How to choose here

  • Licensed plumber or gasfitter. Installing or replacing a hot water system is licensed plumbing work in NSW — and gas systems need a gas licence. Confirm it at NSW Fair Trading.
  • Match the system to your home. Heat pump and solar cost more upfront but cut running costs; gas continuous-flow suits larger households; electric storage is cheapest to install. Ask for advice.
  • Rebates. Heat pump and solar systems may attract NSW or federal rebates — ask what is currently available.
  • Emergencies. Ask about after-hours rates and how quickly they can replace a failed unit.

FAQ

  • Repair or replace? A leaking tank usually means replacement; element or valve faults can often be repaired. A specialist will advise.
  • Which system is cheapest to run? Generally heat pump or solar, then gas, then electric storage — but it depends on your usage and rates.
  • Free to contact? Yes — you deal with the specialist directly.
