Solar Hot Water Systems – Maximum Efficiency With Correct Servicing and Maintenance

Solar hot water systems need to be maintained to the manufacturer’s instructions to maintain maximum efficiency. Whywait Plumbing Services have been specialists in solar hot water systems for installation and repairs as your local, reliable and professional Gold Coast Plumber for 40 years, since 1976.

Solar hot water has never been rocket science. In fact, it’s simple science because the sun continually heats the water that is circulating through the solar collector panels which are then stored in a tank waiting for you to use it.

If you have any questions about solar hot water not covered below, contact our friendly team – they’ll be happy to help you. You can also check out our range of solar hot water systems and rebate information plus you can always phone us for a no-obligation solar hot water quote.

All solar hot water systems require servicing and maintenance to ensures that the systems are operating at peak efficiency which increases their operational lifespan and ensures you are saving you money on energy costs.

Service and maintenance of solar hot water systems are not extensive and little different to electric or gas systems, but it is specialist work because when a solar hot water system fails, it tends to be sudden, leaving you without hot water.

6 Month Regular Maintenance Service

Every solar hot water system has a pressure relief valve installed on the storage tank to prevent the system overheating and becoming excessively pressurised.

All manufacturers recommend that the lever on the relief valve be eased every six months to ensure that it opens and closes correctly.  This is something that you can do yourself although if your tank is on the roof, you need to take care of working on the roof.

It is also the ideal time to give the solar collector panels a clean with water and a soft cloth to maintain maximum heating efficiency.

12 Month Regular Maintenance Service

An annual checkup cannot be done yourself because all solar hot water systems have a high-performance tempering valve that delivers hot water to your home at 50ºC to ensure that the risk of your family being scalded is reduced.

As the sun is an uncontrolled heating source, the tempering valve on your solar hot water system is subject to operating extremes. For this reason, routine maintenance, servicing, and testing are required every 12 months as per AS 4032.3-2004 plus we issue you with a compliance certificate to cover you for insurance purposes.

5 Year Regular Maintenance Service

Every manufacturer recommends that your solar hot water system is serviced every five years.  This comprises of the following tasks:

  • Replacement of sacrificial anode
  • Flush out the panels to improve efficiency
  • Check all valves and replace as required
  • Check all electrical components and replace as needed
  • Check all panel connection seals and replace as needed
  • Wash down and clean storage tank and solar collector panels
