FAQs
What are the most common signs that my hot-water system in Cowan needs an upgrade?
Look for a significant drop in water temperature or pressure, rusty or discoloured water, unusual banging or hissing noises from the tank, visible leaks, or a system that’s more than 10–12 years old. Any of these symptoms suggest that the unit is nearing the end of its service life and upgrading will improve reliability, safety, and efficiency.
Which type of hot-water system is best suited to Cowan’s climate and water conditions?
For Cowan’s temperate climate and moderate water hardness, heat-pump and high-efficiency gas storage systems are popular options. Heat-pump units use ambient air to heat water and can cut energy use by up to 65 %, while modern gas storage systems provide fast recovery rates for larger households. Solar-boosted systems can also perform well thanks to Cowan’s good year-round solar exposure, with an electric or gas booster for cloudy days.
How long does a typical hot-water upgrade take, from removal to commissioning?
A straightforward like-for-like replacement can usually be completed in 3–5 hours. If you are switching technologies—for example, from electric storage to a heat-pump or solar-boosted system—allow 5–7 hours to cover extra plumbing, electrical, or roof work. We handle all plumbing, gasfitting, wiring, testing, and council compliance on the same day whenever possible to minimise downtime.
Will upgrading my hot-water system really lower my energy bills?
Yes. Aging electric storage units can lose 25 % or more of their heat through standby losses. By upgrading to a heat-pump, solar-boosted, or high-efficiency gas unit, most Cowan households see energy savings of 30–70 %. Over the system’s lifespan, those savings typically offset the upfront cost and provide long-term reductions in both energy expenses and greenhouse-gas emissions.
Do you remove and responsibly dispose of my old hot-water unit?
Absolutely. As part of every upgrade, we disconnect, drain, and remove the existing unit, then transport it to a licensed recycling facility. Metals, insulation, and other components are separated for recycling or safe disposal, ensuring that nothing ends up in landfill unnecessarily and you have one less thing to worry about.
Are there any government rebates or incentives for hot-water upgrades in Cowan?
Yes. NSW homeowners may be eligible for Small-scale Technology Certificates (STCs) when installing accredited heat-pump or solar hot-water systems, which can reduce upfront costs by hundreds of dollars. Additional rebates are sometimes available through the NSW Energy Savings Scheme (ESS) and local council sustainability programs. We handle the paperwork, calculate your rebate value on the spot, and apply it as an instant discount on your installation.
