Examples of recent hot water system repairs.
SOLAR HOT WATER SYSTEM REPAIR
We were recently contacted by a customer whose Thermann solar hot water system had begun leaking. The system featured rooftop solar collectors and a ground-mounted storage tank, which had split and was pouring water from the side of the house. Fortunately, the tank was outdoors, preventing water damage to the home. Over the phone, our hot water specialist John guided the customer through shutting off the water supply to stop further flooding.
On inspection, it was confirmed the hot water tank was beyond repair, but the solar components, including sensors and the pump, were still working efficiently. After discussing the customer’s needs and preferences, John recommended a Thermann Solar Electric Tank 250L (TH250GLG). This model is similar in capacity to their previous system. The customer was satisfied with this solution, and the new tank was supplied and installed on the spot, restoring their hot water service within hours.
As part of the job, we safely disconnected and removed the old tank, reused the existing tempering valve and connections, and recommissioned the system. The site was left clean and tidy, and the old tank was recycled responsibly. Thermann Hot Water is a trusted Australian-owned brand known for its reliable gas, electric, solar and heat pump hot water systems, offering excellent value and performance for Sydney homes.
GAS HOT WATER SYSTEM REPAIR
This customer’s gas hot water system had stopped working entirely, leaving them without hot water. Understandably frustrated, they needed help fast and we were happy to assist.
Once on-site, Steve quickly identified the problem and completed the necessary repairs on the spot. In our fully stocked service truck we had the necessary parts so could get them back up and running.
While we were there, we gave the system a full service to ensure it was operating safely and efficiently. Regular maintenance is important to prolong the life of your gas hot water heater, improve performance, and avoid unexpected breakdowns. By the time we left, the customer had hot water again, along with peace of mind that their system had been properly checked and serviced.
ELECTRIC HOT WATER SYSTEM REPAIR
This customer called us when they noticed they had gradually losing hot water the day before and, when they woke up, had no hot water at all. The cause? A not so surprising one – ants had infested the water heater’s electrical components, stopping it from working correctly.
Once onsite, we found a large number of ants had nested inside the electric water heater, particularly around the thermostat and wiring. This caused short circuits, corrosion, and complete failure of the system. This is not uncommon because ants are drawn to the warmth of electrical equipment, and in this case, they made themselves at home.
We carefully cleaned out the electrical compartment, removed all ant debris, and replaced the damaged thermostat. We also serviced the unit, flushing the tank, testing the heating elements, checking the anode rod, and ensuring all components were safe and working correctly. Once complete, the system was fully operational again. We recommended the customer contact pest control and seal any access points around the unit to avoid future infestations.
If your hot water system isn’t performing as it should, or you’re due for a service, give us a call — we’re here to help and are ready for anything.
SOLAR HOT WATER SYSTEM REPLACEMENT
We recently helped a customer upgrade their ageing solar hot water system with a new Rheem Solar Highline. The existing system was no longer performing efficiently, and a replacement was the most cost-effective option. To minimise disruption, we installed the new system in the same rooftop position, keeping the original layout and plumbing in place.
Solar tanks and collectors are heavy and bulky, so safe and precise installation is essential. Using our MightyLift lifting equipment, we were able to place the new system on the roof quickly and safely without the risks and delays that come with manual handling. This allowed the installation to be completed efficiently, with minimal disruption to the homeowner.
The new Rheem Solar system will provide improved performance and long-term energy savings. With the job completed and the system up and running, the customer now has reliable solar hot water again.
At Cheapa Hot Water, we use the right tools and industry experience to make every job smooth, safe and stress-free.
EMERGENCY HOT WATER SYSTEM REPAIR
We were recently attended a customer’s home for an emergency repair after their old gas hot water system had caught fire. They managed to extinguish the flames before we arrived, but were understandably concerned it might happen again. One of our licensed hot water specialists was onsite within the hour to assess the situation and make it safe.
While fires like this are rare, it’s a strong reminder of why regular hot water system servicing is essential. Over time, wear and tear can lead to dangerous faults. A professional service every 5 years can help identify potential problems early, extend the life of your system, and ensure it continues operating safely. Our service includes inspecting and testing all key components, replacing worn parts where needed, and checking that the system meets all safety standards.
