Choosing a Hot Water System in Orange

The Four Types of Hot Water Systems

Electric storage: Heat water with an electric element and store it in an insulated tank. Most common and simplest to install. Most expensive to run on standard tariffs. Suitable for all locations.

Gas instantaneous: Heat water on demand. Efficient (no standby heat loss), unlimited supply. Requires a gas connection. Best option for most Orange homes with town gas.

Solar hot water: Solar collectors on the roof heat water, with electric or gas booster. Lowest running cost. Highest upfront cost. Government rebates available. Requires suitable north-facing roof space.

Heat pump: Uses refrigerant technology (like a reverse-cycle air conditioner) to heat water very efficiently. 3–4× more efficient than electric storage. Government rebates available. Performs best in ambient temperatures above 5°C — Orange's cold winters require consideration.

Orange's Climate and Hot Water

Orange sits at 900 metres elevation, giving it cold winters and significant temperature swings that cause pipe expansion and contraction throughout the year.

Heat pumps work by extracting heat from ambient air. In Orange's coldest winter months, ambient temperatures can limit heat pump efficiency. Modern heat pumps operate down to -5°C, but performance declines below about 5°C. If your property is in an exposed location in Bowen or Calare, discuss this with your plumber before committing to a heat pump.

Solar hot water suits Orange's climate well — the cooler, clearer days provide good solar resource, and a gas or electric booster handles the cold winter days when solar collection is insufficient.

Government Rebates in Orange

The federal Small-scale Technology Certificate (STC) scheme provides rebates on solar hot water and heat pump systems. The rebate is calculated based on system type and your postcode — for Orange (postcode 2800), typical STC values run $600–$1,500 for solar and $300–$800 for heat pump systems. We calculate and apply this rebate as a discount on your invoice.

Note: STCs are only claimable through licensed plumbers installing eligible systems — another reason to ensure the person installing your hot water is actually licensed.
