If you’re considering installing a new hot water system in your home in NSW, you’ll need to be aware of the state regulations when having it fitted. The majority of these regulations have been introduced by the state government to improve your home’s energy and water efficiency while keeping your greenhouse emissions as low as possible. If you’re unsure of what these regulations are, we can help. Take a look here at the most common hot water system regulations in NSW.
Energy Efficiency or Energy Star ratings
Energy efficiency or energy star ratings are used to compare electric hot water units of the same type so that you can make an informed decision about your new hot water system’s energy efficiency. This is an efficiency rating system that is regulated by the Government’s MEPS (Minimal Energy Performance Standards) scheme. The more stars that your hot water system has, the more energy-efficient it is going to be.
Temperature and installation
There are several temperature and installation regulations that you must be aware of:
- The minimum temperature of a water storage tank must be greater than 60 degrees to avoid bacterial growth in the tank. This helps to ensure that the environment is too hot for Legionnaires Disease bacteria to grow.
- Taps must be restricted to a maximum outlet temperature of 50 degrees to avoid scalding. A tempering valve can help ensure that your hot water is at the correct temperature – this valve is generally part of the piping of your system.
Watermark Certification Scheme
The Watermark Certification Scheme provides peace of mind that the product in question is up to the quality and safety standards outlined by the Australian Building Codes Board (ABCB). Note: it’s legal to buy or install non-WaterMark certified plumbing and drainage products in Australia. Some consequences of not using WaterMark certified products include voided insurance, the costs of replacing materials and building damage in the case of product failure.
It is vital that there is sufficient ventilation for your hot water system to operate and for any gases to escape. If you are building a new home, it is recommended that licensed gas fitters or hot water system experts liaise with builders to determine the best position for your hot water system.
Brackets and fixings
Brackets and fixings must be sufficient to hold your hot water system when it is full and the weight has increased. If there is soil present under your system, it must be tightly compacted to prevent soil erosion and to minimise any chance of bracket or fixing problems during installation.
