Radiant tubing installation in concrete slabs on grade are more affordable than tubing installed with wood framed floors. For an average 1600-2400 square foot home, expect $6,500-$35,000 for a typical radiant floor heating system. Radiant floor heating is an expensive mechanical system. Radiant floors do not cool or de-humidify. Buildings and furnishings also appreciate the less-humid conditions that we enjoy. Unless one has a high elevation building site, a means of cooling with de-humidification is needed to stay comfortable in our increasingly hot and humid summers. There are many ways for keeping cool in the summertime without AC, but none of them include radiant floors. So if heat pumps are involved, why do you need to include radiant floor heating? Most homes need to cool and de-humidify in our climate for part of the year and the only capable appliance is a heat pump. This is why radiant floor heating is not popular in the Southeast US climate. This reasoning calls into question the whole idea of radiant floors and high mass. Its still important to note, that their system will have a slower response than forced-air. This warmboard advertiser's video on FHB's site demonstrates how their system has quicker thermostat response than concrete or gypsum-based, embedded floor tubing. Some radiant floors do better in this respect than others. Passive solar design is particularly vulnerable to radiant floor's thermostat response delay. Radiant floors are much slower to respond to thermostat changes based on occupant and environmental dynamics. Mood, state-of-rest, outdoor influence, individual preferences all benefit from quick changes in indoor-air temperature. Professionally designed, installed and verified ducts, result in a forced-air system whose operation is barely noticeable.įorced-air systems respond to thermostat changes quickly.
#RADIANT HEAT FLOORING COST CODE#
Modern, minimum code performance homes have very low CFM (air-flow) requirements. Most people have experienced unpleasant forced-air systems. Once again, the comparison relies on a poorly built building envelope. This common illustration is supposed to represent radiant floor heating versus forced-air. This is information and opinions that I like to share with everyone regarding radiant floor heating. We include radiant floor heating for clients that request it. This makes more sense for goals of warm feet, thanks to the limited area. Some projects are only interested in radiant floors for bathrooms.
This is a good thing, it means less wasted energy. What is a Building Envelope? The Blower Door Test.Įnergy efficient building envelopes almost eliminate feelings of warm feet. Dont miss the most cost-effective opportunties. If you can feel the radiant floor heat by touch, on an average winter day, the home is likely inefficient and was probably not proven airtight with a blower door test. Sorry, but these experiences typically come from homes with poor performing building envelopes. Many who have lived with radiant floor heating, insist on including it in their new home project based on their experience with its comfort. Some situations deserve them while most projects in our climate will struggle with their cost-effectiveness. While most radiant floor systems exist in the great white north, it is often a hard decision to include them in the Asheville and WNC climate.
Radiant floor heating is known for its efficiency and comfort.
