Heatwell has been installing underfloor heating in NZ since 2000.  Over that period, we have used a range of thermostats.  We now design and use our own range of exclusive thermostats. 

​

We no longer carry any parts for any of our older models, nor do we have a programming service for thermostats that are not a Heatwell product. All thermostats we have previously installed can be replaced with on of our current series of thermostats.

 

We recommend the HT4 as the replacement.​​​​
