Do “mud jobs” work well for radiant floors?
Concrete (or gypcrete) below tile is the most popular floor surface for radiant heat. It is relatively inexpensive and easy to install radiant tubes in the “mud”, and the resulting surface transfers heat well, allowing the use of very low water temperatures. Such floors store heat well too which is an advantage if the heat goes off, but it means that they are not responsive in that it takes a long time for them to heat up or cool down.
