Cons:
  • High initial cost: Radiant heating systems can be more expensive to install than traditional heating methods. ...
  • Limited to certain spaces: Radiant heating systems are best suited to spaces with high ceilings or large open spaces, where traditional heating methods can struggle to provide adequate warmth.

Is radiant heat worth the cost?

Radiant heating has a number of advantages. It is more efficient than baseboard heating and usually more efficient than forced-air heating because it eliminates duct losses. People with allergies often prefer radiant heat because it doesn't distribute allergens like forced air systems can.

Should you turn off underfloor heating in the summer?

Benefits of Turning Off Underfloor Heating in the Summer

Moreover, operating your UFH system continuously during the summer may incur higher maintenance costs and strain the system, reducing its lifespan.
