Frequently Asked Questions about Electric Hot Water Systems

There is no definitive answer when it comes to the best. In reality, the best electric hot water system for your home comes down to a number of factors. So when you are thinking about hot water, consider:

  • How many people are using it
  • Whether multiple people use hot water at the same time
  • What household appliances need direct hot water
  • How much water your household uses
  • The local climate, i.e. is solar possible
  • What budget you are working with

Mr Emergency can assist in selecting an appropriate electric hot water system for your home.

Unlike gas hot water systems, electric water heaters do not require star ratings for energy efficiency. Therefore, you will find choosing between brands like Dux, Rinnai or Rheem is based on personal choice. There is no easy way to compare efficiency.

If you are after efficiency and a reduced environmental impact, look to heat pump water heaters or solar power. Both units rely on renewable energy for high quality water heating.

No, electric instantaneous water heaters are not expensive to run, especially compared to storage tanks. There are considerable savings as water is not being heated 24/7.

Instead, electricity is only required when you actually need the hot water. Although electric instant hot water systems are less common, they are suited to small homes without a gas supply.

You can expect the average hot water unit to last between 8-12 years at least. A well-maintained system, and in particular a continuous flow system, can last upwards of 15-20 years. Local conditions, maintenance and usage patterns will impact longevity.
