Hot water systems in Carlton
Across Carlton, more owners and body corporates are rethinking their old gas and electric hot water system and shifting to energy efficient options like a heat pump hot water system, solar hot water system and modern electric hot water system. With a young population, lots of apartments and townhouses, and rising energy costs, it makes sense to upgrade to the most efficient hot water system you can reasonably fit into your property.
Carlton’s average household size is only 1.8 people, with a big share of residents renting and many smaller dwellings and student apartments. That means hot water demand is steady but not huge, so a well sized energy efficient hot water system can cover daily needs without wasting power. The local median household income sits around $1,291 per week, so reducing ongoing power bills matters just as much as the upfront hot water system price or cost. On the climate side, Melbourne’s mean daily solar exposure sits around 15.10 MJ/m², or roughly 4.2 kWh/m² per day, which is strong enough to support both a quality solar hot water heating system and a high performance heat pump hot water system. When you replace old gas or resistive electric hot water with a modern system, annual hot water energy savings in Carlton can easily run into the hundreds of dollars.
Looking at system sizes and savings for 3053, most homes are one‑ or two‑bedroom units or flats, so compact heat pump hot water installation or wall‑mounted electric hot water installation is often the most practical option, with solar hot water installation suited to townhouses and roof spaces with good access. Brands like Rheem heat pump hot water, Sanden heat pump and EvoHeat are popular where owners want the best heat pump hot water system with very low running costs, while Rheem solar hot water and Rinnai solar hot water are common choices for a roof‑mounted solar hot water system. For many, the decision comes down to heat pump vs solar hot water, or solar hot water vs electric hot water if roof space is tight.
Typical annual bill savings in Carlton for a well designed upgrade look like:
• Old electric to heat pump hot water system: save about $350–$700 per year. • Gas to heat pump hot water: save around $250–$600 per year. • Gas to solar hot water heating system: save roughly $200–$550 per year. • Old electric to modern electric hot water with rooftop solar: save about $250–$500 per year.
Recent installs in Carlton show how interest in hot water VIC upgrades has grown over time. There have been 50 efficient hot water installations recorded in the postcode, combining both heat pump and solar hot water installation. After only a handful of systems each year in the early 2000s, installations jumped to a peak of 19 in 2015, with steady but smaller numbers in surrounding years. This pattern reflects the broader push towards electrification, better hot water repair and replacement decisions, and lower running costs in inner‑city suburbs. Many owners now look at hot water system price or cost over the full life of the unit, not just the sticker price, and factor in future hot water repair, solar hot water tank replacement, and the impact of choosing electric hot water vs gas hot water.
Hot Water Rebates, Tariffs & Savings
Around Carlton, there is growing interest in swapping out old gas storage units for a heat pump hot water system or efficient electric hot water system that can run on solar. Homeowners can often access a mix of Australian Government Small‑scale Technology Certificates (STCs) and Victorian energy efficiency incentives that effectively act as a solar hot water rebate, heat pump hot water rebate or electric hot water system rebate.
