   John-
   An average cost of radiant in gypcrete is difficult to say. All of it comes down to the heat loss, zoning, controls.......

   For a guestimate in gypcrete radiant system can be approximately $2 sq. ft. for a total system including pipe, fittings, controls, thermostats, circulators....everything you need up to the boiler.
   Check with some of the Radiant Manufacturers, they will typically do design for you if you supply them with a blueprint.check out these guys http://www.radiant-tech.com.

   As for the gypcrete section of your project, I have heard numbers from $1.50-$5.00 sq. ft.

   I am in the process of desiging a house w/about 2400 sq ft. what's the cost to install radiant heat on the main and upper floor, plus the basement slab. Is there a cost per sq ft that can be used for the slab, and then for the gypsum floor, less the cost of the heat source. Mainly interested in the cost of just the tubing w/ the gypsum overpour.

   I just received a couple bids on a radiant heat system for my new home from 2 local installers. The tubing cost alone was about $1.75-$2 per square foot (whether in a slab or gypcrete). The cost for gypcrete was $3.54 per square foot. I found that adding additional zones was expensive ($400-500 each) so I reduced my zones from 7 to 3. The installers also wanted to use a boiler and an indirect water heater (for the domestic hot water). I talked them into using either a Polaris or a Voyager water heater for both the radiant heat and domestic water and saved almost half the cost of the power plants. E-mail me if you have any queastions.
