Hot water systems in Changerup
Around Changerup, more households are rethinking their hot water system and moving to energy efficient options like a heat pump hot water system, solar hot water system or modern electric hot water system. With most of the 190 local dwellings being separate houses and an average household size of 2.3 people, hot water demand is steady year‑round, especially for families and the many over‑50s in the area. Power prices keep rising, so upgrading from an older gas or electric unit to an energy efficient hot water system is a logical next step.
Changerup’s sunshine also does a lot of the heavy lifting. The nearby Riverdale weather station records an average annual solar exposure of 17.8 MJ/m² per day – roughly 4.9 kWh/m²/day – which is excellent for both a solar hot water heating system and for running a heat pump hot water system efficiently.

Installations were just a trickle in the early 2000s, with one or two systems in 2003, 2005, 2008 and 2011–2013.

This steady rise reflects a broader local shift towards electrification, lower running costs and more efficient hot water WA‑wide.
For many households here, the big question is heat pump vs solar hot water, or even solar hot water vs electric hot water. A quality heat pump hot water system can be the most efficient hot water system for shaded blocks or homes without ideal roof space. A solar hot water system with a well‑sized solar hot water tank replacement can be brilliant on the sunnier, more open properties around Changerup. Modern electric hot water installation can also make sense when paired with rooftop PV, especially for those using timers or solar diversion to heat water during the middle of the day.
