That sunshine, combined with high electricity prices and a big mix of renters and owners (over 4,500 rented dwellings, more than 2,200 owned outright and 2,300 with a mortgage), makes upgrading from older gas or electric hot water to a more efficient hot water technology the logical next step.

Federal Small‑scale Technology Certificates (STCs) apply to approved solar hot water systems and heat pump hot water systems, reducing the solar hot water price / cost and heat pump hot water price / cost at the point of sale. On top of that, Queensland hot water rebate programs often include a heat pump hot water rebate or solar hot water rebate, and there are schemes that support an electric hot water system rebate when you replace old gas hot water.
For many households in Railway Estate QLD, these incentives can knock 20–40% off the upfront hot water system price / cost.
