The wHT4 is Heatwell's wifi compatible model.  Program your preferred options from the Tuya Smart app off your smart phone.  Turn your floor heating on or off from anywhere in the world!

The wHT4 is very easy to program, and can be used as a new install or as a replacement for an existing thermostat.

​

The wHT4 comes in three parts. The thermostat, the mounting block, and the electrical block. The thermostat attached to the electrical block via an electrical ribbon.  The electrical block acts like a circuit breaker for an electrical surge. The electrical block is the part likely to be affected by an electrical surge and can be replaced without having to buy another thermostat.

​

The wHT4 can replace any existing Heatwell thermostat (from the HT2 up) without the need of an electrician!

All Heatwell thermostats come with a 2-year warranty.  All thermostats are tested in NZ, and come pre-set. ​​
