The ETHERMA EFW frost monitor is the ideal electric direct heating system for small rooms where reliable temperature control and protection against frost are important. Whether in the guest WC, cellar room, conservatory, tool shed or utility room - the EFW ensures pleasant temperatures even at low outside temperatures.

Thanks to the plug cable with earthing contact plug, the frost monitor is immediately ready for operation - simply connect and switch on. The infinitely adjustable thermostat control allows the temperature to be set between 5 and 15 °C as required. An integrated indicator light reliably displays the active heating mode - for maximum transparency and control.
