Start your day with a smile

Start your day on the front foot with perfectly warm floors and an unquestionable cosy environment, all powered by a smile. The Bluetooth Programmable Thermostat (BT21) makes controlling underfloor heating a doddle. Use the app to set up a heating schedule in seconds and the dial to adjust the temperature should you prefer a more manual approach.


Just 'tap' and 'twist'

At first glance the BT21 could be mistaken for a manual thermostat but there is more to it than meets the eye. So what’s the dial for? Just ‘tap’ and ‘twist’ it to adjust the Comfort and Eco modes. Everything else is done on the app!

Setting up the BT21

Designed to make heating control easier

‘Beautiful things that make your life better’ is a Scandinavian concept that has always been a highly regarded. Designed and made in Scandinavia, the BT21 takes this concept to a new level ensuring better control of your heating to help you live well.
