That is going to largely depend on how many people reside in your house, your average water use, and when you're using it. If you get a hot water system that's too small, you'll continually run out of hot water. If you get one that's too large, it will cost you more to run it. It's important that you choose the right hot water system for your household needs. Sunpak can help you identify the right system for your home.

There are five main criteria:

• Types:
  • There are three different types of fuel options. Gas, electric or solar. You'll need to choose one of these first.
• Kinds of hot water systems:
  • Storage systems - Storage hot water systems use a tank to store hot water
  • Continuous systems - continuous flow system only heats water when needed. Water is heated as it passes through heating equipment.
• Size of hot water systems:  
  • Electric storage

• • Gas continuous flow 

• Cost and Maintenance:
  • Below you'll find hot water system prices. These show the different systems available. You'll see both minimum and maximum prices. These are average prices and may vary from job to job.

• Energy Efficiency:
  • The most energy-efficient hot water system is a heat pump system.

Gas hot water systems

How it works

A gas hot water system has a gas burner, which continuously heats and maintains the water in your tank. A continuous flow system or tankless system uses a burner that only ignites when the water is needed.

Pros

Hot water on demand when using the continuous flow systems. They do not use any energy when not in use. Good for a hot water outlet that has only occasional use.

Cons

A gas hot water system is only a viable option if you're connected to mains gas. If you use external gas bottles, it can be a lot more expensive. You can easily run out of hot water too.

Electric hot water systems

How it works

An electric hot water system uses an element to heat the water. It's stored in an insulated tank, ready for use.

Pros

Electric hot water systems have low up-front costs, and are reliable. Some electric hot water systems can also be set up to heat during off-peak periods to help with your energy bill costs.

Cons

Generally expensive in the long-term and higher greenhouse gas emissions if the system is not powered by a renewable energy source.

Heat pumps

How it works

A heat pump has a fan installed that draws warm air into the system. This is transferred into the water storage tank. Think of it as a reverse fridge. Instead of pushing hot air out to keep your fridge cook, it pulls in hot air to heat your system up.

Pros

A heat pump is one of the most energy-efficient hot water systems available. While they do require electricity to run, they are up to 75% more efficient than most electric hot water systems.

Cons

Generally, a heat pump is best suited in a warm environment. Some heat pumps can come with boosters, if the climate is cold, there is little benefit in spending the additional money on installing a heat pump.

Pool heaters

How it works

A pool heater heat pump has a fan installed that draws warm air into the system. This is transferred into the water storage tank that then heats your pool or spa. Think of it as a reverse fridge. Instead of pushing hot air out to keep your fridge cook, it pulls in hot air to heat your pool or spa up.

Pros

A heat pump is one of the most energy-efficient pool heaters available. While they do require electricity to run, they are about three times more efficient than most electric pool heaters.

Cons

Generally, a pool heat pump is best suited in a warm environment. Some pool heat pumps can come with boosters, if the climate is cold, there is little benefit in spending the additional money on installing a pool heat pump.

Installing a heat pump for residential homes costs from $2,800 to $3,500. We currently have a special offer for the award-winning EvoHeat Evo270 Heat Pump – click ​here​ for more information.

For commercial heat pumps, please contact us for a quote.

To ensure optimal performance and sufficient access to warm air, heat pumps should be installed outside your home in a well-ventilated area.

You shouldn't notice too much noise from your heat pump as it will be installed outside your home.

The ​EVO 270​ has a noise level rating of 49dB (A), which sounds similar to a split system air conditioner.
