Don Fugler replied to Damien Greenfield's discussion Is there is cost saving for you in having a tankless water heater?
"That works in Hawaii. Today my rooftop PV modules are under snow. Last week they were under snow. Sometimes they stay covered for 4 months. If they were my hot water system, that would be a long time between showers ... Don"

"The reason I dislike foam in the garage -- even under a layer of sheetrock,  is that owners have the tendencies to puncture the and hang things from the ceiling.  I'm not sure the stats, but after the kitchen, I believe garages are…"

"Dennis, Thanks for the leads. I was the manager of the CMHC research. I recognize that we have established that garage-to-house air movement exists, and that it often brings in polluted air. What I am looking for now is the practical side of air…"

Don Fugler replied to John Brooks's discussion Locating the Neutral Pressure Plane
"Bud, CMHC tested the flow vs. pressure performance of a Saskatchewan loop back in 1987. The report is likely still around but essentially the looping just reduced the flow rate compared to a straight inlet, by introducing a 180 degree turn. The test…"

Don Fugler replied to John Brooks's discussion Locating the Neutral Pressure Plane
"The NPP testing that I did was in the early eighties. We simply measured the cross-wall pressures through any wall orifice or opening we could find, and then graphed the pressure differences against height to find the P=0 intersection. On a calm…"

Don Fugler replied to John Brooks's discussion Locating the Neutral Pressure Plane
"As someone said, the easiest way to check for neutral pressure plane is with a smoke stick on a calm day. Crack a casement window or door, run the smoke up the small crack. Does the smoke come in or go out? Sometimes you see the NPP within the…"
