Hello, I'v been an industrial electrician for 32 years and done instrumentation. I've got a homemade deal for the summer (copper piping under a insulglass patio door) right now heating a 60 gallon tank, if i buy a 30 tube unit, rack to put it on, 50 feet of tubing, connectors, crimper, heat exchanger, drill pump, circulation controller. what else do i need in the primary circuit, eg. expansion tank, relief valve?
I want to preheat my hot water and run a water to air heater in the plenum of my furnace.
my house is a one story ranch style, with bungalow roof 1200sq. ft., on coldest windy day in the winter it might drop 8 degrees Celsius. My furnace is hi efficiancy 75.000 btu.
Q. does your insulated tubing have both tubes in the same insulation with the wire or is it single tube and single conductor
Q.does the rack screw or bolt directly through the asphalt shingles?
Q. I live in southern Ontario (just south of Hamilton) what angle should it be? roof is (1 rise, 3 run)
Q. what does it take to add another 30 tubes to the system at a later date would it be in series or parallel with the first 30, and i"m thinking, if i 60 tubes don't heat my house, i might go to 90-120 tubes?
Q. AM i correct, that the new yellow automotive antifreeze will work ?
Q. how do i fill it, with glycol and water. with and without a drill pump/\?
I'd like to order, and get started , but this is all new to me, so a little help would be so appreciated.
p.s. did i forget anything? Sincerely your Heikki
