Hot water systems in Selwyn
Across Selwyn and the 3737 postcode, more locals are rethinking their old gas and electric hot water system and switching to efficient options like a heat pump hot water system, solar hot water system or modern electric hot water system. With an average household size of 2.3 people and a big share of homes owned outright or with a mortgage, hot water is a major running cost you can actually do something about. Many families and retirees on median household incomes around $1,211 a week are looking for ways to trim bills without sacrificing comfort.
Selwyn’s climate is well suited to efficient hot water. The nearby Mount Hotham weather station records mean daily solar exposure of about 15.4 MJ/m², which is roughly 4.3 kWh/m² per day over the year. That solid sunlight helps a solar hot water heating system or heat pump hot water system perform strongly, even with our chilly winters, and makes upgrading from older gas or resistive electric units a logical next step. For many Selwyn homeowners, annual hot water energy savings can easily reach hundreds of dollars when they move to a more energy efficient hot water system.
Most dwellings in 3737 are separate houses, with 1,818 occupied private dwellings and plenty of three- and four-bedroom homes, so hot water demand is steady, especially for families and multi-generational households. Hot water can be one of the largest single energy users in the home, so it is no surprise that efficient hot water systems installed in the area are growing in popularity as people chase lower running costs and quieter, all-electric homes.
When it comes to brands, you will often see Rheem solar hot water and Rheem heat pump hot water systems on local properties, along with Rinnai solar hot water and premium units like the Sanden heat pump. Chromagen solar hot water is another option some Selwyn households consider when comparing the best hot water system Australia has to offer. Choosing the best heat pump hot water system or solar hot water tank replacement depends on your roof space, existing plumbing, tariff and whether you already have rooftop solar.

As more homes add rooftop solar, solar hot water vs electric hot water and heat pump vs solar hot water have become common conversations when planning a hot water upgrade.
Hot Water Rebates, Tariffs & Savings
Selwyn homeowners are increasingly comparing electric hot water vs gas hot water and solar hot water vs electric hot water as energy prices rise. The good news is that a range of Australian Government incentives can bring the hot water system price down. Small-scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pump hot water systems, effectively acting as an upfront discount. On top of that, Victoria offers state-based schemes that can provide a solar hot water rebate or a heat pump hot water rebate, and in some cases an electric hot water system rebate when replacing inefficient units.
These hot water rebate VIC programs can reduce the heat pump hot water price or solar hot water price by a substantial percentage, shortening payback times to just a few years for many Selwyn households. With typical savings of hundreds of dollars per year, especially when you use timers or solar diversion to run your system when your PV is generating, an energy efficient hot water system quickly pays for itself. For many locals, the real question is no longer whether to upgrade, but which mix of hot water installation, tariff and technology will deliver the best long-term value.
If you live in Selwyn and your current unit is older, noisy or costing a fortune to run, now is a smart time to look at efficient hot water options.
