Disadvantages Of Radiant Floor Heating 

Radiant floor heating is a popular option in various countries but there are some problems with radiant floor heating. To make you aware of them, we have given a detailed explanation of the some dominant yet significant disadvantages of radiant floor heating.

  1. High Installation Cost 

Radiant heat cost per month is between $65 to $250, which is low but at the time of installation you need to do a bulky investment. To install radiant heating, you need to remove existing flooring to install heaters. That increases the installation costs. To avoid this you can use the specially designed pads between floor joists below your floor. However, this method needs access to the underside of your floors via a crawl space or basement areas.

  1. High-performance Green Homes Would Benefit Very Little From It 

Electric radiant floor heating may not be a good option for high-performance homes as such homes need low heating. So, for a little heating you don’t need to install such an expensive heating system. Other less expensive heating options can provide the same level of comfort, especially when the building envelope already does a fine job.

  1. Time Lag Of Heat Movement Through Flooring 

While knowing the pros and cons of hydronic radiant floor heating, you should know that there is a time lag of heat movement through the flooring. And this can lead to an overheating if there are other sources including passive solar, already delivering heat to a space. It might be best to disable or avoid installing radiant heating system slabs where solar heat will already heat the air more directly.

  1. To Be Effective, Floor Covering Must Be Thin 

After installation of the radiant flooring you need to buy some attractive and thin covering for it. The covering should not insulate the heating system from the room so, they should be conductive. Ceramic tile is an excellent and effective floor covering for radiant floor heating systems, but thin carpeting and wood are also used.

  1. Consistent Heat May Not Be Desirable For Some People 

Some homeowners don’t want continued heat so for them radiant floor heating is not a good choice. So, then you don’t need to pay out the high radiant heat flooring cost. Some people like to turn their heat on and off at different times of the day.

  1. Less Efficient For Bigger Rooms 

Hot water radiant floor heating systems are good for small sized rooms with lower roofs but they are not effective when installed in bigger rooms.
