There are several reasons that might explain why your solar hot water system isn’t working, but these can often come down to the same 5. In this blog post, our team explore each of them whilst also providing tips on how to check for them.
1. Your system isn’t properly sized for your home
How to check for this issue
- Check the size of your collectors.
- Check the size of your storage tank.
- Check the location of your solar collectors.
2. You have hard water
In solar distillation, water is created via the evaporation of steam coming from the sun. Often, this leaves behind impurities like minerals and salts. This can clog the system and prevent it from working properly.
How to check for this issue
- Check it regularly for mineral build-up.
- Check for any white powdery substance on the walls of the tank.
- Check for any cloudy water coming out.
3. You live in a cloudy climate
If you live in a cloudy climate, your solar hot water system might not work well. This is because solar hot water systems rely on the sun, and if there isn’t any, the water won’t get as hot.
How to check for this issue
- Ensure that the collector is clean and free of debris.
- Inspect the pipes and fittings for leaks.
- Check the fluid level in the storage tank.
4. Your system isn’t maintained
Solar hot water systems are a great way to save money on your bills, but if they’re not properly maintained, they can stop working properly. Poorly maintained solar hot water systems can develop leaks, which can lead to lost hot water.
How to check for this issue
- Ensure that your system is properly insulated to prevent heat loss.
- Check the temperature of your water regularly to ensure that it is being heated sufficiently.
- Have your system serviced by a qualified technician at least once per year.
5. You have an older system
If you have an older solar hot water system, there are a few reasons why it might not be working as efficiently as it used to. The main reason is that the solar panels may not be as effective at collecting energy from the sun. This is because, over time, the panels can become covered with dirt and dust, which can reduce their efficiency.
How to check for this issue
- Check for leaks by looking for any drips or puddles around the base of your system.
- Check the water pressure in your system
- Check the circuit breaker to make sure it hasn’t been tripped.
