ELENSIO 200 AND 250:
Thermodynamic water heater on ambient air or on outside air with electrical resistance. A range of thermodynamic water heaters operating on extracted air with electrical backup

Thermodynamic water heater on ambient air or on outside air with heat exchanger for connecting to a boiler or solar, and electrical resistance.


  • Max. operating temperature: 90 °C
  • Max. operating pressure: 10 bar
  • Air temperature for thermodynamic module
  • operation: - 5 to + 35 °C

Floor-standing thermodynamic water heaters with storage:

  • 200 and 250 models with 1.8 kW backup electric heater
  • 250H and 250H models with exchanger for connection to a solar hydraulic backup or via boiler and 1.8 kW backup electric heater
  • A range of thermodynamic water heaters operating on extracted air with electrical backup
  • Maximum volume of hot water at 40 °C from 260l for the 200 model up to 338l for the 250 model
  • DHW reheating up to 65 °C by the heat pump
  • Enamelled tank, protection via impressed current titanium anode
  • New very high-performance exchanger
  • Controller for a DHW application integrating programming, various operating modes, backup management, anti-legionella function, frost protection mode, automatic defrosting, energy metering estimates, night backup management, optimised or hybrid function.

Each boiler is delivered with an energy label displaying a range of information, including energy efficiency, annual energy consumption, manufacturer name and noise level. By combining your boiler with, for example, a solar system, DHW storage tank, control system or even another generator, you can improve the performance of your installation and generate a corresponding "system" label.
