Where the money goes
Estimated breakdown for your configuration
An undersized heater never quite gets the pool warm and runs constantly. Size it to the pool and your climate, and always pair it with a blanket to keep the heat in.
Ways to save
- A pool blanket lets you run a smaller, cheaper heater and slashes running cost.
- Heat pumps cost more upfront than gas but far less to run for regular use.
How we estimate this
Most Australian pools need a 9kW to 18kW heater in 2026, costing roughly $3,000 to $12,000 supplied and installed depending on pool size and heater type. Bigger pools and year-round use need more output.

What a pool heater size costs in Newcastle
A pool heater in Newcastle is sized from the pool's surface area and volume, the temperature rise wanted above the ambient, and whether a cover is fitted, since most heat escapes from the surface, so a larger pool and a bigger desired rise call for a bigger heater, and a cover cuts the loss. The heater type is the big choice: gas heats fast, a heat pump is cheaper to run regularly, and solar is cheapest but weather-dependent. The labour advantage helps, as rates sit below Sydney's while drawing on the same Hunter trade pool, so the install is better value than in the capital.
The coastal, temperate climate around Newcastle suits a heat pump or solar to extend the swimming season into the cooler months, as the winters are milder than inland. A cover holds heat overnight and cuts evaporation in the coastal wind. An older workers' cottage with a newer pool is a common install. The industrial heritage gives a deep pool of installers, so the work is well resourced and keenly priced below Sydney's. Near the water the unit is specified to resist the salt air. A gas heater is connected by a licensed gas fitter, a heat pump by a licensed electrician with a refrigeration technician, and solar by an accredited installer, in New South Wales.
A pool heater is sized by the pool and the climate, and installed by the relevant licensed trade — a licensed gas fitter for a gas heater, a licensed electrician and refrigeration technician for a heat pump, or an accredited installer for solar, in New South Wales under NSW Fair Trading. For a Newcastle pool, the clearest way to size a heater is by the surface area and volume, the temperature rise wanted, and whether a cover is used, at better value than Sydney.
