Hot water systems in Hmas Harman
Across HMAS Harman and the 2600 postcode, more locals are swapping old gas and ageing electric units for an energy efficient hot water system that keeps bills down and showers steaming. With an average household size of 2.2 people and many three‑ and four‑bedroom homes, hot water demand is steady, and so are the running costs if you stay on old technology. Median household incomes are solid, but with mortgages around $2,819 a month and rents near $540 a week, no one wants to waste money on an inefficient hot water system.
The local climate helps. The nearby Queanbeyan station records about 17.1 MJ of solar energy per square metre per day on average – roughly 4.75 kWh/m²/day – which is excellent for both a solar hot water system and a modern heat pump hot water system. That strong solar exposure means a solar hot water heating system can do much of the work for free, while a heat pump hot water system uses the mild ACT air to pull heat into the tank using far less electricity than an old electric hot water system.
In HMAS Harman and surrounds, there is a mix of separate houses and over 1,100 flats and apartments, so hot water installation needs to be matched carefully to roof space, access and tariffs.
