Pool Heater Size in Hobart (2026)
In Hobart a pool heater is sized by the pool's area and volume, the temperature rise wanted, and the cover, with the cold climate making heating essential.
Your pool heater size details
Bigger pools need more heater output to reach temperature in reasonable time.
A pool blanket dramatically cuts heat loss, so you can run a smaller heater.

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 Hobart
A Hobart pool heater is scaled to how much water it must warm, how far above the ambient you want it, and whether a cover is used, since the surface loses most of the heat, so more water or a larger lift needs more capacity and a cover cuts the loss sharply. The type carries the rest — gas for a fast heat, a heat pump for cheap regular running, solar for the lowest running cost when sunny — so the water, the target and the type drive the Hobart sizing.
Hobart's cold climate makes heating essential for a usable pool, because without it the water is too cold for most of the year, so the heater is sized for a large temperature rise and a gas heater or a well-specified heat pump is often needed as the cold limits a basic heat pump. A cover is essential to hold heat through the frosty nights. The sloping sites mean the equipment is sited to suit the fall. Pools are less common here, and island freight can add to a specialty unit. 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 Tasmania.
The sizing comes from the pool and the climate, and the install goes to the right licensed trade: a licensed gas fitter on gas, a licensed electrician with a refrigeration technician on a heat pump, or an accredited installer on solar, in Tasmania under the state regulator on the building side. A Hobart heater is sized from the water surface and volume, the lift wanted and the cover, with the cold climate making heating essential for a usable pool.
