Underfloor heating can be used to simply warm your floor or act as a primary heat source. One of the biggest reasons to upgrade to underfloor heating is the level of energy efficiency it will allow. It requires a lot less energy, for example, in order to heat up a room fully, underfloor heating only needs to reach around 29 degrees. Also, underfloor heating doesn’t suffer from COLD SPOTS, and warms up the whole area uniformly.
