Hot water systems in Stow
Across Stow and the wider 5461 district, more households are looking at upgrading to an energy efficient hot water system instead of just replacing like-for-like when an old unit fails. With average household sizes around 2.4 people and most dwellings being separate houses on decent blocks, there’s plenty of roof and yard space to make the most of the sun and off‑peak power for a modern solar hot water system, heat pump hot water system or efficient electric hot water system.
The local climate is ideal for efficient hot water. The nearby Wanappe weather station records mean daily solar exposure of about 17.8 MJ/m², or roughly 5 kWh/m² per day over the year. That solid solar resource helps a solar hot water heating system or heat pump hot water system perform well, slashing running costs compared with older gas or resistive electric units. With many homes in the area owned outright or with a mortgage, and median household incomes sitting in the mid‑range, upgrading from gas or an old electric hot water system to a more efficient option is a practical way to lock in long‑term savings and reduce bill shock. Over a year, those hot water energy savings can be a noticeable chunk of a Stow family’s power bill.
In the 5461 postcode there are more than a thousand dwellings, most with three or four bedrooms, so hot water demand is steady, especially for families and older residents who are at home more. Hot water can make up 20–30% of household energy use, which is why choosing the most efficient hot water system you can is so important. Locals are comparing electric hot water vs gas hot water, and increasingly asking about heat pump vs solar hot water to decide what suits their roof space, budget and lifestyle. Brands like Rheem, Rinnai, Sanden and Thermann are common choices here, from rheem solar hot water and rinnai solar hot water through to a premium sanden heat pump or a robust rheem heat pump hot water unit. Many homeowners look for the best hot water system Australia can offer in their price bracket, or drill down to find the best heat pump hot water system for their particular needs.
Typical hot water system price or cost will depend on size, brand and whether it’s a straight electric hot water installation or a full solar hot water installation with roof collectors and a solar hot water tank replacement.

• Replacing an old electric system with a heat pump: $400–$800 per year • Switching from gas to a heat pump: $300–$600 per year • Switching from gas to a solar hot water system: $300–$700 per year • Upgrading an old electric unit to a modern electric hot water system with rooftop solar: $250–$500 per year
