Hot Water Systems

8 March, 2024

A reliable hot water system is essential for any home, providing comfort and convenience for daily tasks like showering, washing dishes, and doing laundry. With several types of hot water systems available, each with its own advantages and disadvantages, it can be challenging to determine which one is best suited for your home and lifestyle. In this blog post, the experts at Panther Plumbing Group break down the different types of hot water systems to help you make an informed decision.

1. Electric Storage Hot Water Systems

Electric storage hot water systems are a popular choice for many households. These systems use electricity to heat water, which is then stored in an insulated tank for use when needed.


  • Relatively inexpensive to purchase and install
  • Low maintenance requirements
  • Suitable for a wide range of water conditions


  • Higher operating costs compared to other systems
  • Limited hot water supply based on tank size
  • Slower recovery time when the tank is depleted

2. Gas Storage Hot Water Systems

Gas storage hot water systems work similarly to electric storage systems, but they use natural gas or LPG to heat the water instead of electricity.


  • Lower operating costs compared to electric systems
  • Faster recovery time when the tank is depleted
  • Can still function during power outages


  • Higher initial purchase and installation costs
  • Requires a gas connection or LPG tank
  • Slightly higher maintenance requirements

3. Continuous Flow (Instantaneous) Hot Water Systems

Continuous flow or instantaneous hot water systems heat water on demand, providing an endless supply of hot water without the need for a storage tank.


  • Endless supply of hot water
  • Compact size, saving space
  • Energy-efficient, as water is only heated when needed


  • Higher initial purchase and installation costs
  • May struggle to meet high hot water demands simultaneously
  • Requires a minimum water flow rate to activate heating

4. Heat Pump Hot Water Systems

Heat pump hot water systems use electricity to move heat from the air into the water, rather than generating heat directly. This makes them highly energy-efficient.


  • Highly energy-efficient, reducing operating costs
  • Environmentally friendly, with lower greenhouse gas emissions
  • Can be connected to off-peak electricity for further savings


  • Higher initial purchase and installation costs
  • Requires installation in a well-ventilated area
  • Less efficient in cold climates or during cold weather

5. Solar Hot Water Systems

Solar hot water systems use energy from the sun to heat water, making them an eco-friendly and cost-effective choice in the long run.


  • Significantly reduces energy costs
  • Environmentally friendly, with minimal greenhouse gas emissions
  • Government rebates and incentives may be available


  • High initial purchase and installation costs
  • Requires suitable roof space and orientation for optimal performance
  • May require a backup energy source for cloudy days or high demand periods

Choosing the Right Hot Water System for Your Home

When selecting a hot water system for your home, consider the following factors:

  • Household Size: Consider the number of people in your household and their hot water usage habits to determine the appropriate system size and capacity.
  • Available Energy Sources: Evaluate the energy sources available in your home, such as electricity, gas, or solar, and their associated costs.
  • Space and Location: Assess the available space for the hot water system and any installation requirements, such as ventilation or roof space for solar panels.
  • Budget: Compare the initial purchase and installation costs, as well as the ongoing operating and maintenance costs of each system type.
  • Environmental Impact: Consider the environmental impact of each system type and prioritise eco-friendly options if sustainability is a key concern.
