23 / 06 / 2023

To help you make a smart choice and save money for your first hot water system, here are some useful tips: 

  • Assess your hot water needs. Determine the amount of hot water your household requires on a daily basis. Consider the number of occupants, frequency of hot water usage and peak demand periods. This information will help you choose a system with just the right capacity. 
  • Understand the different types of hot water systems. Familiarise yourself with the various types available, including storage tank systems, tankless (instantaneous) systems, heat pump systems and solar-powered systems. Each has its advantages and considerations in terms of cost, energy efficiency and installation requirements.

  • Think about energy efficiency. Opt for a hot water system that is energy-efficient to reduce your long-term operational costs. Look for systems with high energy star ratings or those that meet energy efficiency standards. Consider options like heat pump systems or solar-powered systems, which can provide significant energy savings over time. 
  • Consider fuel type. Determine the most suitable fuel type for your hot water system. Common options include electricity, gas (natural gas or LPG) or solar energy. Assess the availability, cost and environmental impact of each fuel type in your area. 
  • Compare costs. Consider both the initial purchase price and the ongoing operational costs. While some systems may have higher upfront costs, they may offer better energy efficiency and lower operational expenses over time. Compare the purchase price, installation costs, maintenance requirements and expected lifespan of different systems. 
  • Check space availability. Evaluate the space available for installing the hot water system. Some systems, like storage tank systems, require sufficient space for the tank, while others, like tankless systems, have smaller footprints. Ensure that the chosen system can be installed comfortably in your available space. 
  • Seek professional advice. Consult with a qualified plumber or hot water system specialist who can assess your specific needs and provide expert advice. They can recommend suitable options based on your requirements, budget, and the unique characteristics of your property. 
  • Read about government rebates and incentives. Check if there are any government rebates or incentives available for installing energy-efficient or environmentally friendly hot water systems (especially for solar water heaters). These incentives can help offset the initial costs and provide additional savings. 
  • Check maintenance and warranties. Consider the maintenance requirements and warranty coverage of the hot water system. Regular maintenance can prolong the system’s lifespan and optimize its performance, while a comprehensive warranty can protect you against unexpected repairs or replacements. 

By carefully evaluating your needs, considering energy efficiency, comparing costs, and seeking professional advice, you can choose a suitable hot water system that meets your requirements while saving money in the long run.
