Sure does present a question or 3 ....
Of course it's been done for decades and decades in computer
rooms, but in residential ???? Computer rooms have high velocity and
low humidity ( or problems ! ) !
To do that in residential - and control humidity - you need a
sufficiently cold coil, of course. Thus, cold SA. Which is going to
run through steel and concrete ? Which are then going to try to
approach SA temp ? Under the rug, which is exposed to high humidity
room air ?????
And in this part :
"How does it compare in cost? The cost of AIRFLOOR is the same as a
quality overhead duct system. In some buildings the first cost may be
even less if the savings from eliminating drop ceilings or soffits are
included. Compared to a hot water floor radiant system, AIRFLOOR will
cost less because a hot water radiant system must include an overhead
duct system to provide ventilation"
Hmmm... no cost savings they say in the first sentence,and
then in the next they state something that simply isn't true. Not a
good sales pitch, IMO.
And this :
"6) Inaudible ventilation - since conditioning air is distributed
under the floor, mechanical noises, vibrations and air flow sounds are
reduced to a level below awareness"
Ummm..... bullshit. Assuming proper throw, register noise is
unaffected either way. Noise from the mechanical closet is unaffected
"3) Reduced energy costs - AIRFLOOR will save 20 to 25% on energy
costs due to the efficiency of its heat-transfer and heat-storage
Not buying that one AT ALL !
Put that thing over a wood subfloor above a damp crawlspace and you
would have mold and rot out the Ying-Yang (Ying-Yang, thats a technical
term). It would rain in the crawlspace! It would probably rain in a
basement also! It might work OK on a slab, but I wouldn't try it.
Looks like they will fold when the lawsuits start.
