Solar hot water repairs Penrith.

Our Sydney solar hot water specialists recently attended a customer’s home in Penrith when they called us after waking up with no hot water.  The customer had been encountering problems with their old rooftop solar hot water system for some time and, on this day, it finally stopped working completely.

We organised a convenient time to visit the Penrith property and, after weeks and weeks of rain in Sydney and along the entire NSW east coast, it was a beautiful day.

Once onsite, our solar specialist, Steve, ran a series of tests to determine the problem. As is often the case, once there is one problem, it typically leads to other parts failing. That’s what happened with this solar HWS.

Unfortunately, replacement parts for many older hot water systems are no longer manufactured and there is no option but to install a new one. On a positive note, modern hot water systems are more economical to run and, due to their increased efficiency, are kinder to the environment.

What size solar hot water system should I install?

When installing a new hot water system, we always discuss with the customer their household hot water usage requirements.  This ensures we install the right hot water system for their usage now and into the future.

Living at the home were mum, dad and two, young ‘tween’ children.  First, we calculated the hot water usage of the ‘humans’ in the home.  Next, we look at the hot water usage demands of appliances such as washing machines and dishwashers which can use as much hot water as one person. We also discuss whether their hot water usage demands are likely to change in the future.  For example, teenagers use more hot water than younger children.

With all this in mind, we recommended a new Rheem Hiline stainless steel solar hot water system with a generous 300-litre rooftop tank (model: 52L300/2L).  This could be installed in the same location as the previous hot water heater, saving the customer time and money.
