Hot Water Rebates, Tariffs & Savings

Right across WA, including Mills Lake, there is growing interest in replacing old gas or electric units with a heat pump hot water system, a more efficient electric hot water system, or a solar hot water system. Federal incentives like Small‑scale Technology Certificates (STCs) apply to eligible solar hot water installation and heat pump hot water installation, effectively acting as an upfront discount. On top of that, state programmes can offer a heat pump hot water rebate or solar hot water rebate, and there may also be an electric hot water system rebate when you move away from gas. These incentives can easily trim the hot water system price or cost by a substantial percentage, bringing the heat pump hot water price or cost and solar hot water price or cost down to something far more manageable.

For many Mills Lake households, that means the payback period on an upgrade can drop to just a few years, especially if you already have solar and use timers or solar‑diversion controls so your solar hot water vs electric hot water bill comparison really stacks up. If your existing solar hot water tank replacement is due, or your current unit needs solar hot water repair or general hot water repair, it is often smarter to put that money towards a new, energy efficient hot water system instead.
