Terms & Conditions

General information about your warranty

When it is installed, tested and signed off by an authorised Thermafloor NZ installer, your UNDERTILE Thermafloor heating system is warranted for the LIFETIME of the floor covering under which it is fitted, except where the exclusions listed below apply.

  • You will need to provide us with proof of your purchase to be able to take advantage of our Lifetime Warranty. It is therefore important that you keep written proof of your purchase.
  • If you are the first owner or occupier of a property where a Thermafloor NZ undertile heater is installed, our warranty will be automatically transferable to you from the developer or builder of your property.
  • If you are not the first owner or occupier of the property, our Thermafloor NZ Lifetime Warranty may be transferable at the discretion of  Thermafloor NZ to a new owner of the residence in which the heater is installed, on written application by you to Thermafloor NZ.
  • Nothing in this Lifetime Warranty is intended to affect your rights under the Consumer Guarantees Act or any other law in New Zealand extending any product warranties or protections to you.
  • Before your floor covering is installed, you must make sure that your Thermafloor NZ installer checks and confirms to you that your undertile heating is working.
  • You must have 5 -10 spare tiles available to use in case we need to remove any of your tiles to make a repair.
  • Thermafloor NZ thermostats installed with your heater are guaranteed against manufacturing faults for (2) two years.
If this warranty applies Thermafloor NZ will:
  • Repair or replace your heater free of charge. Repair or replacement will be at Thermafloor NZ’s discretion.
  • Meet the cost of the repair or replacement of your heater.
  • Meet the cost of lifting and replacing the tiles we need to lift and replace to make our repair. We will use your spare tiles, so long as you have kept sufficient spare tiles for us to do so.
This lifetime warranty applies only if:
  • Your heater is installed, tested and signed off by an authorised Thermafloor NZ installer.
  • Your heater purchase is registered with Thermafloor NZ within 30 days after purchase. (Registration can be completed by filling out the warranty card enclosed with your heater and posting it to Thermafloor NZ).
  • You provide us with written proof of your purchase, and your account with your installer is fully paid up.
  • Your heater has been earthed and protected by a Residual Current Device (RCD) at all times.
  • You are the original purchaser of the heater and remain the owner of the residence in which it is installed. (Unless you provide us with written proof of Thermafloor NZ’s approval of the transfer of the warranty to you).
  • The floor covering over the heater has not been damaged, lifted, replaced, repaired or covered with subsequent layers of flooring.
Thermafloor NZ is not responsible for:
  • Damage done or repairs required as a consequence of the faulty installation or application of your heater.
  • Damage done as a result of environmental factors affecting your heater which are beyond Thermafloor NZ’s control.
