Hot Water System Repair & Maintenance

Hot water systems are an essential part of any home in Brisbane, providing a consistent hot water supply for bathing, cooking, and cleaning. However, it can also be a source of energy waste if not properly maintained. In particular, leaks in the unit can lead to a loss of hot water and an increase in energy bills. It is therefore essential to repair any leaks in the hot water system as soon as you notice them. 

Projection Plumbing’s hot water system repairs will provide years of trouble-free operation.


Types of Hot Water Systems


There are three primary types of hot water systems:

Tankless systems
These units heat water on demand, meaning there is no need to store hot water in a tank.

Solar systems
These systems rely on solar panels to absorb the sun’s energy and transfer it to a circulating pump. The heater in the pump is responsible for heating the water whenever you need it.

Tank systems
These units store hot water in an insulated tank and use a heat exchanger to heat the water on demand.

6 Reasons Why Your Hot Water May Not Be Working

Leaking tank 

If you suspect your hot water tank is leaking, have an inspection done by a professional as soon as possible. A qualified technician from Projection Plumbing will be able to determine the source of the leak and make the necessary repairs. 

Gas leak 

A gas leak may stop your hot water system from working correctly. If you smell, see a broken gas pipe, or hear a hissing sound, contact Projection Plumbing and immediately evacuate the area.

Failing gas valve 

The gas valve is responsible for opening and closing the gas flow to the burner. When it fails, it can cause the burner not to ignite.

Thermostat not working 

The thermostat controls the temperature of the water in the system, and if it’s not working properly, the water may not get hot enough. 

Malfunctioning of electric water heater 

If your hot water system isn’t working, there’s a good chance it’s due to the electric water heater. A tripped circuit breaker or a blown fuse is one of the most common issues. A technician from Projection Plumbing will find the problem and fix it quickly.

Tank size 

As homes are built to be more energy-efficient, the demand for hot water has increased, but the size of the tanks has stayed the same. This can lead to a drop in water pressure and an inconsistent hot water supply.

Josh has been out to sort out a few plumbing problems I have experienced since buying my house. With next to no knowledge about plumbing myself he is more than happy to send the guys out to have a look at the most miniscule of problems (like an empty gas bottle lol), nothing is a hassle! They are always available to come out very quickly, super friendly, and prompt and efficient. I would 100% recommend Josh and the team at Projection Plumbing!

Josh & Jason were fabulous & did an amazing job. I have had to put up with cold showers for I don’t know when! I’ve been avoiding dealing with multiple repairs & tradies. What a pleasure dealing with Projection Plumbing. They were very professional, on time, price was good & they cleaned up afterwards. The job turned out to be more challenging then first thought but they were determined to fix my problem & I’m very grateful. I wouldn’t use anyone else.

Josh was amazing. He came exactly when he said he would and messaged updates when he said he would. He understood the problem and tried some cheaper options for us before he had to remove our toilet completely. Josh was extremely friendly and talked me through every step as he went. He left our toilet in perfect working order and cleaned up after the work. I will definitely use Projection Plumbing again after this experience. Thanks Josh for your outstanding service

We were looking for a plumber to use as our regular and Josh was highly recommended by one of our customers. We are a restaurant and had a hot water heater meltdown and of course desperate to get it fixed asap. Josh came to the rescue and arrived on time the next day and installed a new system and did a fantastic job at a realistic price. We couldn’t be happier with his service. He will certainly now be our regular plumber. I’ve already recommended him to my brother in law who had the same problem and he also had the best of service from Josh.
