John Proctor replied to Kent Kjellgren's discussion Sealed crawl space for new construction
"With respect to the delivery temperature into the crawlspace, the supply air would be at 45 degrees or less while the house air would be at house temperature 75 degrees or more. If the depressurized house is a potential mold problem, then I would…"

"Kent  -- the best version I have seen of this includes: A low wattage fan low flow such as a Panasonic running constantly exhausting crawlspace air to outside.This pulls low relative humidity air from the house into the crawlspace in the winter…"

"Mark -- you are right I should not have said never. The only walls that I have seen that do not leak to the exterior are houses built with airtight drywall. Since you have not seen leakage from interior walls I wonder why you seal at the top…"

"Since the specification you are quoting (?) specifies ventilation system and all interior doors closed and with reference to outside, one can would deduce it is there to test for an imbalance in flows from the ventilation system. If it across the…"

John Proctor replied to Tray Biasiolli's discussion Two-stage furnace, control at furnace or thermostat?
"Ted -- The startup losses on modern furnaces are much smaller than the old days. I would suggest a modification to your statement to: "if the ducts are normal and in unconditioned space then the losses exceed the gains from long run…"

John Proctor replied to Tray Biasiolli's discussion Two-stage furnace, control at furnace or thermostat?
"I hate to be the one to bring this up, but two stage furnaces are quite capable of having lower installed efficiency than single stage furnaces with the same max input. This comes from two sources: 1) the fuel air mixture on low fire often has too…"

"Dennis, combustion appliances do not put out any specific amount or range of CO (or CO/Hr). A very small amount (in the single digits) of CO may be given off with a new appliance, but it is often after they have operated for a while that the CO…"
