Hot water systems in Rheola
Across Rheola and the 3517 district, more households are switching to energy efficient hot water systems – from a modern electric hot water system through to a heat pump hot water system or full solar hot water heating system. With a mostly older population, an average household size of 2.2 people and 296 homes already owned outright, many locals are looking to cut running costs without sacrificing comfort.
Rheola’s strong sunshine makes that easier. The Glenalbyn (Brenanah) weather station records an average solar exposure of around 17.3 MJ/m² per day – roughly 4.8 kWh/m² per day – which is excellent for both a solar hot water system and a high efficiency heat pump hot water system.

With 587 occupied private dwellings and a high share of separate houses, hot water demand is steady, but not extreme. That makes a 250–315 litre hot water system a good fit for many households, while smaller 160–200 litre units can suit couples and retirees. Local experience shows that hot water energy use can be one of the biggest single loads in an all‑electric home, so shifting from electric hot water vs gas hot water to a modern, efficient option can noticeably reduce overall bills.
Average annual bill savings in Rheola can look like this:
• Old electric to heat pump hot water installation: $450–$900 per year • Gas to heat pump hot water: $350–$750 per year • Gas to solar hot water installation: $300–$700 per year • Old electric to modern electric hot water installation powered by rooftop solar: $250–$600 per year
Brands like Rheem heat pump hot water, Sanden heat pump and EvoHeat are popular where efficiency is the priority, while Rheem solar hot water, Rinnai solar hot water and Chromagen solar hot water are common choices for a roof‑mounted solar hot water system.

Hot Water Rebates, Tariffs & Savings
Across Rheola there is growing interest in replacing old gas or electric units with efficient options like a heat pump hot water system, a modern electric hot water system or a solar hot water heating system. Federal incentives such as Small‑scale Technology Certificates (STCs) can reduce the solar hot water price / cost or heat pump hot water price / cost at the point of sale, while Victorian hot water rebate VIC programs often add a separate heat pump hot water rebate or solar hot water rebate for eligible homes. There are also electric hot water system rebate options in some schemes, particularly when moving away from gas.
For many Rheola households, these discounts can effectively reduce system cost by 30–50%, bringing the hot water system price / cost of a quality Rheem solar hot water or Sanden heat pump closer to a standard electric unit. Combine rebates with rooftop solar, timers or solar diversion, and payback periods can drop to just a few years, especially when comparing heat pump vs solar hot water or solar hot water vs electric hot water on lifetime running costs. Ongoing hot water repair and solar hot water repair support is available locally, along with solar hot water tank replacement when older cylinders finally fail.
