In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
Looked at a radiant slab install for a customer last week. The customer had radiant installed in another building using a different contractor. ( I spent two days redoing that so it was done properly) I had my wholesaler do a heat loss for the new building slab and it just seems off. Might be I have not done a floor in a long time.
40x40 building with a first floor that is 2x6 construction. The slab is basically the basement with the foundation being half above grade and half below. There are two 12x13 roll up doors and a steel entry door. The 8' foundation walls that are below grade are not insulated. 4' slab, 13'6" height to heated first floor ceiling.
Wholesaler came up with 12 loops of 1/2" tubing @ 200' loop lengths.
Designed for 115 water temp at 0 degree design temp.
Maybe I am just off but it seems like a lot of tubing?
