Hot water systems in Lonnavale
Across Lonnavale and the 7109 postcode, more households are rethinking their old gas and electric hot water system and shifting to efficient options like a heat pump hot water system, solar hot water system and modern electric hot water system. With an average household size of around 2.5 people and more than 3,600 dwellings in the area, reliable hot water is essential – but so is keeping running costs under control.
The local climate actually suits efficient hot water technology better than many people realise. The nearby Denison River weather station records mean daily solar exposure of about 13.1 MJ/m², which works out to roughly 3.6 kWh/m² per day over the year. That level of sunlight supports both a solar hot water heating system and a high‑quality heat pump hot water system, especially when combined with rooftop solar. For Lonnavale homeowners juggling median mortgage repayments of about $1,430 a month and a median household income of $1,397 a week, cutting hot water energy use can make a real difference to the budget.
In 7109, most homes are separate houses, and many families and retirees are living in three‑ and four‑bedroom places, so hot water demand can be significant. Hot water typically accounts for 20–30% of a home’s energy use, so upgrading to an energy efficient hot water system is often the easiest way to shrink bills. Modern options range from rheem heat pump hot water and sanden heat pump units through to rinnai solar hot water and chromagen solar hot water systems, along with efficient electric hot water installation paired with rooftop solar.
When you look at system sizes and savings for a typical Lonnavale home, the numbers stack up well. A well‑sized heat pump hot water installation can use a fraction of the electricity of an old electric storage unit, and a good solar hot water installation with a solar hot water tank replacement can take care of most of your hot water needs from the sun. Here are some realistic average annual bill savings for local upgrade scenarios:
• Old electric to heat pump hot water system: $350–$700 per year • Gas to heat pump hot water: $300–$650 per year • Gas to solar hot water system: $250–$600 per year • Old electric to modern electric hot water with rooftop solar: $250–$550 per year
Brands like Rheem and Rinnai remain popular in the area for both rheem solar hot water and rinnai solar hot water packages, while premium options such as a sanden heat pump are often chosen by households chasing the most efficient hot water system on the market. For many, the best hot water system Australia can offer is one that balances upfront hot water system price / cost with low running bills and strong warranties. Comparing heat pump vs solar hot water, and even solar hot water vs electric hot water, is a smart step before you commit.
Efficient systems are already making an impact locally. There have been 219 efficient hot water installations – mainly heat pump and solar hot water – recorded across the 7109 postcode. Installations really took off around 2009 and 2010, with 25 and 55 systems installed in those years alone, then continued at a steady pace through the 2010s. Even in recent years, Lonnavale has seen ongoing activity, with new systems going in every year through to 2025. This trend shows growing interest in electrification, lower running costs and cleaner hot water tas solutions.
Hot Water Rebates, Tariffs & Savings
Across Lonnavale, more people are replacing old gas or ageing electric units with a heat pump hot water system, a solar hot water system or a modern electric hot water system that works neatly with rooftop solar. A big driver is the range of Australian Government incentives that bring the heat pump hot water price / cost and solar hot water price / cost down to something much more affordable.
Most efficient systems are eligible for Small‑scale Technology Certificates (STCs), which effectively act as an upfront discount on your hot water installation. On top of that, Tasmania’s state‑based programs and retailer offers can operate like a solar hot water rebate, heat pump hot water rebate or even an electric hot water system rebate for certain high‑efficiency models. For many Lonnavale households, these hot water rebate tas incentives can knock a substantial percentage off the initial cost, trimming payback periods to just a few years.
Once installed, an energy efficient hot water system can save hundreds of dollars a year. Combine a heat pump or solar hot water heating system with rooftop solar, off‑peak tariffs, timers or solar diversion, and you can push those savings even further while reducing your reliance on gas. For some families, carefully set controls turn their system into the best heat pump hot water system for their lifestyle, heating water when solar output is highest and cutting grid imports.
If your current unit is getting old, running out of hot water, or your bills are creeping up, it may be time to check whether your Lonnavale home is ready for a hot water upgrade. Whether you are weighing up electric hot water vs gas hot water, comparing heat pump vs solar hot water, or planning a solar hot water repair or solar hot water tank replacement, working with experienced hot water repair and installation specialists matters.
