Palmerston’s mean daily solar exposure sits around 17.3 MJ/m², or roughly 4.8 kWh/m² per day across the year, which is excellent for both a solar hot water heating system and a modern heat pump hot water system that draws most of its energy from the air.
With a high share of separate houses (over 9,000 dwellings) and strong home ownership – more than 9,500 homes owned outright or with a mortgage – many Palmerston homeowners are in a good position to invest in long-term savings. A modern hot water installation, whether it’s heat pump, solar or electric, can significantly reduce annual hot water energy use while improving comfort. Brands like Rheem heat pump hot water, Rheem solar hot water, Rinnai solar hot water and premium units such as a Sanden heat pump are all popular choices when comparing the best hot water system Australia has to offer.
In Palmerston 2913, efficient hot water upgrades are typically sized around the needs of a 3–4 bedroom family home, where hot water demand is steady year-round. As more rooftops add solar, pairing an electric hot water system or heat pump with daytime solar generation is becoming the most efficient hot water system option for many households. When people compare heat pump vs solar hot water or solar hot water vs electric hot water, they are usually weighing upfront hot water system price or cost against running costs and roof space.
Typical bill savings from a hot water upgrade in Palmerston can look like:
• Old electric to heat pump hot water installation: save around $350–$700 a year. • Gas to heat pump hot water system: save roughly $250–$600 a year. • Gas to solar hot water installation: save about $200–$550 a year. • Old electric to modern electric hot water installation with rooftop solar: save around $250–$600 a year.
Local installers regularly work with well-known brands like Chromagen solar hot water, Rheem, Rinnai and Sanden to match systems to family size, roof orientation and budget. When comparing heat pump hot water price or cost and solar hot water price or cost, it is important to factor in rebates, tariffs and future energy prices, not just the sticker price.

Installations climbed sharply around 2008–2011, with a peak of 45 systems in 2009 and strong years in 2010 and 2011, then steady numbers through the mid‑2010s and ongoing installs through to 2025. This trend reflects growing local interest in electrification, lower running costs and moving away from older gas hot water. Each hot water repair or solar hot water tank replacement is now a chance to switch to a more efficient technology instead of simply replacing like-for-like.
Hot Water Rebates, Tariffs & Savings
Across Palmerston ACT, more residents are replacing ageing gas or electric units with efficient options such as a heat pump hot water system, a newer electric hot water system or a roof-mounted solar hot water system. Federal incentives like Small-scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively providing a discount off the upfront hot water system price or cost. On top of that, ACT and other state-based programmes periodically offer a solar hot water rebate, heat pump hot water rebate or electric hot water system rebate that can reduce the cost of going efficient by a substantial percentage.
For many Palmerston homes, these hot water rebate ACT incentives can trim thousands off the installed cost, shrinking payback periods to just a few years. Typical savings from an efficient hot water upgrade can easily reach hundreds of dollars per year, especially when combined with rooftop solar and smart controls. Using timers or solar-diversion to run a heat pump or electric hot water system during the middle of the day helps squeeze even more value from your panels and turns your cylinder into a thermal battery. That is why many locals now see an energy efficient hot water system as a key step towards an all-electric home and lower long-term bills.
