Radiant Cooling

in Radiant Heating
Greetings,

I am working on a 6,000 sq. home which continues to grow. The homeowner has added a guest bedroom, bath and foyer area in the basement, incorporating 481 sq. ft. Heating will be provided via radiant floor using Uponor or equal QuickTrak floor panel on top of the existing concrete floor. But the heat gain is only 1,250 Btuh. Since the cooling load is less than 2.5 btu/sq.ft, I am inclined to install some QuickTrak on the ceiling and circulate chilled water through the panels. I would control humidity with a Thermastor Products UltraAir XT-70 dehumidifier with a duct system to provide air movement and ventilation air. Any comments on this plan?

    Sq. ft.

    That's a really low load. Where did those numbers come from?

    Cooling Won't Work

    Need the slab and you may have a shot at it. Hopefully have 5/8" in the slab but 3/4" would be preferred.. No way your going to do it in the ceiling with 5/16 tubing..
