Why the exchange is worthwhile

Replacement night storage ovens

Heating in the living room

Alternative to the night storage

More than 1.3 million night storage heaters are still in use in Germany as a heating medium. Most users hesitate to replace the old furnaces. Partly because disposing of old night storage heaters is often difficult and expensive, partly because there is uncertainty about which heating system to use in place of the night storage heater. Replacing it with an electric heating system can often be very worthwhile. Modern electric heating systems are much more economical than older night storage heaters. This often far outweighs the slightly cheaper electricity night tariff. Compared to the installation of a oil or gas heating system, the AeroFlow® surface storage heater stands out for its low purchase cost. In addition, there are no recurring costs for maintenance or chimney sweeps, which would otherwise add to the financial burden.

Fix & Flip renovation

Stairs in a renovated house

Upgraded with the use of AeroFlow® electric heaters

Renovating and renovating real estate

Buying a property, renovating it, staging it, and then selling it for a profit: This strategy is called Fix and Flip. What has been common practice in the USA for some time is gaining more and more popularity in Europe in recent times as well.

The use of AeroFlow® electric heaters is ideal for this concept: since the purchased property has old night storage heaters, they can be replaced with modern underfloor storage heaters without incurring prohibitive costs.

After the dismantling and disposal, only the power connection needs to be modified, and the installation of the new heating system is no longer a problem.
