How Do Hot Water Systems Work?

Hot water systems are essential to our homes, but they can also be difficult to understand, especially with so many different types. If you’re in need of a new hot water system and want to better understand the different types and how they work, keep reading. 

What is a hot water system?

Hot water is a hugely important aspect of our everyday lives and we simply couldn’t live without it. Without a hot water system, we wouldn’t have access to the hot water that we use every day for things like showers, dishwashing, and so much more. There are many different types of hot water systems you can choose from that our expert Sydney plumbers can install for you. 

What are the types of hot water systems?

There are many types of hot water systems that are commonly used in Sydney, but the main four are; 


  • Electric hot water systems
  • Instant gas hot water systems
  • Gas storage hot water systems
  • Heat pump hot water systems

How do they each work?

All of these different types of systems have different ways in which they work. 

Electric hot water systems

There are two types of electric hot water systems that you may choose between, continuous flow or storage. Both of these work fairly similar where cold water is collected in the tank and is then heated up. The main difference between the two types is that for a storage system, all of the water is heated up and stored before being sent out to the right place when a tap is turned on. However, in a continuous flow system, the water is heated only as needed. 

Instant gas hot water systems

An instant gas water heater works similar to a continuous-flow electric hot water system where the water is heated whenever it’s needed. However, this water heater works on a gas system instead of an electrical system. Instant gas hot water systems come in both LPG and natural gas models.

Gas storage hot water systems

Gas storage hot water systems work by heating a burner under the tank. As the burner heats the water in the tank, hot water slowly rises to the top and whenever a hot tap is turned on, the water flows out to where it’s needed. 

Heat pump hot water system

Heat pump hot water systems work by transferring the heat from the air outside and using it to heat the water inside the tank. Modern heat pump systems are even usable in cooler climates making them great for anyone.
