What is the minimum clearance around a hot water system?

Summary (TL;DR)

AS/NZS 3500.4 requires water heaters to be installed with adequate clearance for maintenance and replacement. For gas continuous flow units, AS/NZS 5601.1 mandates specific clearances from windows (usually 300mm-500mm depending on the flue) and internal corners.

Hot Water System Clearance Rules

When installing a new hot water system, you must satisfy both the plumbing standards (AS/NZS 3500.4), gas standards if applicable (AS/NZS 5601.1), and the manufacturer's specific installation instructions.

General Access (AS/NZS 3500.4)

The standard dictates that all water heaters must be placed so that:

The rating plate and warning labels are visible
The thermostat, heating element, and burner can be accessed and removed
The PTR (Pressure Temperature Relief) valve can be safely operated and replaced
The entire unit can be removed and replaced without causing structural damage to the building

Gas Continuous Flow Clearances (AS/NZS 5601.1)

For external gas continuous flow heaters, the flue terminal clearances are strict:

From a window or door: Typically 300mm horizontally, but 500mm if the opening is above the flue.
From an internal corner: Minimum 300mm.
Below an eave or overhang: Minimum 300mm.

Indoor Storage Heaters (Safe Trays)

If an electric storage heater is installed indoors (e.g., in a cupboard), it must sit in a safe tray. There must be at least 20mm clearance between the water heater and the sides of the safe tray to allow water to flow freely to the tray waste.
