Older Heatwell Thermostats

Heatwell has been installing in NZ since 2000.  Over that period, we have used a range of thermostats.  We now exclusively design our own thermostats.  Ex-models include:

  • Heatwell HT2​

  • Heatwell TR 8100V

  • Siemens RDE100​

  • Siemens RDE20

  • Aube TH232​​

  • ​HNB TX928H

We no longer carry any parts for any of the above models. All models can be replaced with our current series of thermostats.

​​

Install videos and instruction manuals for our ex-models are available on this website.
