure you select the right top hot water heating system for your property you’ll need to speak to an expert to know if you require an electric or gas model.
