The complexity of the system adds to the cost and air conditioning must be added separately.
In floor radiant heating and cooling.
Incoming cold water from the homes well is directed through the radiant tubing prior to reaching the tap.
Since radiant heating systems tend to be in the floor the obvious choice would be to use the same circulation system for cooled water.
Radiant cooling systems have been embedded in the ceilings of adobe homes taking advantage of the thermal mass to provide a steady cooling effect.
In a hydronic radiant floor heating system plastic tubing distributes hot water around the house from a central manifold like this one.
The cost up charge is minimal potable water rated tubing stainless or brass circulater and few other hardware items.
A typical circulation pump consumes only 5 amps when cooling or heating a house.
Radiant cooling can be use in conjunction with radiant heating systems utilizing the same network of raupex pipe embedded in a surface.
Radiant cooling is an energy efficient way to address sensible loads in a space.
No hot or cold spot and no wind noise or draft occurs when cooling with radiant floor heating.
While this makes sense in some cases delivering cooling from the ceiling has several advantages.
Radiant floor cooling radiantec has promoted open direct radiant floor heating that also has a limited cooling capacity.
Homes built on concrete slabs are prime candidates for radiant heating systems and radiant floor cooling takes advantage of the same principle using chilled water.
For the ultimate in efficiency couple radiant cooling with geoexchange systems.
