HT4 Series
The HT4 is Heatwells' biggest selling thermostat. Heatwell uses the HT4 in all of our new installations.
Heatwell's HT4 has been designed with simplicity of use in mind. We have stripped out functions that market research has suggested are not being used. All programming of the thermostat is done in a logical menu.
The HT4 series is available in both vertical and horizontal. There is the option of either black or white in vertical. The HT4 also has a dual function model that can operate both underfloor heating and heated towel rails.
The HT4 is perfect for new installations or as a replacement thermostat.

HT5 Series
The HT5 has been designed with the rest home / work from home market in mind. The HT5 is extremely easy to program and use.
The HT5 allows for one programmed period, and can also be operated manually. The HT5 comes with a touch screen and is one step better than a manual thermostat in looks and design.
The HT5 can be used like a manual thermostat. However, unlike a manual thermostat, maximum temperature can be digitally set and the thermostat can be locked.

HT-M
The HT-M is Heatwells' manual model. The HT-M is our simple solution. No programming required! Turn the unit on and off to the temperature you desire with a twist of a knob.
The HT-M is the perfect thermostat for users who only want to turn the underfloor heating on or off.
The HT-M has both horizontal and vertical models available.
The HT-M comes with an LED light that shows red when the unit is on standby, and green when the unit is heating. The twist knob is large and is easy to grip. Using the twist knob, the selected temperature clicks into place.

Thermostat Comparison
Heatwell recommends the HT4 for most installations and most thermostat replacements. Choose the HT3 if you need to have different programming times for different days, prefer a 24-hour clock, or want the option of a manual override. Choose the HT5 if you want a simple thermostat that is lockable. Choose the HT-M if you only want to turn the heating on and off.
