Everlast solar hot water system repair diagnosis.

Once onsite at the property, our solar hot water specialist Steve, ran a series of tests to ascertain what the problem was with the existing solar hot water system.

Thankfully, the tests revealed that the problem was with the existing Everlast tank.  The solar ground kit, pump and tubes were all working correctly.

Steve discussed replacement tank options and costs with the customer and they decided to replace the Everlast with a new Therman electric solar hot water heater (model: TH315GLE).

The new tank was installed in the same location as the old one.  After some simple adjustments to the existing cold and hot water pipework – a standard procedure when installing a new hot water system – the customer was back enjoying trouble-free solar hot water (with electric backup) within a few hours.

A new tempering valve needed to be installed to comply with AS3500 Plumbing Code requirements.

Solar hot water rebates – Claiming STCs

What is the Small Scale Renewable Energy Scheme?

The Federal Government introduced the Small-scale Renewable Energy Scheme to encourage individuals and small businesses to install renewable energy systems in their home or business.

Solar hot water heaters and air source heat pumps are appliances that are applicable to claim rebates under the scheme.

How does the Small Scale Renewable Energy Scheme work?

The Small Scale Renewable Energy Scheme works through the creation of small-scale technology certificates (STCs).  The amount of CO2 emissions saved or generated by an appliance are calculated into STCs.  Each STC represents 1 megawatt hour (MWh) of electricity displaced over a 10 year period. The number of STC’s created varies with the size and model of solar water heater and the region (or zone) in which the unit is installed. The value of an STC is not fixed and varies depending on market factors.

Do STCs reduce the price of a new hot water system?

STCs can reduced the price of your new solar hot water system

By installing a solar water heater or heat pump, you may be eligible for STCs. These STCs can be used to reduce the purchase price of your new solar hot water system, potentially saving you thousands of dollars.

Once you install a solar water heater, the STCs produced can be traded and sold on the open market.  Most customers assign the right to create your STCs to their hot water heater installer (i.e. Cheapa Hot Water) who will then pay you the value of the STCs as an upfront discount on your solar hot water system.  Typically, when we install a solar hot water system for a customer we calculate how may small-scale technology cerficiates (STCs) will be created over the life of the solar hot water system, we then pass on an up-front discount that is equivalent to the value of the STCs.

It’s important to note that the value of STCs is not fixed and can vary over time.  When you contact us about switching from gas or electric to a more energy efficient solar hot water system, we can explain the process in more detail and any discount that may be applicable.
