Hot water systems in Mount Rumney
Across Mount Rumney and the wider 7170 area, more households are starting to look closely at their hot water system and what it is costing them. With most of the 1,976 dwellings here being separate houses and an average household size of 2.8 people, hot water demand is steady all year round. Power prices are front of mind, especially for families with a median household income of around $2,326 a week and a decent chunk of that going on mortgages and everyday expenses. Upgrading from an older gas or electric hot water system to a modern heat pump hot water system, solar hot water system or efficient electric hot water system is becoming a logical next step.
Mount Rumney’s own weather station records an average annual solar exposure of about 13.9 MJ/m² per day – roughly 3.9 kWh/m²/day – which is solid for both a solar hot water heating system and for helping a heat pump hot water system run efficiently. When you combine that with the high level of home ownership (over 1,700 homes owned outright or with a mortgage), it makes sense that locals are investing in long‑term energy efficient hot water system upgrades that can deliver strong Annual Hot Water Energy Savings over the life of the unit.
In the 7170 postcode there have already been 135 efficient hot water installations, mainly heat pump and solar hot water installation jobs. Installations really took off around 2009–2011, with peaks of 18, 17 and 30 systems per year, showing how quickly interest grew once people saw real bill savings. While recent years have been quieter, the foundations are there: more homes with solar, more talk about electrification, and a growing preference for the most efficient hot water system people can reasonably afford.
For a typical Mount Rumney household, hot water can be one of the biggest single energy users. Swapping out an old electric unit or gas storage system for a quality Rheem heat pump hot water, Sanden heat pump or a solar hot water system from brands like Rheem solar hot water or Chromagen solar hot water can make a real dent in running costs. Rinnai solar hot water is also popular for those wanting a reliable solar hot water tank replacement or a fresh solar hot water installation that pairs neatly with existing rooftop solar. For others, a modern electric hot water installation, timed to run on solar during the day, can be a smart middle ground when comparing solar hot water vs electric hot water.
Typical annual bill savings for Mount Rumney homes can look like this:
• Old electric to heat pump hot water system: save roughly $350–$700 per year • Gas to heat pump hot water system: save around $300–$600 per year • Gas to solar hot water system: save about $250–$550 per year • Old electric to modern electric hot water installation with solar: save roughly $200–$450 per year
When people ask about heat pump vs solar hot water, the answer often comes down to roof space, budget and how you use power. Heat pumps such as Sanden heat pump units tend to win on flexibility and very low running costs, while a well‑designed solar hot water heating system can be brilliant if you have good north‑facing roof and want to maximise free sun. Either way, brands like Rheem solar hot water and Rinnai solar hot water sit comfortably among the best hot water system Australia has to offer, and there are some excellent contenders for the best heat pump hot water system too.
Hot Water Rebates, Tariffs & Savings
Around Mount Rumney, more homeowners are quietly planning to move away from gas and older resistive units towards efficient options like heat pump hot water installation, solar hot water repair and upgrade work, or a new electric hot water system with smart controls. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems Tasmania‑wide, effectively acting as an upfront discount. On top of that, state‑based heat pump hot water rebate and solar hot water rebate programs, plus an electric hot water system rebate in some schemes, can significantly cut the overall hot water system price or cost. For many homes, these hot water rebate TAS incentives mean the heat pump hot water price or cost and solar hot water price or cost can be reduced by a substantial percentage, shaving years off the payback period. Combine that with timers, smart tariffs and solar diversion, and you can turn an already energy efficient hot water system into one of the lowest‑cost, lowest‑emission appliances in the home.
If your current unit is more than 10 years old, running on gas, or you are noticing more frequent hot water repair call‑outs, it may be time to compare electric hot water vs gas hot water and explore a proper upgrade.
