5.) Install "Whisper Quiet" bath exhaust fan and vent through roof.

6.)Install Freon lines to system and waste heat recovery unit; install drain lines.

That's verbatim from his bid.
Here's the Frigidaire system:

And here's the skinny on the Aprilaire stuff:

So. Whatcha think?
 
Yes - that's the type of system I was referring to.

Some thoughts.

1) I feel that by using one big (13) unit to do it all would be asking a bit much when you could use 2 x 10 units. One for control room, one for studios. ask for a price comparison.

2) placing the blower unit above the bathroom would require long duct runs than if you put the blower unit(s) above the control room with access to them through the ceiling in the space between your sliding doors to the verandah.

3) having the blower units above the control room would allow for shorter (cheaper) ducts directly to the the booths, studio and control room.

4) the compressor units could then be placed outside the rear wall of the control room with short pipes up to the ceiling of the control room for the blower units.

Great!
Thanks for the insight, John.
I'll look into the double system, but I have a feeling it'll be cost prohibitive.
 
by comparison the 3 similar units at left bank cost around AUD$12,000 or US$8,000

cheers
