DIRECT HEATING DEVICES For bathrooms and living rooms.

ETHERMA DUO PLUS The convector storage heater with additional heat

The ETHERMA DUO PLUS direct heating device is a modern convector storage heater and is impressive in three respects when it comes to heating technology: convection, radiant heat and heat storage are combined in a unique combination and not only ensure more performance, but also optimize operating costs. Due to the compact design, the powerful heater is extremely space-saving and at the same time generates pleasant radiant heat. Thanks to the built-in electronic control, the desired room temperature can be selected with a flick of the wrist.

The convector is ideal for large rooms as efficient transitional heating and as a modern replacement for outdated night storage heaters. The ETHERMA DUO PLUS is not only characterized by its modern, puristic design, but also by its rapid heating reaction. In the OFF state of the controller, the frost protection mode of the heater remains active. In the event of an unexpected drop in temperature, e.g. due to an open window, the device automatically switches to OFF mode. In addition, the ETHERMA DUO PLUS can be adapted to the individual wishes of the residents in no time at all with the daily and weekly programs. The convector storage heater can be mounted horizontally on the wall and is simply connected via a connecting cable with a plug. 

 

YOUR ADVANTAGES:

  • Triple heat emission: convection, storage and radiant heat

  • Ideal for large rooms 

  • Electronic control for easy temperature setting

  • Convenient daily and weekly programming

  • Energy-saving function through temperature shock detection - the device automatically switches to frost protection mode

REPLACEMENT OF NIGHT STORAGE HEATERS

Electric heating still has to fight against its wrongly bad reputation. Many prejudices are based on the disadvantages of the bottom line inefficient and expensive night storage heaters of the post-war period. This heating system is characterized in particular by its poor controllability - based on the temperatures of the previous day, charging takes place at night and delivery the next day. In most cases, what you have too much heat in the morning is missing in the evening and has to be heated up at great expense. In addition, allergy sufferers often have problems due to the strong dust turbulence and older models are harmful to health due to asbestos shoring.

However, modern, efficient electric heaters such as the ETHERMA DUO PLUS no longer have anything in common with these outdated heaters and are ideal as a replacement, especially if you do not want to install subsequent, costly piping for a water-based heating system.

 

DISADVANTAGES OF AN OLD NIGHT STORAGE HEATER

  • High space requirement

  • Mostly containing asbestos (old models)

  • Expensive disposal (asbestos)

  • Strong dust turbulence

  • Soot formation

  • Hard to regulate

  • Fluctuating temperatures

  • Expensive heating

  • High kW power required
