New Zealand’s Healthy Homes heating requirements are designed to ensure rental properties have adequate fixed heating in the main living room.
For landlords, simply having a heater in the property does not necessarily mean the rental meets the Healthy Homes Standards. The heater must meet specific requirements and provide enough heating capacity for the living space.
Here is what landlords and property managers should check.
What Are the Healthy Homes Heating Requirements?
Under the Healthy Homes Standards, qualifying rental properties must generally have one or more fixed heaters in the main living room. The heating system must be capable of heating that room to the required standard.
The amount of heating capacity needed depends on factors such as:
- Living-room size
- Ceiling height
- Windows and glazing
- Insulation
- Walls and floors
- Local climate
- Heat loss from the room
This means two properties with similar floor areas may require different heating capacities.
What Counts as a Fixed Heater?
A qualifying heater generally needs to be permanently installed rather than a portable appliance tenants can move between rooms. Depending on the property and required heating capacity, suitable heating may include:
- Heat pumps
- Fixed electric heaters
- Wood burners
- Pellet burners
- Other qualifying fixed heating systems
The heating system must also be in working condition.
Are Portable Heaters Enough?
Portable heaters generally should not be relied on to satisfy the Healthy Homes heating standard. Providing a portable fan heater or oil column heater does not automatically make a rental property compliant.
Landlords should instead check whether the property’s fixed heating meets the required capacity and other applicable conditions.
How Much Heating Does a Rental Property Need?
There is no single heater size that works for every New Zealand rental property. Heating capacity is calculated from the characteristics of the main living room.
A large open-plan living area with many windows may require substantially more heating than a smaller, well-insulated room. Use the official Tenancy Services heating calculator rather than guessing from room size alone.
What Is the Main Living Room?
The heating requirement focuses on the property’s main living room. This is usually the primary space used for everyday living, such as a lounge or an open-plan lounge and dining area.
The required heating capacity should be assessed for that space rather than simply choosing the largest room in the property.
Does an Existing Heat Pump Automatically Comply?
No. Having a heat pump installed does not automatically mean the property satisfies the Healthy Homes heating requirements. You still need to determine whether the heat pump provides sufficient heating capacity for the main living area.
If the room requires more heating capacity than the existing heat pump can provide, additional or replacement heating may be necessary.
Healthy Homes Heating Checklist for Landlords
- Identify the main living room
- Check what fixed heater is installed
- Confirm the heater is operational
- Determine its heating capacity
- Calculate the required heating capacity
- Compare installed capacity with the requirement
- Keep evidence of the calculation
- Record the heating information for Healthy Homes documentation
Invoices, specifications and assessment records can help show how compliance was determined.
Heating and the Healthy Homes Compliance Statement
Heating information is also relevant when completing the property’s Healthy Homes Compliance Statement. Landlords should maintain accurate information about the heating system and how the required heating capacity was determined.
For the full documentation checklist, read Healthy Homes Compliance Statement: Requirements and Checklist NZ.

Common Heating Mistakes
Assuming any heater qualifies
The type, installation and heating capacity all matter.
Using only portable heaters
Portable heaters generally do not satisfy the fixed-heating requirement.
Guessing the required capacity
The required heating output depends on the property and should be properly calculated.
Ignoring changes to the living area
Renovations or changes to an open-plan space can affect heating requirements.
Not keeping records
Keep evidence showing how the heating requirement was assessed.

How do I calculate the required heater size?
Use the official New Zealand Healthy Homes heating calculation method or the government Heating Assessment Tool for the property.

Final Thoughts
The Healthy Homes heating requirements are about more than simply installing a heater. Landlords need to ensure the main living room has qualifying fixed heating with enough capacity for the property.
Start by checking the existing heater and required capacity, then use our Healthy Homes Pre-Check NZ to review the property’s other Healthy Homes requirements.
