Sustainable Technology

Our residential consulting service provides you with free-of-charge technology solution recommendations tailored to meet your specific energy requirements. 

Sustainable energy solutions are an excellent way to save money over time! Quality solar systems and heat pump water heaters may have a higher upfront cost, but they pay off in the long run. Low-cost options often lead to failures and unexpected expenses; however, quality systems can end up being just as affordable after rebates! 

Keep in mind that energy efficiency upgrade rebates are linked to the tested system's energy efficiency, so the highest efficiency products receive the most rebates. Insulation is crucial for energy efficiency. Additionally, upgrading to energy-efficient air conditioners can help lower your bills and reduce emissions! 

When selecting heat pumps, ensure they’re suitable for colder climates to provide efficient hot water and heating. It’s all about making smart choices for your home!

The Ecogenica heat pump depicted in this photo was tested over a two-year period in a four-person household in Sydney. 

Monitoring the water heater indicated that power consumption rarely exceeded 3 kWh per day. Electric and gas hot water contribute significantly to the household energy bill, nearly 40%. So the saving delivered by the Ergogenica heat pump water heater makes a big difference reducing household energy savings.

To reduce this expense, the first step involves reevaluating hot water production methods. Imagine the benefits of harnessing the sun’s abundant and free energy, 

converting it into electricity through solar panels, and efficiently powering a heat pump for hot water production. Providing the industry’s most advanced and efficient hot water systems for lasting savings and quality outcomes.

At Sustainable Energy Systems, we specialise in conducting thorough energy audits tailored to your business needs. Our team assesses energy consumption patterns, identifies inefficiencies, and provides actionable recommendations. This process helps you save costs and reduce your carbon footprint, making your operations more sustainable and profitable.

Battery storage enables the retention of excess energy generated by renewable sources such as solar and wind, making these sources more reliable and predictable. This technology helps balance the intermittent nature of renewable energy with the consistent demand for electricity.

**Cost Savings:**  

By storing energy when prices are low and utilizing it during peak demand periods, battery storage can reduce energy costs for both consumers and utilities. This is especially advantageous for individuals with solar panels, as it allows them to use a greater portion of the energy they generate and lessens their dependence on the grid.

**Environmental Benefits:**  

Battery storage decreases reliance on fossil fuels and contributes to a cleaner energy system. By facilitating increased integration of renewable energy, it helps lower carbon emissions and combat climate change.

In NSW, insulation helps regulate indoor temperatures and reduces energy consumption. The National Construction Code (NCC) mandates minimum insulation requirements for new homes, with R-values (a measure of thermal resistance) increasing with building location and climate. For example, Sydney and other cooler areas may benefit from R4.0 or higher ceiling insulation. Bulk insulation, like batts or blankets, is suitable for colder climates, while reflective insulation, like foil-backed materials, is better for warmer areas.

Key aspects of insulation :

• R-values: Higher R-values indicate better insulation performance. 
• National Construction Code (NCC): Sets minimum insulation requirements for new builds. 
• Climate considerations: Choose insulation types and R-values appropriate for the local climate. 
• Bulk insulation: Suitable for colder climates, trapping air in layers. 
• Reflective insulation: Ideal for warmer climates, reflecting heat away from the house. 
• Spray foam: Popular for filling cracks and gaps, but consider potential health risks associated with certain types. 
• Building fabric thermal insulation: Must comply with the national BCA provisions. 
• Ceiling insulation and downlights: Ensure proper clearances to avoid fire hazards. 
• Advice for insulation and draught proofingInsulation depends on the climate Bulk insulation is suited to colder climates –
• Thermal insulation in a building must comply with the national BCA provisions of 3.12. 1.1. ... 3.12. 1.4(d) fNational Construction Code

Our consultations will determine if you can access discounts that lower the cost of installing the new energy-efficient air conditioner, when we upgrade the old one with a more efficient model.  

Upgrading to a more energy-efficient air conditioner can help you:  

• save money on your power bills in the long-term by using less energy to heat and cool your home or business
• reduce maintenance costs with newer systems that are more efficient and reliable  
• reduce your emissions and be an active part of helping NSW reach net zero by 2050. 

The air conditioning rebate is provided as an upfront discount in the quote provided to you for the installation of a new high efficiency air conditioner. During the initial consultation we will confirm If you’re eligible, and advise on the discounts which can range between:

• $340 and $560 if you install a new 6kWh air conditioner system
• $440 and $730 if you replace an old air conditioner with a 6kw split system.

Hydronic heating: To understand if your hydronic project is suitable for a heat pump, we have found the first thing a client needs to understand is the difference between a hydronic heat pump and a domestic hot water heat pump. Domestic hot water heat pump range from 2.5 to 3.8 kW in size.

 To ensure fast recovery rates (time to heat the water) you should always select the most powerful and efficient heat pump water heater. Many heat pump water heaters use small 2 kW to 2.5 kW rated compressors which may require boosting in Winter. So you need to consider the cold weather performance. 

Cold weather performance is especially important if your considering a combined hot water, heating and cooling system. We find that the average Australian home requires around 15 kW to 20kWs. In Europe they normally only require around 6kW's as the homes are much better insulated and tend to be smaller with less open planned rooms.

Another important aspect of a hydronic heat pump is that it is built and designed to operate in winter conditions at negative temperatures. Some heat pumps won’t generate hot water when the temperature gets below -5C.
