Pricing radiant job for slab house, 1 level,se exposed wall is all glass floor to roof. Will be quoting mod/con heater w/ odt. But if we use stats in the 3 zones will that control the rooms comfort or run off of odt.

    what make is the heater? generally the boiler control (on-board or add-on) will vary the boilers firing/modulation and the stats will control flow to each zone by pump or valve.

    in a perfect system the thermostats would remain continuously on and the odr curve would track the inside temperature.

    this is how i would set up most systems, with the stats not demanding heat but rejecting it. eg: in bedrooms, where you would want a lower temp than say a bath.

    be aware of the \"all glass\" south east room

    both from a heat load, and a passive gain overheat potential. Crunch your numbers.

    HR, house dose sit in trees, but I'm also worried about heat gain.I'm probably going to let the TT run the circ and the heater will most likly be a MC90w/ odt.
