With an average household size of 2.5 people and more than 3,600 occupied dwellings, reliable hot water is a big part of everyday life here – and a big chunk of power bills. Median household income sits around $1,397 a week, so when energy prices rise, it is no surprise locals start looking for the most efficient hot water system they can reasonably afford.
Grove’s climate is actually well suited to efficient hot water upgrades. The local weather station records mean daily solar exposure of about 13.2 MJ/m², which works out to roughly 3.7 kWh of solar energy per square metre per day over the year – plenty to support a quality solar hot water heating system or to help a heat pump hot water system run efficiently. With many homes already using rooftop solar, upgrading from older gas or resistive electric units to an energy efficient hot water system is a logical next step, with annual hot water energy savings often reaching hundreds of dollars per home.
In the 7109 postcode, most dwellings are separate houses with three or more bedrooms, which usually means higher hot water demand from families and multi‑generation households. That makes the choice between heat pump vs solar hot water, or solar hot water vs electric hot water, an important one. Brands like Rheem heat pump hot water and Rheem solar hot water are popular for all‑round reliability, while Sanden heat pump units are known for ultra‑high efficiency and very low running costs. Rinnai solar hot water and Chromagen solar hot water systems also appear regularly in local hot water installation work, especially where homeowners want to pair a solar hot water tank replacement with existing PV.
Average annual bill savings in Grove will vary by house size and tariffs, but typical ranges look like:
• Upgrading old electric to a heat pump hot water system: $400–$900 a year • Switching gas to heat pump: $300–$800 a year • Switching gas to a solar hot water system: $250–$700 a year • Replacing old electric with a modern electric hot water system plus rooftop solar: $250–$600 a year
Recent data shows 219 efficient hot water systems have already been installed in the Grove area, including both heat pump hot water installation and solar hot water installation projects. Installations climbed sharply around 2009–2011, peaking at 55 systems in 2010 as rebates and interest in the best hot water system Australia could offer really kicked in. While yearly numbers have eased since, there is a steady trickle of new systems from 2016 onwards, reflecting ongoing interest in electrification, lower running costs and hot water repair or replacement before older units fail.
Hot Water Rebates, Tariffs & Savings
For hot water TAS homeowners, there is growing interest in replacing old gas or electric units with efficient options like heat pumps, modern electric hot water installation, or a solar hot water installation. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pump units, effectively acting as an upfront discount off the solar hot water price / cost or heat pump hot water price / cost. On top of that, state‑based hot water rebate TAS programs often include a heat pump hot water rebate, solar hot water rebate and, at times, an electric hot water system rebate for high‑efficiency models. These can reduce the overall hot water system price / cost by a substantial percentage and shorten payback to just a few years, especially if you use timers or solar diversion to run the system when your PV is generating.
Whether you are comparing electric hot water vs gas hot water, weighing up heat pump vs solar hot water, or just need urgent solar hot water repair or general hot water repair, it pays to get local advice. Grove’s strong solar resource and growing interest in sustainability mean efficient hot water upgrades can cut bills, reduce emissions and future‑proof your home.
