Electronic Dual Hot Water Cylinder Thermostat – ESCTDEB

£35.00

  • Easy to use & quick installation
  • Accurate temperature control
  • Automatic override killing legionella bacteria
  • Clear LCD display
  • Large adjustable dial
  • LCD to signal heat demand
  • Energy saving
  • 3 year warranty
The ESI electronic dual cylinder thermostat is a product developed with energy saving in mind. Hot water can be stored at any desired temperature between 25°C and 65°C and with an automatic one-hour boost to above 60°C any legionella bacteria is eliminated. The backlit LCD display shows the user both the current water temperature and the desired water temperature with a red LED light indicating when heat is in demand. A large dial makes setting the desired temperature simple, whilst the secondary thermostat (high limit) is pre-set at 80°C with a manual reset. Electronic sensors offer far greater temperature accuracy ruling out the need for physical contact unlike standard mechanical dual cylinder thermostats. Easy to install and economical by design, this cylinder thermostat is an ideal replacement.
