Bay of Plenty Regional Council 

• Hot Swap home insulation loans are only available if the property has compliant heating.  

• Compliant heating includes no heating; heating appliances that don't burn wood or coal; or a legally established, compliant wood burner or legally established, compliant pellet burner installed after Sept 2005.  

• If there is a non-compliant heating appliance in the property it must be removed before an insulation loan can be approved.

You can also use Hot Swap to warm up your house with new heating.  To improve Rotorua's air quality old wood burners can be "swapped" for heat pumps, infrared heaters, gas fires, low and ultra-low emission wood burners. Hot Swap is a loan offered to Rotorua ratepayers whose properties fall in the Rotorua Urban Airshed Boundary.
