that can also be a very challenging and costly procedure, as a lot of significant modifications to your flooring will be required.

Floor Height: Radiant floor heating increases the height of your floor.

Electric-radiant heated floors can add about an inch of height to your existing floor, while hydronic radiant heated floors can elevate the height even more.

Adding insulation boards or a membrane to make the heating system more efficient will further increase your floor height.

This may cause issues if you have inward-opening doors in your room or place.

The door may not open or can always be stuck in between whenever you open it.

Height increase can also be a problem if you are installing radiant heating in a room with a low ceiling height.

Replace Old Flooring: If you want to install a new radiant heating system you will have to replace your existing flooring.

and if the flooring is thick then the under-radiant heating system won’t be that much effective causing you a loss of money and time.

Lag in Heating Process: Another drawback is a lag in the heating process that can lead to an overheating situation for you.

This can occur if there is another source of natural heating taking place at the same time such as passive sunlight the sun that is already delivering heat to your space.

The heat from the sun will get your space heated up directly from the air in no time and radiant floor heating will only become useless.

Constant Heat: If you want constant heating and at the same time if you are a person who likes switching on and off their heating system often…

then it will be a drawback for you to have radiant floor heating because it takes longer time to warm up a room or space from 0 to 100.
