Fix Solahart hot water system.

We were recently contacted on Sydney’s Northern Beaches whose Streamline Solahart solar hot water heater had stopped producing hot water.

Once onsite, our solar hot water specialist John ran a series of tests to ascertain what was causing the problem.  Within no time, it was obvious the problem was with the old Rheem Salmson hot water circulation pump.  John was able to get a new, replacement pump from the truck and the system was back up and running within an hour or so.

Whilst on site, John replaced the TPR valve to ensure the hot water system complied with Australian plumbing standards.  John also ran a series of standard servicing tests in case other parts were showing signs of wear and tear and were likely to fail in the not-too-distant future.  Thankfully, there appeared to be no further issues and the customer should enjoy trouble-free hot water for the next few years (at least).

To enjoy further savings on their energy bills and mitigate running out of hot water during winter and cloudy weather, John suggested the customer make the switch from off peak 1 to off peak 2. Scroll down for more information on the difference between off peak 1 versus off peak 2.

off peak 1 vs off peak 2 hot water

Off Peak 1 versus Off Peak 2 Electric Hot Water

Running out of solar hot water? Consider switching from off peak 1 to off peak 2.

There are 4 types of electricity tariffs for hot water systems:

  • Off peak 1
  • Off peak 2
  • Continuous (or day rate)
  • Time of use

Off peak 1 uses electricity to heat your hot water between 10pm and 7am.  This offers a cheap rate and suits smaller households with 1-2 people who don’t use a lot of hot water.

Off peak 2 is better for larger households and electricity is used to heat hot water for up to 16 hours a day. There is less change of hot water running out on cloudy days or times of excessive hot water usage such as in afternoons and evenings or during winter months.


If you have any questions about the benefits of switching from off peak 1 to off peak 2, don’t hesitate to contact our solar hot water specialists. We’re here to help. Call 0410 693 532.
