Hot water systems in Longley
Around Longley and the 7150 area, more locals are rethinking their old gas and electric hot water system and switching to energy‑efficient options. With most homes here being separate houses and an average household size of about 2.4 people, hot showers, dishwashers and washing machines add up. Power bills can bite, especially for families and older residents on fixed incomes, so upgrading to a modern heat pump hot water system, solar hot water system or efficient electric hot water system is becoming a smart next step.
Longley’s climate is actually well suited to efficient hot water. The local solar exposure averages about 13.2 MJ/m² per day over the year, which works out to roughly 3.7 kWh of solar energy per square metre, per day. That is plenty of sunlight to support a solar hot water heating system and to help a heat pump hot water system run efficiently, especially when paired with rooftop solar. With around 1,224 occupied private dwellings and a median household income that supports long‑term investments, many owners are looking for the most efficient hot water system they can reasonably afford, rather than just the cheapest replacement.
Across the 7150 postcode there have already been 111 efficient hot water installations, including heat pump hot water installation and solar hot water installation. Installations really picked up from 2009 to 2012, with peak years in 2009, 2010 and 2011, and there is renewed interest again with new systems going in during 2024 and 2025. That steady trend shows more Longley households are moving towards electrification, lower running costs and a more energy efficient hot water system instead of sticking with old gas or resistive electric units.
For a typical Longley home, hot water can be one of the biggest single energy loads. Swapping to a quality heat pump or solar hot water system can trim a big chunk off your usage. Rough annual bill savings can look like this:
• Old electric to heat pump hot water system: save about $450–$900 per year • Gas to heat pump hot water system: save about $300–$700 per year • Gas to solar hot water system: save about $250–$650 per year • Old electric to modern electric hot water installation with solar: save about $250–$600 per year
Brands like Rheem, Rinnai, Sanden and Thermann are common choices in Tasmania. Rheem solar hot water and Rinnai solar hot water are popular when roof space and aspect are good, while Rheem heat pump hot water and the premium Sanden heat pump units are often picked for colder‑climate efficiency. Thermann heat pumps are another solid option for those chasing the best heat pump hot water system for value. If you already have panels, using a smart controller to run an electric hot water system on solar can also work well, and many locals compare heat pump vs solar hot water or solar hot water vs electric hot water to see which suits their roof, budget and lifestyle.
Of course, every upgrade has a hot water system price to consider. A basic electric hot water installation is usually cheaper upfront, but the long‑term running costs are much higher. Heat pump hot water price ranges are higher to begin with, but with today’s rebates and lower power use, the payback can be surprisingly quick. The same goes for solar hot water price ranges: a solar hot water heating system costs more upfront than a straight electric unit, but with Longley’s decent solar exposure and the right tariff, it can pay for itself over time. When a system gets older, solar hot water tank replacement, hot water repair or full hot water installation are all on the table, and it is worth running the numbers.
Hot Water Rebates, Tariffs & Savings
In Tasmania there is growing interest in replacing tired gas or electric units with efficient options like heat pumps, modern electric hot water and solar hot water. For Longley homeowners, federal incentives such as Small‑scale Technology Certificates (STCs) can reduce the effective solar hot water price or heat pump hot water cost at the point of sale. On top of that, state‑based programs and retailer offers can act like a solar hot water rebate, heat pump hot water rebate or even an electric hot water system rebate in some cases, cutting the upfront cost by a substantial percentage. When you combine a good hot water rebate tas with off‑peak tariffs or solar‑diversion controls, payback periods can shorten to just a few years, especially if you are moving from electric hot water vs gas hot water to a much more efficient setup.
If your current system is leaking, more than 10 years old, or costing a fortune to run, it is a good time to check whether your Longley home is ready for a hot water upgrade. Whether you are weighing up heat pump vs solar hot water, looking at rheem solar hot water or chromagen solar hot water, or simply need reliable hot water repair, working with experienced local hot water tas installers matters. With Longley’s strong interest in sustainability and solid solar resource, an efficient hot water system can cut bills, reduce emissions and future‑proof your home.
