Common Solar Hot Water Problems

When your solar hot water system isn't working as expected, it can be frustrating. Common issues include having no hot water, lukewarm water, the system failing to boost during cloudy days, or water leaking from the roof collectors. You might also notice a failed solar pump, controller or sensor faults, tempering valve issues, reduced overall performance, or unexpectedly high electricity usage.

How Does A Solar Hot Water System Work?

A solar hot water system relies on several key components working together to harness the sun's energy. Roof collectors—either flat panel systems or evacuated tube systems—absorb solar radiation to heat water or a heat-transfer fluid. Circulation systems then move this heated fluid to a storage tank.

Because the sun isn't always shining, these systems include electric boosters or gas boosters to ensure a reliable supply of hot water. Controllers and sensors constantly monitor the temperatures at the roof collectors and within the tank, turning the circulation pump on and off as needed to maximize efficiency.

Why Has My Solar Hot Water Stopped Heating?

The most common causes are failed solar pumps, faulty controllers, sensor issues, booster faults or leaks within the collector circuit. Most problems can be diagnosed and repaired without replacing the entire system.

If your system has completely stopped heating, it could be due to a failed circulation pump preventing heat transfer, controller faults failing to activate the system, or sensor failures providing incorrect temperature readings. Airlocks, leaks, and booster faults can also disrupt the heating process.

Solar Hot Water Not Producing Enough Hot Water

If your system is producing some hot water but not enough to meet your needs, the issue often lies with faulty boosting or poor circulation. Sensor issues can cause the booster to engage too late, while increased household demand or incorrect system sizing can overwhelm the system's capacity. Extended periods of cloudy weather can also impact performance if the booster isn't functioning correctly.

Solar Hot Water Leaks

Leaks can occur in various parts of a solar hot water system. Roof collector leaks are common in older flat panels, while pipework leaks, tank leaks, and valve leaks can happen anywhere in the system. Tempering valve issues or circulation loop leaks can also lead to significant water loss. In many cases, components like valves and pipework can be repaired, but a leaking storage tank usually requires a hot water system replacement.

Solar Hot Water Pump Repairs

The circulation pump is the heart of a split solar hot water system. Pump failures often present as strange noises, circulation faults, or a complete lack of solar heating. Our technicians can diagnose pump issues and provide efficient replacements to restore your system's circulation.

Solar Hot Water Controller Repairs

The controller acts as the brain of your solar hot water system. Controller faults can manifest as blank displays, error codes, sensor communication failures, or booster control issues. We can troubleshoot and replace faulty controllers to ensure your system operates at peak efficiency.

Solar Hot Water Sensor Faults

Sensors located on the roof and in the tank tell the controller when to activate the pump. Roof sensor issues or tank sensor issues can lead to temperature inaccuracies and significant system performance problems. Replacing a faulty sensor is a straightforward repair that can dramatically improve efficiency.

Electric And Gas Booster Faults

Solar hot water systems rely on boosting during cloudy days or high-demand periods. We repair electric booster elements, booster thermostats, gas booster ignition problems, and booster control faults. Ensuring your booster works correctly is essential for a consistent hot water supply.

Flat Panel Solar Hot Water Repairs

Flat panel systems are robust but can experience issues over time. Whether you have a roof-mounted system (thermosiphon) or a split system, we handle collector leaks, circulation issues, and common repair scenarios specific to flat panel technology.

Evacuated Tube Solar Hot Water Repairs

Evacuated tube systems offer excellent performance, especially in cooler climates. Our repairs cover tube replacement, manifold faults, sensor issues, and circulation faults to resolve any performance problems you might be experiencing.

Repair Or Replace?

Deciding whether to repair or replace your solar hot water system depends on its age, the condition of the collectors and tank, and the repair costs. If the tank is leaking or the system is over 15 years old, a replacement might be the most cost-effective option. However, if the issue is a faulty pump, sensor, or element, a repair can restore your system's energy savings and extend its lifespan.

We Repair All Major Solar Hot Water Brands

Our solar-accredited technicians have extensive experience repairing all major brands, including Envirosun, Rheem Solar, Edwards, Chromagen, Apricus, Rinnai Solar, Thermann Solar, Beasley, Solahart, and Saxon. We carry a wide range of parts to ensure fast, reliable repairs.

Why Solar Systems Are Often Worth Repairing

Solar hot water systems are a significant investment that provides substantial energy savings over their long lifespan. Components like pumps, controllers, and sensors are highly repairable. Repairing these parts is often much more cost-effective than a full replacement, allowing you to continue enjoying the environmental and financial benefits of solar energy.
