How much does a hot water system cost in Hobart?
A hot water system in Hobart costs $720–$2,700 for electric storage, $1,075–$3,150 for gas storage, $1,350–$3,150 for continuous flow gas, and $2,700–$5,400 for a heat pump (before rebates). Government incentives can reduce heat pump costs — the federal Small-scale Renewable Energy Scheme applies in every state, and your state may offer its own rebate on top.

Replacing a hot water cylinder in Hobart, line by line
A like-for-like electric cylinder swap in Hobart
An electric storage cylinder, supplied and installed, is $720–$2,700 in our Hobart table. Taking the old one away is $68–$180 and a tempering valve, where the install needs one, $135–$360; the three come to $1,965 at the typical prices.
When a Hobart cylinder fails without warning
An emergency replacement is $1,175–$3,600 installed in our Hobart table, against a typical $1,625 for a planned electric swap. Replacing the anode is $180–$450 a job.
A heat pump instead of another electric cylinder in Hobart
After rebates, a heat pump is $2,250–$4,775 installed in our Hobart table, $1,625 more than an electric cylinder at the typical prices. The same table puts the running cost of an electric system at $450–$1,075 a year.

What Affects Hot Water System Costs in Hobart
System type
Electric storage is cheapest upfront ($720–$2,700 in Hobart) but among the dearest to run. Heat pumps ($2,700–$5,400) cost more upfront but use far less electricity to heat the same water.
Household size
A family of 4 in Hobart typically needs a 250–315L storage system or a 26L/min continuous flow unit. Undersizing means running out of hot water; oversizing wastes energy.
Government rebates
Government incentives can reduce heat pump costs — the federal Small-scale Renewable Energy Scheme applies nationally. Tasmania's Energy Saver Loan Scheme, which offered interest-free loans of up to $10,000 that could be used for heat pump and solar hot water systems, closed on 1 September 2025 and takes no new applications. Check energy.gov.au for current eligibility — rebates change frequently.
Existing infrastructure
Replacing like-for-like (electric for electric, gas for gas) in Hobart is cheapest. Switching fuel types may require new gas lines, electrical work, or plumbing modifications.
Location of unit
Indoor vs outdoor, roof vs ground — relocating a hot water system in your Hobart home adds plumbing and electrical work, so have it priced on the quote.
Emergency vs planned
Emergency replacement in Hobart usually costs more than planned — you have less time to compare quotes and may need after-hours installation.
Gas hot water in Hobart — storage, continuous flow and the LPG question
Gas hot water in Hobart costs $1,075–$3,150 installed for a storage system and $1,350–$3,150 for a continuous flow unit. The catch is supply: Hobart’s reticulated natural gas network only reaches some suburbs, so many homes run gas hot water on bottled LPG instead — fine for continuous flow units, but bottle rental and refills add to the yearly running cost.
Because Tasmania’s electricity is comparatively cheap, gas hot water does not get the same running-cost edge in Hobart that it does on the mainland. See the gas vs electric running cost guide and the continuous flow cost breakdown before choosing gas over a heat pump.
How to Save Money on Hot Water System Cost in Hobart
Gas hot water in Hobart
Gas hot water in Hobart comes with a Tasmanian twist: reticulated natural gas only reaches some suburbs, so plenty of Hobart homes run gas hot water on bottled LPG instead. System prices are the same either way — gas storage runs $1,075–$3,150 installed (typically $1,975) and continuous flow gas $1,350–$3,150 — but LPG adds bottle rental and higher running costs, which is worth weighing before you commit.
- On natural gas (CBD and inner suburbs on the network): continuous flow is compact, efficient and never runs cold
- On LPG: continuous flow still works well, but compare running costs against a heat pump first — after federal STC rebates a heat pump lands at $2,250–$4,775 installed and costs far less to run
- Like-for-like gas replacement is usually same-day; switching fuel types adds electrical or gas-fitting work to the quote
