Replacing old radiators before it's too late

Replacing old radiators before it's too late


When renovating a property, it makes sense to replace the old radiators with new ones. As a result, energy efficiency can be significantly improved.

When older flats are renovated, it is usually necessary to replace the heating systems. Therefore, it is especially beneficial for energy efficiency, even if the radiators are also renewed. As a result, the heating works more economical than before. Even if additional heating systems such as floor or ceiling heating are used, many property owners opt for a complete renewal.

Important arguments for new radiators

Old radiators need more energy than new ones, so they pollute the environment relatively strongly. Since they contain about 60 percent more heating water than the new radiators, the heat can not be regulated so well. In addition, the old radiators rarely work together with modern heat pumps or solar panels. In such cases, an exchange is necessary. New radiators then ensure a pleasant room climate and a low heat and energy loss.

Further information on radiator replacement

The screw connections must be loosened and the radiators themselves carefully removed from the holder and from the connections. Partly the old radiators are screwed directly to the wall, partly to special fixings. The residual water in the radiator can be extremely dirty, so care should be taken when handling the components. During installation, the new radiators are mounted on the previous or new brackets. Before any drilling, existing lines must be observed.

Important steps when renewing the radiators
