Hot water systems in Knuckey Lagoon
In Knuckey Lagoon, more locals are swapping old gas and ageing electric units for modern, energy efficient hot water systems that suit our climate and lifestyle.

Upgrading to a heat pump hot water system, solar hot water system or modern electric hot water system is a logical next step for households looking to cut bills and future‑proof their property.
Our tropical NT sun is a huge advantage. The Berrimah Research Farm records mean daily solar exposure of about 21.2 MJ/m², which is roughly 5.9 kWh/m² per day. That strong sunlight helps a solar hot water heating system perform brilliantly and also boosts efficiency when you pair a heat pump hot water system or electric hot water system with rooftop solar.

Installations rose from 23 in 2018 to over 50 systems a year from 2021 through 2024, showing real momentum towards electrification and lower running costs. This trend reflects growing interest in the most efficient hot water system options, and in moving from electric hot water vs gas hot water towards all‑electric, solar‑ready homes.
For many households, the big question is heat pump vs solar hot water. A quality heat pump hot water installation can work brilliantly in Knuckey Lagoon’s warm climate, using ambient air rather than roof collectors.

Either way, pairing systems with existing solar PV can make them an energy efficient hot water system that slashes bills. Typical solar hot water price or cost and heat pump hot water price or cost will vary by size and brand, but rebates and smart tariffs help a lot.
