Hot water systems in Narran Lake
Across Narran Lake and the wider 2839 area, more households are starting to look closely at their hot water system and what it costs to run. With average household sizes around 2.3 people and many separate houses on larger blocks, hot water demand is steady, but budgets are tight, with median household income just over $1,000 a week. That makes upgrading from old gas or power‑hungry electric units to an energy efficient hot water system a smart, long‑term move.
Narran Lake is blessed with serious sunshine. The local weather station records mean daily solar exposure of about 19.8 MJ/m², or roughly 5.5 kWh/m² per day over the year – even more in summer. That strong solar resource supports both a solar hot water system and a modern heat pump hot water system, especially when paired with rooftop solar. For many homes, hot water makes up a big slice of power use, so cutting that back delivers some of the best Annual Hot Water Energy Savings available.
With 371 occupied private dwellings, a big share of which are rented or public housing, people are often chasing reliability and low running costs rather than fancy gear. But efficient technology is becoming the norm. In Narran Lake, efficient hot water installation numbers are still modest, yet growing – hot water data shows 10 heat pump and solar hot water installations in total, with early interest around 2009–2014 and a fresh jump in 2025. That recent lift reflects rising power prices, interest in electrification and the appeal of moving away from gas hot water.
For a typical Narran Lake home, a heat pump hot water system or solar hot water heating system is usually sized around 200–300 litres for smaller households, and 300–400 litres for families. Many locals are comparing heat pump vs solar hot water, as well as solar hot water vs electric hot water, to see what stacks up best. As a guide, realistic annual bill savings can look like:
• Old electric to heat pump hot water system: save around $350–$700 per year • Gas to heat pump hot water system: save around $250–$600 per year • Gas to solar hot water system: save around $200–$550 per year • Old electric to modern electric hot water system with rooftop solar: save around $250–$500 per year
Brands like Rheem heat pump hot water and Rheem solar hot water are common choices for reliable, mainstream systems, while Sanden heat pump units are popular for premium efficiency and very low running costs.
