What To Do About A Struggling Hot Water System

Category: Save Water

There’s nothing quite like enjoying hot showers during the cooler months so what are you to do when your hot water system can’t keep up? Can you remember the last time you serviced or replaced your hot water system? Hot water, repairs and upgrades should be made as soon as you detect an issue otherwise what seems to be a small issue at first can turn out to be a much costlier and inconvenient problem. Today we’re sharing the options you have available with Laser Plumbing Canberra Central.

What’s wrong with my hot water system?

Years and years of daily usage takes its toll and like any other household appliance, hot water units don’t last forever. If you’re noticing a decrease in performance, your hot water unit may need maintenance, repair, or perhaps to be replaced.

One of the most common hot water complaints we hear is when the existing system isn’t large enough (or the right type of system) to handle the amount of use it gets. You know this is the case if you live in a household where the last one to take a shower has to experience the hot water suddenly stopping! This isn’t so much an issue with the system itself, more with the suitability of the system for your family.

If there are leaks it could be a sign that parts of your hot water system are corroding. You should check the age of the hot water system and look for the manufacturer’s badge. The source of the leak may be at the top or the bottom of the cylinder although be careful in locating the source of the leak as direct connection between water and electricity is obviously very dangerous. If you are unsure of what the issue is- don’t DIY but call a professional plumber instead within 24 hours of detecting a problem.

What are my options?

There are three main solutions if you are faced with a hot water system that has broken down or isn’t meeting your needs anymore: repair, replacement or upgrade.


While some people will put up with cold showers and weak water pressure because they don’t want to to replace the hot water system, the good news is that repairs maybe all that is required and you don’t need to invest in a brand new system.

Repairs may be warranted if water flowing excessively from the temperature pressure relief (TPR) valve, the hot water cylinder is leaking or no hot water is flowing from the water tap. Like any home appliance, hot water systems need regular maintenance to avoid costly repairs. Without routine servicing, you can be out of pocket for avoidable pipe leaks, hot water tank leaks and other hot water system problems.

Things as simple as a colony of ants moving in at the base of the system can cause it to stop working, as can one too many hits with the whipper snipper so it’s worth getting a professional in to take a look at it - you might be pleasantly surprised at how cost effective repairs can be!


If the repairs are too costly and damage is beyond repair, replacing the hot water system may be a better option. A hot water system specialist can offer a fast way to changeover your leaking or faulty hot water system with something similar or propose a more efficient system that is available through modern technology. An expert technician can walk through with you your hot water system options including the differences between an electric storage system versus its gas and solar equivalents as well as the benefits of a continuous flow system if you are looking to cut back on energy bills.

At Laser we have an emergency hot water replacement service with stock of the most popular hot water systems available so you can have your hot water system back up and running as quickly as possible.


Hot water accounts for around 25% of the average home energy costs, so it’s definitely an area that you can make big savings if you upgrade to a better quality system or purchase a system that is not larger than you actually need. To determine size of the hot water system required, some questions worth asking include:

  • Do members of your household take showers at the same time of day?
  • Is the washing machine run using hot or warm water while people are showering?
  • Is your dishwasher connected to the cold or hot water? If hot, do you run the dishwasher while hot water is being used elsewhere in your home?
  • Do you live in a cold climate with cold incoming water?

At Laser Plumbing, we can help you figure out your family’s peak usage period and when you use additional water so you can save money and energy. As there are plenty of options out there on the market, our experts can help you with making the best decision by offering you a system to match your needs.
