EL 500 Eco come in several different sizes from 204 kW up to 504 kW output. All may be supplied with a built-in safety system.

The new control system, reached by a touch screen, allows for simple operation and start-up. The customer is no longer dependent on the manual to the same extent. It also allows individual functions to be monitored according to each customer's needs. The overview of the boiler's parameters is easy-to-understand and convenient. For example, it is possible to view boiler output in addition to temperature.
Connecting to external equipment is simple, such as integration/control from a heat pump. All that is needed is a separate outdoor temperature sensor for outdoor temperature compensation.
All parameters are accessible via Modbus.

Our built-in safety solution (69-504 kW) is approved for installation without catastrophe protection, steam collector, level sensor or flow monitor.

For more information - see datasheet below.
