Why replace an old electric heating system or night storage heater?
Whether night storage heaters, radiators or convectors: many older electric heating systems date back to a time when electricity was cheap and efficiency was hardly a factor. But the reality has long since changed - technically, economically and ecologically.
At the same time, state-of-the-art electric heating systems are now available that are efficient, sustainable and intelligently controllable. With ETHERMA, you can easily switch to a heating system that is in tune with the present - and ready for the future..
❌ High power consumption & low efficiency
Old heating systems require a lot of energy to produce relatively little heat. Outdated components, inadequate insulation and simple controls result in unnecessarily high operating costs - especially in poorly insulated or only partially insulated buildings.
❌ Difficult to regulate heat emission
Night storage heaters store heat at night, which is then slowly released during the day - regardless of actual demand. This leads to overheated rooms in the morning and uncomfortably cold rooms in the evening. Individual room temperature control is virtually impossible.
Even classic radiators or older types of direct heating systems only offer rough control options, are often slow to heat up and cannot be compared with today's thermostatic or smart systems.
❌ Not sustainable
Most old appliances are not compatible with modern control systems, are not smart home-compatible and often do not meet the requirements of the current Ecodesign Directive (EU). They also lack safety features such as temperature drop detection and weekly programmes.
❌ Dry air - bad for health and indoor climate
Many old electric heaters - especially convectors - generate circulating warm air, which severely dries out the air in the room. This can not only affect your well-being, but is also problematic for allergy and asthma sufferers.
The result: irritated mucous membranes, increased dust circulation and an unhealthy indoor climate - especially in winter.
❌ Night-time electricity is no longer an advantage
Night storage heaters were once developed for cheap night-time electricity tariffs - but these price advantages have now disappeared in most regions. On the contrary, many tariffs have been adjusted or abolished. This results in high electricity costs at night without any real benefit.
