Newly overlapping demand can expose a capacity limit, but a fault or restricted water flow can produce similar symptoms. Note which outlets overlap and what changes at each tap. Stately covers Whangaparāoa for gasfitting. Start the conversation with your household’s changed routine, rather than a replacement model.
Describe the overlap that changed your mornings
Tell us whether the problem began when another person moved in, a bathroom started getting used, or shower times changed. Separate a temperature drop from weaker water flow. Explain whether both showers change together, or only the outlet opened last. Those details help shape the assessment.
Use observations from ordinary use rather than opening appliance covers or adjusting gas controls. Have the unit’s make and model available if already recorded. Mention whether hot water recovers when another tap closes. A unit that previously suited staggered showers might struggle with the same household using them together.
Compare delivered hot water with actual demand
We check the appliance details against the outlets you want running together. The useful comparison is delivered hot water at the required temperature rise, not just the flow figure printed in advertising. Colder incoming water requires more heating for the same outlet temperature, which affects the comparison.
We also assess water flow and temperature at the affected outlets. A shower mixer or outlet restriction can change what you experience even when the heater is operating. The aim is to distinguish an appliance capacity limit from a distribution problem before you commit to equipment that might not solve the complaint.

Check the supply before increasing appliance output
A larger heater needs more than a convenient place on the wall. We confirm the gas supply at your address, including whether the installation uses natural gas or LPG. We assess the existing supply arrangement and other connected gas appliances against the proposed unit’s requirements.
For LPG, the assessment includes the cylinder and regulator arrangement. For either fuel, the gasfitter checks pipework suitability and the manufacturer’s installation requirements. Location, flue arrangements and ventilation are checked for the actual appliance. These checks belong in the replacement decision, rather than becoming surprises after you have selected a higher output model.
Choose between repair and a capacity change
If testing finds a service or repair issue, we explain that finding separately from capacity. Restoring normal operation and increasing available hot water are different outcomes. Ask whether the proposed repair addresses the new overlap or simply returns the appliance to its previous performance.
If replacement is appropriate, base the selection on the outlets you genuinely need together. Discuss whether staggering a particular use would suit your routine before changing equipment. Any gas work must be done by a licensed gasfitter. Check the PGDB register. Leave gas adjustments, disconnection and installation to that person.
Handover should answer the original complaint
After the agreed work, ask how operation was checked against the overlap you described. Keep the appliance details, operating instructions and explanation of any remaining limits together. You should understand what was repaired or installed and whether further plumbing investigation is recommended for an affected outlet.
Connected gas work needs a Gas Safety Certificate. General and high risk gasfitting also needs a Certificate of Compliance. For servicing or repair, obtain the applicable paperwork for the actual work. If you smell gas, avoid flames and switches, leave the area and call from outside. Keep the certification paperwork with your appliance records.
Gas fitter: questions from Whangaparāoa
Will turning up the temperature fix overlapping showers?
A higher setting does not increase the heater’s output capacity. Explain the symptoms to the gasfitter rather than treating temperature adjustment as a repair.
Should I buy the largest replacement available?
Choose against measured demand and the installation assessment. A larger appliance still needs a suitable gas supply and compatible water delivery to serve those outlets.
What if only one shower changes temperature?
Mention that distinction when booking. It helps focus checks on the affected outlet and its mixer as well as the heater, rather than presuming insufficient capacity.
