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…"

"John,  of the byproducts listed,  the CO, NOx and H2O I suspect are the most important to consider.   For the unvented heaters used in a cold dry climate during the winter time -- probably adds just a portion of the H2O that would be…"
