What Affects Hot Water System Costs in Hobart
System type
Electric storage is cheapest upfront ($720–$2,250 in Hobart) but most expensive to run. Heat pumps ($2,700–$5,400) cost more upfront but save $300–$500/year in running costs.
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
Federal and state rebates for heat pumps can reduce costs by $800–$1,000+ in Hobart. 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 costs $500–$2,000 extra in plumbing and electrical work.
Emergency vs planned
Emergency replacement in Hobart costs 10–20% 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–$2,700 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 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–$2,700 — 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 Tasmanian rebates a heat pump lands at $1,800–$4,500 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
