This is a Rinnai solar hot water system we installed yesterday in Bullsbrook. We replaced the existing Solahart unit with its glycol filled panels with Rinnai’s FTC panels which are suitable for Perth’s frost prone areas. (Read our blog about frost proof solar hot water systems). We replaced Solahart’s vitreous enamel tank with Rinnai’s Sunmaster…
This week we installed a Rinnai close coupled solar hot water system with a 330 litre tank and two Excelsior panels on side pitch brackets for a tenanted property. It’s not something we do often because ideally you will have your panel and tank flush to the roof for a more sleek appearance. The brackets…
If you live in an area that hits temperatures approaching zero degrees you need the right solar hot water system. To show you how frost can affect your system, let me first explain how it works. Standard solar hot water panels contain copper pipe (risers) filled with water. This water circulates around the panels where…
Solar hot water manufacturer Rheem has announced that it will be closing their Solahart solar hot water manufacturing plant in Welshpool, Western Australia at the end of 2015 with the loss of around 100 jobs.

With a change in Government, the legislation to repeal the carbon tax has been introduced into the Australian Parliament. (1) The Direct Action Plan (2) is part of the Coalition’s attempt to achieve a renewable energy target of 5% emissions reduction by 2020 (compared to 2000 levels). One of the Direct Action Plan initiatives is…
Heat pump water heaters are relatively complex compared to other water heaters. This means that there is a variety of designs, energy efficiency and performance in available heat pump water heaters.
Heat pump water heaters operate using a refrigeration cycle that moves heat from a high temperature source (the outside air) to a low temperature destination (the hot water in the tank). In nature heat flow tends to go from higher to lower temperatures. Heat pumps mimic this natural flow by using a refrigerant that boils…

The Small-Scale Technology Certificate (STC) price from Green Energy has today risen to $37. This is the highest level since around June 2010.
Under the Small-scale Renewable Energy Scheme, eligible hot water and power generation systems are entitled to a number of Small-scale Technology Certificates (STCs) usually as a deduction from the point of sale price. Solar and Heat Pump Hot Water Systems Approved solar hot water and heat pump hot water systems are eligible for STCs. STCs…
