Storage and continuous flow do different jobs
Gas storage heats water in a cylinder. Continuous flow heats as water passes through the appliance. That difference changes how the installer checks capacity, available supply and several outlets being used together.
For continuous flow, tell the installer how many showers and other hot outlets run simultaneously. For storage, include busy periods and whether the supply runs out before the household has finished. Don't select a replacement by the number printed on the old unit alone.
Useful details for a repair enquiry
Include the brand, model, visible controller code and whether the issue affects every hot tap. Note whether the problem is constant or intermittent. If you can safely observe that other gas appliances are also affected, mention it without testing or adjusting anything.
Don't open a burner compartment, repeatedly attempt ignition or alter a gas fitting. If you suspect a gas leak, move away and contact the gas emergency provider directly. This online enquiry service isn't monitored as an emergency dispatch line.
Send a hot-water enquiryReplacing a gas system
Ask the provider to confirm gas supply, appliance location, ventilation or clearances where relevant, pipework, temperature control and commissioning. The exact installation requirements depend on the model and site.
If you're comparing a heat pump instead, ask for each option's full installation scope. A change in energy source can introduce electrical work and different space requirements. If the house keeps other gas appliances, include that fact when discussing ongoing supply charges.
Who does the work and what the quote covers
Ask the contractor to confirm the licences and registrations relevant to the proposed plumbing and gas work. Verify those details with Consumer and Business Services before work starts. The independent provider is responsible for assessment, workmanship and applicable compliance documentation.
Your quote should identify the model or repair part, labour, site changes, testing, removal and GST. For a possible warranty fault, contact the manufacturer or installer first so the correct service process is followed.
