T-Smart is the most radical evolution of technology in the immersion sector for some time. The T-Smart is the future of hot water heating and is the first generation smart immersion of its kind in the UK. We believe T-Smart will be for hot water what Nest and Hive have become for central heating, providing the homeowner with full smart control of the cylinder.

  • 2 1/4″ Head
  • 27″ Long
  • The T-Smart is the first smart immersion that will upgrade your cylinder to a genuine smart appliance
  • This upgrade will give the home owner complete control remotely over their hot water when its needed via the app
  • Built in programmers, planners and timers provides unlimited time and temperature settings via the T-Smart app giving the homeowner complete flexibility and control
  • The T-Smart learning function understands homeowners water usage and provides hot water when its needed most based on historical usage
  • Energy efficiency – The T-Smart only uses the energy that’s needed and raises the water temperature in the most energy efficient manner to help reduce the homeowners energy consumption
  • The Built-in anti legionella function gives additional piece of mind that the system will be continuously protected from bacteria growth carrying out the antibacterial cycle at least once every 15 days
