Frequently asked questions

Do gas hot water systems require a licensed gasfitter in NZ?

Yes. NZ law requires a certified gasfitter for all gas hot water systems, fireplaces and appliance installations. This ensures safety, compliance and proper performance.

Do gas appliances need regular servicing in New Zealand homes?

Yes. Gas appliances should be serviced every 12 to 18 months to maintain safety and performance. Regular servicing helps prevent leaks and keeps your system compliant.

How do I know if my gas hot water system needs replacing?

Fluctuating temperatures, low pressure, unusual noises or an older system can indicate it's time to replace your gas hot water unit. HW Group can assess it and advise whether repair or replacement is best.

What should I do if I smell gas in my home?

If you smell gas, turn off the appliance, ventilate the area, leave the home and contact a licensed gasfitter. HW Group provides gas leak detection and repairs during business hours, Monday to Friday 7am to 5pm.
