Your installation is covered by our workmanship warranty as well as specific warranties supplied by the manufacturer of the various components, as per their own warranties. Your installation warranty is effective for 12 months from the date of installation; and is activated upon receipt of full payment for the job.

The Cylinder Guy will not be responsible for the costs of other plumbing or electrical company’s attendance.  Any workmanship related remedial activity must be undertaken by your installing tradesperson or by an alternative tradesperson of our choosing. Any deviation from this must be approved in advance and in writing (via text or email) by The Cylinder Guy Ltd or will cause the warranty to be void and costs will be incurred.

All installation work undertaken by The Cylinder Guy Ltd is covered by a comprehensive 12 Month Workmanship Guarantee against any defects raised against the work performed by the original contractor only.

For any hardware related failure, the manufacturer’s warranty will dictate response times and coverage. This information is available on the manufacturer’s website. Examples of the various types of warranties may include:

  • Stainless mains pressure hot water cylinders – 10 years on the cylinder and 3 years labour

  • Low-pressure hot water cylinders – 5 years on the cylinder with 1-year parts & labour

  • Electrical components (element & thermostat) – 1-year parts and 1-year labour

  • Valves – 5 years parts and 2 years labour

For the water heater itself, we typically request that you call the manufacturer’s 0800 contact number as this will result in the fastest remedy for you. For other hardware, such as valves/regulators/etc, your installing plumber will typically visit to repair or replace the failed component and may invoice the manufacturer directly:
