As a landlord or property manager in NSW, understanding your obligations under the Residential Tenancies Act 2010 (NSW) is essential – including your duty to maintain a working hot water system. This guide covers what the law requires, how quickly you must act, what replacements cost, and what tenants can do if you don’t comply.
What Type of Hot Water System Must a Landlord Provide?
The NSW Residential Tenancies Act does not specify a particular hot water system type – it requires that the system is functional and capable of supplying hot water at adequate temperature and pressure. Here are the common system types found in NSW rental properties:
Electric Storage Hot Water Systems
Electric storage tanks (typically 125-400 litres) are the most widely installed hot water system in Australian rental properties. They are the cheapest to purchase and install, though more expensive to run than gas or heat pump systems. A standard 125-160 litre electric storage system is generally considered adequate for a property housing two to three people.
Gas Storage and Instantaneous Systems
Gas hot water is common in Sydney’s inner and north shore suburbs where gas supply infrastructure exists. Gas storage systems work similarly to electric systems. Gas instantaneous (continuous flow) systems heat water on demand with no tank. Both provide adequate hot water for residential tenancies and are acceptable under the RTA.
Heat Pump Hot Water Systems
Heat pump systems are growing in Australian rental properties, particularly as the NSW Government has offered rebates through various energy efficiency programs. Under the NSW Residential Tenancies Act, a landlord is not required to install a heat pump – any working system that delivers hot water at adequate temperature meets the obligation. If a heat pump system fails, the landlord must repair or replace it within the required timeframe.
Solar Hot Water Systems
Solar hot water systems are present in some NSW rental properties, particularly in regional and coastal areas. They require a gas or electric booster for periods of low solar radiation. The entire system – panels, tank, and booster – must be maintained and functional to meet the landlord’s obligations.

A hot water system failure is an urgent repair under the NSW Residential Tenancies Act, and in practice NCAT consistently expects a landlord to arrange repair or a licensed tradesperson assessment within 24 hours of being notified. If a same-day repair is not possible, the landlord should arrange temporary accommodation or portable hot water provision, or accept reimbursement for the tenant’s own urgent repair arrangement.
- Tenant notification: The tenant notifies the landlord or agent of the hot water failure – in writing where possible (SMS or email is sufficient under the RTA)
- Landlord response window: The landlord must respond with a repair arrangement within a reasonable time. NCAT treats 24 hours as the maximum for hot water as an essential service
- Tenant self-help right: If the landlord does not arrange an urgent repair within a reasonable time, the tenant may arrange their own repair through a licensed plumber or hot water technician, up to a cost of $1,000, and recover the expense from the landlord
- Tribunal enforcement: If the landlord refuses to reimburse or refuses to repair, the tenant can apply to NCAT for a repairs order and compensation
Landlords and property managers in NSW should have a licensed plumber or emergency hot water service on call for exactly these situations. Delays of 48 hours or more without an adequate explanation consistently result in NCAT orders against landlords in NSW.
What Are the Costs of Hot Water System Replacement for Landlords?
Hot water system replacement costs for NSW landlords typically range from $800 to $3,500 fully installed, depending on system type, size, and installation complexity. The table below outlines typical market ranges for Sydney and the Central Coast.
