Old electric heating or night storage heater?

Switch to a modern electric heating system!

Heating replacement is currently high on the agenda for many property owners, property managers, and renovation projects-especially where old night storage heaters, electric radiators, or inefficient convectors are still in use. This is because outdated heating appliances not only cause high electricity costs, but also no longer meet today's requirements for energy efficiency, living comfort, and climate protection.

Replacing your heating system makes particular sense in older buildings, during partial modernization or as part of a complete renovation - and with modern electric heating systems, it's easier than ever. Whether you're replacing night storage heaters, radiators or direct heating elements, ARC offers customized, future-proof solutions that can be implemented quickly, cleanly and without major structural work.

Heating in winter, cooling in summer

Year-round climate control with just one device

No bulky outdoor unit

No visible outdoor units on the façade

Only two discreet core drillings

Minimal intervention in the building fabric, visually unobtrusive

State-of-the-art heat pump technology

Saves energy and significantly reduces operating costs

Space-saving integration

No external compressor, flexible installation options

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. 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 Outdated components, inadequate insulation and simple controls result in unnecessarily high operating costs - especially in poorly insulated or only partially insulated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

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 Outdated components, inadequate insulation and simple controls result in unnecessarily high operating costs - especially in poorly insulated or only partially insulated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.

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.

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.
