Choosing a Hot Water System in Grafton (2026 Guide)
The right hot water system depends on your household size, energy costs and whether your Grafton property runs on mains gas, LPG or electric only. Here's how to choose.
Grafton's climate is ideal for heat pumps
The Clarence Valley's mild winters and warm daytime temperatures make heat pump hot water systems one of the most efficient options available. Modern units draw ambient heat from the air and use roughly a third of the electricity of a traditional storage electric system — a genuine long-term saving that pairs well with rooftop solar.
Gas vs electric — what makes sense in the Valley
Central Grafton has mains natural gas in many streets, while outer suburbs and rural properties rely on LPG bottles. Continuous flow gas systems are excellent for large families because they never run out of hot water; storage electric units remain the cheapest to install and suit smaller households. We'll assess your energy supply and usage before recommending an option.
Sizing your system correctly
As a rough guide: 1-2 people need 125-160L storage or 16L/min continuous flow; 3-4 people need 250-315L storage or 20-26L/min continuous flow; 5+ people need 400L+ storage or 32L/min continuous flow. Undersizing is the #1 complaint we hear — and the fix is almost always a full replacement, so it's worth getting right at the start.
Rebates and installation
NSW households can access federal STC rebates and state energy incentives for eligible heat pump and solar hot water installations, often bringing the up-front cost close to a like-for-like electric replacement. We handle the paperwork, install to Australian Standards, and provide compliance certification on completion.
