here is my plan

  1. 6 zones
    1. 2 - 200 FOOT RUNS OF 1/2 PEX IN CONCRETE SLAB BASEMENT
    2. 5 - 100 FOOT RUNS OF 1/2 PEX IN JOISTS 3/4 HARDWOOD MAIN LIVING
    3. 2 - 100 FOOT RUNS OF 1/2 PEX IN JOISTS CERAMIC TILE KITCHEN / ENTERANCE WAY
    4. 2 - 100 FOOT RUNS OF 1/2 PEX IN JOISTS 3/4 HARDWOOD SPARE BEDROOM
    5. 1 HEAT EXCHANGER LOOP FOR EXTERIOR RUN TO 1000 SQ FT GARAGE
    6. 1 BASEBOARDDS FOR MASTER BEDROOM AS NO ACCESS FOR IN FLOOR

 

  1. 120 GALLONS OF 125 DEGREE HOT WATER FROM GEO THERMAL HEAT SOURCE
  • with the above mentioned design what kind of pump arranghement would be best? a pump per zone or one or two pumps on the manifold header?
  • i would like to control each zone on a floor temperature sensor and have them timed with respect to the time of day. i would think also that the thermostat would turn on the pumps? any web sites or products to recomend?
  • With the loops / zones as mentioned what would my flow rates be? approximately i heard a 1/2 inch pex is about 1 gallon a minute max? can i use this to size my pump
  • air purge? some zones above and some zones below the manifold
  • heat exchanger zone - did this so i would not need to glycol the entire system
    • how does this loop work. i think i need to have a presure vessle?
    • water to air heat exchanger would also be needed in garage. any good sources out there?
    • i have four 1/2 pex running to the garage for flow on the secondary of heat exchanger
    • how much heat lose will i have in the 30 feet running to the garage. i was unable to get below the frost line
  • in the bedroom i mention baseboard heaters. will they function with 125 degree water and is there a recomended type / website?
  • the patern shown to me to do this involves no joist drilling. hard to explain but basically yhr main feeds run down the center beam and go up into the joists and out at the beam?? if the drawing is attached then you might understand

each time i try to attach the drawings it locks up??????
