Flow Through Heater XL

Flow Through Heater XL

The FTH XL is an instant flow through heater based on a thick film heating element. The maximum power is 3400W at 230V. The FTH XL is able to handle high flow rates at a low back pressure since its channel size is twice as large as the FTH mkII. This results in a high flow of  hot water in just seconds. Energy efficiency is key because you just heat what you need!.


  • Instant hot water up to 100dC in just seconds. No water storage!
  • No standby mode required / low energy consumption
  • Integrated temperature sensing (NTC) and thermal protection (E-Fast)
  • Prepared for electronic volume measurement
  • Friendly with regards to lime scale forming and easy to descale
  • Compact design
  • FDA compliant
