Stiebel Eltron - thermal battery savings

Your Stiebel Eltron heat pump can act as a thermal battery

by using excess electricity from your solar power system your Stiebel Eltron thermal battery can store you up to 3kWhs of electricity in the form of hot water. The savings from this can be calculated as:

The cost per kWh for your electricity minus the feed in tariff you would receive for exported power. At the time of writing the average cost of electricity in SE QLD is 25 cents per kWh and the value of exported power 6 cents per kWh - the annual saving from your thermal battery can be as much as $200 per year on top of the savings you already enjoy from the ultra efficient Stiebel Eltron heat pump

How much can I save with a Stiebel Eltron Heat Pump?

Stiebel Eltron Heat Pumps are extremely efficient

and can save you up to 74% when compared to a conventional electric hot water system

How much energy can I save with an Rinnai solar hot water system?

Up to 80% of your hot water running costs

Electric hot water systems in general are the largest users of energy in most Australian homes, so it is important to consider all the factors before selecting an Rinnai solar hot water system. High efficiency, correctly sized hot water systems can directly lower the running costs of a family.

The table above indicates where energy is typically used in an average household. Naturally this varies from house to house but the common factor is that hot water will nearly always be the largest consumer of energy.

Increased levels of greenhouse gases have been identified as one of the major contributors to climate change, so anything that can help reduce our carbon footprint, is beneficial to the environment.

When purchasing a new hot water system, many people simply put in what was there before without considering the environmental impact of their decisions. The chart above clearly shows that if you make an informed decision and you think about the consequences to the environment, you in fact have the opportunity to make a difference. The purchase of a Rinnai hot water system is a clear step in the right direction. 

Running costs for Rinnai hot water systems vary depending on the type of system installed (storage cylinder or continuous flow) and the fuel used (Solar, Gas or Electricity)

The table above gives an indication of the annual running costs of various common hot water systems used in Australia. As hot water use varies between households and locations, this graph will change accordingly. The calculations are based on a family of four, having one five minute shower a day each and using cold water for clothes washing. It is a comparative guide only, based on various government websites.

Small Scale Technology Certificates (STC)

STC's or small scale technology certificates are a Federal Government incentive to purchase eligible solar power and solar hot water systems. The SunWorks Solar Centre is a registered STC agent.

The SunWorks Solar Centre is a registered STC agent with Clean Energy Regulator as such we are able to bypass middlemen and can offer you the best possible price for your STC’s.

Small-scale Technology Certificates, or STCs, are a tradeable commodity attached to eligible installations of renewable energy systems (including solar panels, solar water heaters and heat pumps).

Under the Federal Government’s Small-scale Renewable Energy Scheme, when you install an eligible system, you may claim a set number of these STCs. This number is based on the amount of electricity in megawatt hours (MWh):

  • generated by your small-scale solar panel, wind or hydro system over the course of its lifetime of up to 15 years; or
  • displaced by your solar water heater or heat pump over the course of its lifetime of up to 10 years,

where one STC equals one megawatt hour (MWh) of electricity generated or displaced.

The number of certificates you can claim may vary depending on your geographic location, what you’re installing, whether your installation is eligible for Solar Credits, and/or the size and capacity of the installed system. For example, a 1.5kW solar panel system on the Sunshine Coast might be eligible for a minimum 31 STCs, while a solar water heater might be eligible for a minimum of 20 STCs.

Solar Credits is a mechanism which increases the number of STCs that can be created for eligible installations of small-scale solar panel (photovoltaic – PV), wind, and hydro systems.

You can calculate the number of STCs claimable by a system by using the calculators on the Clean Energy Regulator website

STCs are not a rebate. The value of STCs is not fixed* and varies from time to time. The Owner of the solar power or solar water heater can assign the right to create STCs to The SunWorks Solar Centre and The SunWorks Solar Centre will reimburse the Owner for the value of the STCs via a point of sale discount.

*a fixed price of $40 is available if STCs are sold via the STC clearing house. We do not sell our STC's through the clearing house and if you wish to go down this path you should be aware of the following

• Small-scale technology certificates (STCs) are not a rebate, and completing this creation process is not an application for a Government rebate. You will not qualify for any Government-based financial recompense at the completion of this process.
• Creating STCs for sale can be complex and has significant administrative requirements, legal implications, and may involve fees.
• If you require rapid financial recompense for your certificates, or a simpler process, simply assign your right to create the STCs to The SunWorks Solar Centre.

• If you decide to create your own STCs you will be required to:

  • Pay full price for your system;
  • Organise the installation of your system, ensuring it is compliant with the Renewable Energy Electricity Act 2000 and associated Regulations;
  • Create the STCs in the REC Registry;
  • Find a buyer for your STCs (including using the STC Clearing House)
  • Manage payment for the STCs.

Neither the Clean Energy Regulator nor The SunWorks Solar Centre can manage any of these processes for you, and cannot intervene in any process outside of STC creation.  The Clean Energy Regulator can provide advice only.