In this case, the hot water system was beyond repair and needed to be replaced. We safely disconnected and removed the damaged unit and installed a new Rheem Stellar 330 gas hot water heater. This premium system features a 130L storage tank, fast hot water recovery (200L/hr), and a 5-star energy efficiency rating. The household was back enjoying reliable hot water just a few hours later — with the added peace of mind that their new system includes the latest safety and efficiency features.
HEAT PUMP REPAIR
We attended a customer’s home where their old Rheem heat pump had begun leaking. On inspection, it was clear the unit was beyond repair. The customer had been happy with its performance and energy efficiency, so they wanted a similar replacement.
After discussing a few options, they chose the Rheem Ambiheat HDc270 (Model 551270), The Ambiheat is a next-generation 270L heat pump designed for maximum efficiency and reliability. Built in Australia and ideal for a range of climates, the Ambiheat uses heat from the surrounding air (not sunlight) to heat water, making it a great choice for homes where solar isn’t suitable. It also features advanced microchannel technology for faster heating, quiet operation, and smart controls for convenience.
Older hot water systems can develop leaks and efficiency issues over time. Replacing them with a high-performance unit like the Rheem Ambiheat is a smart long-term investment — reducing energy bills, preventing breakdowns, and delivering consistent hot water. If your heat pump is leaking or underperforming, contact our experienced team today for expert advice and fast service across Sydney.
6 common hot water system problems.
We’ve been repairing hot water systems across Sydney for over 30+ years and have seen just about every issue a water heater can throw at you. Below are the most common problems we encounter and how we fix them.
No hot water
- A complete loss of hot water usually points to a faulty thermostat or heating element.
- For electric systems, this often involves a quick onsite replacement of the heating element or thermostat — an affordable and fast fix.
- For gas systems, a common cause is a pilot light that has gone out. Try relighting it using the manufacturer’s instructions. If it won’t stay lit, the thermocouple may be faulty.
- Don’t feel confident handling it? Call us for advice — we can usually diagnose the issue quickly and safely.
Running out of hot water
- Increased household demand (e.g. more residents or growing teens) often means your tank is no longer large enough. Upgrading to a larger, more energy-efficient system can help — many modern units use less energy than older models.
If demand hasn’t changed, it could be: - A thermostat set too low (standard is around 49°C).
- A broken dip tube, causing cold water to mix with hot water at the top of the tank.
- Sediment buildup at the bottom of the tank, reducing efficiency. Flushing the tank can help.
Leaking water heater
Pooling water around the tank often indicates a leak, the cause can vary from minor to major.
Common causes of a leaking water heater include:
- Corrosion inside the tank, usually due to age or water quality.
- Faulty pressure or temperature relief valves (PRV or TPR).
- Loose fittings, pipe joints, or valves — especially over time.
- Internal component failure (e.g. heating element or tank lining).
- Sediment build-up causing tank damage from the inside.
- Condensation (often mistaken for a leak), especially in humid weather.
If you’re unsure, wipe the area and monitor. Still leaking? Give us a call — we can assess the situation fast.
Odd noises from your water heater
- Banging, popping, or rumbling noises usually mean there’s sediment buildup at the bottom of the tank.
- As the sediment hardens, water bubbles up underneath it, creating the noise.
- These sounds could also indicate pressure issues or component failure — call us for a quick diagnosis.
- Sudden or increasingly loud noises shouldn’t be ignored. They often precede a more serious issue.
Discoloured or smelly hot water
- Rusty, orange, or foul-smelling water is a sign of internal corrosion or bacterial growth.
- Most systems contain a sacrificial anode rod to prevent this. If the anode has worn out (usually lasts 3–5 years), it needs replacing.
- Replacing the anode is far more cost-effective than replacing the entire system.
- If your system is over 3.5 years old, call us with the make and model — we’ll let you know if an anode replacement is recommended.
Lukewarm water or slow reheating
If your water isn’t heating properly or takes too long to recover, your system may be:
- Too small for current demand.
- Suffering from a worn-out heating element.
- In need of a new tempering valve.
- Signs include inconsistent water temperature, long wait times for hot water, or water that’s too hot or too cold despite adjustments.
