Solar Thermal Service
A solar hot water service involves the maintenance, inspection, and repair of a solar hot water system, which typically uses solar panels (collectors) to harness energy from the sun to heat water.
Regular servicing (usually every 2-3 years) This helps prolong the life of the system, ensures it’s working efficiently, and can prevent costly repairs later on. The anti-freeze (glycol) breaks down when exposed to high temperatures so in many cases will need to be replaced, this helps protect the copper manifold during winter months, it also ensures an optimum heat transfer temperature.
Here’s what is typically involved in a solar hot water service:
1. Inspection:
- Checking the solar panels or collectors for dirt, debris, or damage. Clean the panels if needed to ensure they are absorbing sunlight effectively.
- Inspecting the roof-mounted components, such as the panels, piping, and support structure.
- Checking the storage tank for corrosion or leaks.
2. Testing and Monitoring:
- Ensuring the system is working efficiently, such as checking the temperature of the water in the tank and ensuring it is being heated adequately.
- Checking the controller and thermostat to ensure they're functioning correctly.
3. Checking the Pump and Valves (for systems with pumps):
- Ensuring that the circulation pump (if applicable) is working properly, as it's responsible for circulating the water from the solar panels to the storage tank.
- Checking valves and pressure relief valves to ensure they are in good working order.
4. Flushing the System:
- Some systems may require flushing to remove sediment or buildup that may impair efficiency. This is especially common in systems with hard water or mineral-rich environments.
5. Re-calibrating the System:
- Ensuring the system is correctly calibrated, including settings for the temperature, and that it’s operating optimally.
6. Checking the Backup Heater:
- If your system has a backup heater (e.g., electric or gas), checking that it works and kicks in when solar heating is insufficient (e.g., on cloudy days).
7. System Test Run:
- Running the system through a full cycle to ensure everything operates as expected, including checking for leaks, noises, or anything unusual.
