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