Solar Hot Water System Spare Parts — Brisbane & Sunshine Coast

SunCity Hot Water supplies and fits genuine solar hot water spare parts across Sunshine Coast, Brisbane and Gympie. Whether your system is leaking, not heating or completely broken down, our specialists carry the parts needed to get it running again fast.

Solar Hot Water Spare Parts We Supply & Fit

We stock a comprehensive range of OEM and compatible solar hot water spare parts for all major brands. Our team can source and fit the right part for your system, minimising downtime.

Solar Collectors & Evacuated Tubes

Flat plate collectors and evacuated tube replacements for all major solar brands. Cracked tubes or a damaged collector is the most common cause of a solar system producing no hot water.

Solar Storage Tanks & Cylinders

Stainless steel and vitreous enamel solar storage tanks, both roof-mounted and ground-mounted split systems. We can replace your cylinder or reline an existing one.

Solar Pump Stations & Circulation Pumps

Faulty solar circulation pumps are a frequent cause of solar hot water not heating. We stock pump stations and individual pump heads for all common systems.

Solar Controllers & Differential Controllers

Solar differential controllers manage when your pump runs by comparing collector and tank temperatures. A failed controller means your system will not use free solar energy efficiently.

Solar Check Valves, Relief Valves & Tempering Valves

Pressure-temperature relief valves, check valves and tempering valves keep your system safe and compliant. These are wear items and should be inspected every 5 years.

Sacrificial Anodes & System Seals

Sacrificial anodes in solar storage tanks protect the cylinder from corrosion. Replacing your anode every 3 to 5 years extends tank life significantly.

Is Your Solar Hot Water System Not Working?

Solar hot water faults usually come down to a failed component. Below are the most common issues our specialists diagnose and fix across Brisbane and the Sunshine Coast.

Solar Hot Water System Producing No Hot Water

If your solar hot water is not working, check whether the pump station is running during daylight hours and whether the controller is displaying correctly. A tripped pump, failed controller or shaded collector are common causes.

Solar Hot Water System Leaking

Solar hot water system leaking is often traced to a failed pressure relief valve, corroded fittings or a cracked collector panel. Left unfixed, leaks cause water damage and reduce system efficiency.

Solar Hot Water Boost Not Working

When solar input alone is insufficient, your system relies on an electric or gas boost element. A failed boost element or thermostat means no hot water on overcast days.

Solar Controller Fault or Error Code

Controller error codes indicate temperature sensor faults, pump faults or wiring issues. Our specialists can diagnose and replace faulty controllers on-site.

Discoloured or Smelly Hot Water from Solar System

Brown or smelly water from a solar system usually means a depleted sacrificial anode allowing tank corrosion. Early replacement saves the tank and restores water quality.
