Heating a Sunroom

Whether you're heating an enclosed porch or looking for sunroom heating alternatives, WarmlyYours is sure to have the perfect radiant heating product for your needs.

Heating a sunroom can be tricky due to its proximity to the home's exterior and the typically large windows. Electric floor heating or radiant heat panels can be great ways to supplement your existing heating system and help increase your comfort in these rooms when the weather turns colder.

Frequently Asked Questions


Sunrooms can be very cold during the winter months. While a furnace may push some warm air into the room, the large number of windows, exterior walls, and other causes of heat loss in a sunroom will typically keep it from having a comfortable temperature level. Floor heating and radiant panels will add radiant heat, which the human body absorbs faster than other forms of heat, to the room so that it feels warm even at lower temperatures.

17 people found this helpful.  Did you find this helpful? Yes No

Floor heating will typically add the most heat to supplement an existing heating source and it will not take any extra space since it is embedded in the floor. If you are not remodeling your floors but have some open wall space, you should mount a radiant panel. For the most effective results, install the panel so that it points toward the area where you will spend most of the time.
