When it comes to hot water system price or cost, Kalka residents can tap into a mix of Australian Government incentives and Queensland programs. Small-scale Technology Certificates (STCs) effectively act as a solar hot water rebate or heat pump hot water rebate, knocking thousands off the upfront heat pump hot water price or cost and solar hot water price or cost, depending on the system size and efficiency. There are also state-based schemes that can operate as a hot water rebate qld, and in some cases an electric hot water system rebate for high efficiency models. These discounts can reduce the system cost by a substantial percentage and shorten payback periods to just a few years, especially if you use timers or solar diversion to run your heat pump during the middle of the day.
If your current unit is struggling, leaking, or you are looking at a solar hot water tank replacement or hot water repair, it is a good time to compare heat pump vs solar hot water and even consider solar hot water vs electric hot water for your situation. The best heat pump hot water system for you might be different to your neighbour’s, depending on roof space, budget, and whether you already have solar.
