Common Questions
A: We have experienced installations where heating has been installed in these areas but subsequently the cable has been damaged by sub-trades when for instance working on drains within this area and the damage has not been picked up at an early stage.
In this event the whole bathroom floor will likely require replacing due to water proofing issues. Warmfloor does not believe this practise is worth the risk.
A: Yes, but the drawback is reduced heat transfer, making it less efficient and responsive as opposed to tiles.
It is preferable to use an insulation board first if over a concrete slab as laminate has a slow response so directing the heat up into the floor will speed heat up times and save on running costs, please see link to information on Insulboard on our website here

With our Warmfloor TH04 and TH05 thermostats you can limit the maximum temperature that the floor will reach by installing probes under the covering by setting the limiting temp at around 25 degs or whatever the product specifications allow.
You should be checking with the supplier/vinyl or laminate manufacturer regarding maximum temperatures for the product you choose.
NB : Our run cost calculator is applicable to tiles only as no testing has been performed on other surface materials .
A: Absolutely, these thermostats have been designed by Warmfloors Technical team, and ease of use was a priority in their design.
A: This output can be is used to control appliances such as heated towel rails and mirror demisters. Large savings can be made if you limit these appliances to say only two hours in the morning and also in the evening. This may result in savings of around $15.00 per month.
A: This is a basic APP that allows you to remotely turn your heating on/off and adjust the manual heating’s temperature set point using your phone as long as Wi FI is available. An important step often overlooked is to make sure your WiFi is set to 2.4 Ghz. More info is available here TH05 App & Downloads - Warmfloor Underfloor Heating New Zealand (warmfloornz.com).
A: As there are so many different platforms available Warmfloor has not tested this functionality for each, however we have a very good client that has it functioning very well with Home Assistant interfaced with HomeKit. See more info here TH 05 into Home Assistant (warmfloornz.com).

Without a doubt, one of the best companies I've ever dealt with. Outstanding customer service, excellent products, and a fantastic team. I wouldn't hesitate to recommend Warmfloor to anyone. Thank you again! ⭐⭐⭐⭐⭐"
Highly Recommended!
Posted on 01.08.2026"I honestly can't recommend Warmfloor highly enough! I accidentally overloaded a kitchen power outlet with too many appliances plugged into the same socket, not realising it would trip the power to my underfloor heating thermostat. From my very first phone call, the team was incredibly friendly, responsive, and helpful. They quickly organised a replacement thermostat, arranged for an electrician to install it, and made the whole process completely stress-free. Thank you again! ⭐⭐⭐⭐⭐"
