How long does it take to heat up apartment?

The time it takes to heat up an apartment depends on several factors, including the size of the space, the type of heating system, insulation quality, and the initial temperature. Typically, a well-insulated apartment may take around 30 minutes to a couple of hours to reach a comfortable temperature. However, older buildings with poor insulation may take longer. Additionally, the heating method (e.g., central heating, space heaters) can significantly impact heating time.
