What is the lifespan of a hot water system?

There isn’t a one-size-fits-all answer to the average lifespan of a hot water system, every system is different, and it depends on the water quality, and regularity of maintenance. However, a gas storage hot water systemelectric storage hot water system or instant electric hot water system will last between 10-15 years. On the other hand, an instant gas hot water system or solar hot water system can last up to 20 years. By regularly maintaining a hot water system, including flushing the tank, checking the pressure relief valve and replacing the anode rod, you can significantly increase the lifespan of a hot water system.

How to determine the appropriate size hot water system for your needs?

Every household is different, with differing hot water needs and usage patterns, so naturally, the size of your hot water system will be dependent on these circumstances. Usually, when purchasing a hot water system, you will need to take into consideration the number of occupants in your home, how many bathrooms you have and how many appliances you have that regularly use hot water. With this information, a professional plumber can help you to calculate the right size hot water system for your needs.

Signs that it's time to replace your hot water system

Has your trusty hot water system seen better days? If you are worried about your hot water heater or fear your hot water system lifespan is coming to an end, there are a few signs that you may be right.If you notice any of the below signs, it may be time to replace your hot water system:

  • Age: If your hot water system is more than 10-15 years old, it’s likely coming to the end of its healthy lifespan, and the future could be full of repairs and problems if you don’t replace it soon.
  • Inefficiency: If your hot water system is not providing consistently hot water or taking a long time to heat up, it’s possible you are dealing with a malfunctioning thermostat, heating element, or sediment buildup. In any of these cases, it’s best to call in the professionals to determine if you need maintenance or a replacement.
  • Leaks: If you have been noticing water pooling around your hot water system, then you are likely experiencing a leaking hot water system. This is important to get on top of as it can cause both water damage and a hefty utility bill.
  • Strange noises: If you hear rumbling, popping, or banging noises coming from your hot water system, chances are something is not quite right, and it may indicate that your heating system has sediment buildup or a faulty heating element.

Gas vs solar vs electric hot water systems

There are advantages and disadvantages to gas, solar, and electric hot water systems. Which option is best for you will depend on where you live, the climate, energy costs and personal preferences. For example, gas hot water systems are a popular option as they provide fast heating and low operating costs.

However, they require a gas connection and regular maintenance. Solar hot water systems, on the other hand, are a planet-friendly and cost-effective solution, but only in sunny areas; they will be less efficient in cloudy or rainy climates. Electric hot water systems are both easy to install and maintain, but they can sometimes be expensive to run and may not be able to provide enough hot water for large families or businesses.
