I recently ran across a situation where a 40 gallon electric water heater was cycling on and off every five minutes or so. While monitoring that circuit, it would kick on for 4-5 minutes and then…Continue

I searched and searched and searched yesterday for an answer to the question "Does altitude affect AFUE?" but did not come up with any definitive answers. Hopefully this discussion will answer that…Continue

Tom Mallard replied to Rodney Fox's discussion Radon: Truth vs. Myth
"Yeah, it's all a mess, eh? Thus consider it's due to the floor not being airtight, mainly at the edges is the fundamental. So if having to do the work consider adding insulation board below the joists and caulk it to become a vapor barrier…"

"Tightening the crawlspace would increase the negative pressure in the living area, further exacerbating the problem of woodstove backdrafting. Although I imagine it would also remove more toxins from the crawlspace, further reducing the radon…"

Greg Labbe replied to Rodney Fox's discussion Radon: Truth vs. Myth
"Rod, Is it possible to make the crawlspace more air tight? If the crawl was more air tight, it would require less air volume to keep it at a negative pressure relative to the conditioned volume I suspect. Less air volume, smaller fan? What do you…"

Richard Beyer replied to Rodney Fox's discussion Radon: Truth vs. Myth
"Tom, My point is countertop sealer's do not stop radon release. By design they are not designed to do so. For a sealer to fully seal off the breath-ability of a granite surface would cause the material to spall and fail.   Radon is a…"

Tom Mallard replied to Rodney Fox's discussion Radon: Truth vs. Myth
"Yeah, this all has a history, yet today if it's sealed as most are with a food-contact rated finish the odds are very low for the radon to get into the air. Air is how it's deadly able to stick to your lungs, otherwise it's emitting…"

Richard Beyer replied to Rodney Fox's discussion Radon: Truth vs. Myth
"Tom Mallard, Sealing a granite countertop does not slow down radon emissions if in fact the countertop your describing is a true radon emitting granite. Most are not, because they are not true granite. Countertop sealers are designed and recommended…"
