And at what water temperature? Are the plates extruded or sheets? Output can be anything between 1 and 30 unless you nail down some other variables.

    room temperature also

    as the delta t between the floor surface and the space temperature drives the output.

    Radiant Engineering has some excellent tables and graphs to show outputs a temperatures and with various floor coverings. www.radiantengineering.com

    Thermofin Output

    Output based on the R-Value of the finished floor and fluid temperature with a 65°F MRT. The gray horizontal line is generally the maximum comfortable output for these conditions.

    Hope this helps.

    That is a very nice webb site,...

    But get the latest design guide from Wirsbro / Uphonor or whatever their name is...it's a simple question with a complicated answer. Some jobs we just kept adding tubing untill the customer was happy and why does each joist bay only have one run of tubing in it? That may be a problem!
