Ongoing hot water repair and solar hot water repair work also drives some households to upgrade rather than simply replace like‑for‑like, especially when a solar hot water tank replacement is due.
Hot Water Rebates, Tariffs & Savings
Around Cornelian Bay, many owners and landlords are eyeing off hot water upgrades – 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 heating system.
