Hello @anthonyv40c 

Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about your solar hot water system.

Please note that any plumbing work must be carried out by a licensed plumber for safety and compliance.

In this particular situation, I suggest engaging the services of a plumber. It could possibly be the temperature relief valve, but only the plumber would be able to confirm the real cause of the failure of your hot water system.  

If you need further assistance, please let us know.

Hi @anthonyv40c 

In  case of expensive repairs.

These  days it is so much better to spend your money of solar  electricity and  panels and  use  all the excess electric daylight power to heat your hot water  for free via a standard   electric hot water service,  Rather than complicated  solar hot water solar systems.

Have a timer on  electricity (some  hot water systems  have timers  built in) So it only heats 10 am to 4 pm

Have the 300 plus litres to last the night through for family and free reheat next  day.   Rainy days costs grid power to  heat

Hope you repairs   inexpenxsive.
