Estimated breakdown for your configuration
Heat pumps cost more upfront but run on a fraction of the energy of electric storage, and government rebates can cut the net price significantly, ask your installer.
A like-for-like swap is cheapest and fastest. Rebates and the much lower running cost of heat pump and solar can make the dearer options cheaper over their life.
Ways to save
- Check federal and state rebates for heat pump and solar hot water, they can cut the upfront cost substantially.
- A like-for-like replacement on the existing connection is the cheapest job.

What a hot water system replacement costs in Hobart
A hot water system replacement in Hobart is priced mainly by the system type and capacity, with an electric storage tank cheapest to install, a heat pump a step up, and a solar system the premium up-front option, while gas is less common given Tasmania's limited mains-gas network. The small Tasmanian market with limited competition keeps the install firm, and a specialist unit can carry island freight. A like-for-like swap is the cheapest path.
Hobart's cold climate and Tasmania's cheap, largely hydro-powered electricity shape the choice, because with gas scarce and power comparatively cheap, electric storage and heat pumps are the common systems, and the cold means the unit is sized larger for the heavy hot water use of a long winter. A heat pump in Hobart's cold needs to be a cold-climate-rated model, as a basic air-source unit loses efficiency on frosty mornings, and an outdoor unit and pipes must be lagged against the frost. Solar hot water works but the shorter, cooler winter days generate less, so it usually needs an electric boost. The colonial and heritage homes can make routing a changeover awkward. Where gas is used it is often bottled LPG.
A hot water system must be installed by a licensed plumber in Tasmania, with a licensed gas fitter for a gas unit and a licensed electrician for an electric or heat pump unit, with licensing under the state regulators rather than Tasmanian occupational building licensing. For a Hobart home, the clearest way to price a hot water system replacement is by the system type, with electric and cold-climate heat pump favoured and island freight a factor.

Frequently asked questions
Which hot water system suits Hobart?
Electric storage and heat pumps, because Tasmania's mains gas is scarce and the largely hydro-powered electricity is comparatively cheap, so these are the common systems, with the cold sizing the unit larger for a long winter's heavy hot water use in Hobart.
Does a heat pump work in Hobart's cold?
With the right model. A basic air-source heat pump loses efficiency on frosty mornings, so a Hobart home needs a cold-climate-rated model, and an outdoor unit and pipes must be lagged against the frost to protect them.
Does island freight affect a hot water replacement in Hobart?
It can. The small Tasmanian market with limited competition keeps the install firm, and a specialist unit can carry island freight, adding lead time to a Hobart hot water replacement compared with the mainland.
Do I need a licence to replace a hot water system in Hobart?
Yes. A hot water system must be installed by a licensed plumber in Tasmania, with a licensed gas fitter for a gas unit and a licensed electrician for an electric or heat pump unit, with licensing under the state regulators rather than Tasmanian occupational building licensing.
