Cameron Millard replied to Carly@AirCycler's discussion The (Small) Cost of Ventilation Without Recovery
"Thanks for taking the time to address my points.  I will run your calculator and see what it comes up with.  Intermittent ventilation within a set time period like 3 hours can indeed be a reasonable way to bring in fresh air.  I…"

Cameron Millard replied to Carly@AirCycler's discussion The (Small) Cost of Ventilation Without Recovery
"While bringing in outside air can certainly work, I think there are some very important caveats to consider. Cost isn't the only reason mechanical ventilation with recovery is superior.  In newer, very tight homes, the increase in positive…"

Cameron Millard replied to Roy Sakamoto's discussion Whole house air leakage
"Air sealing can also provide an opportunity to reduce contamination from dirty attics and crawlspaces though, but you are right that ventilation is key which is why I think crawlspace fans are a good idea. "

Cameron Millard replied to Roy Sakamoto's discussion Whole house air leakage
"This jives with my experience trying to air seal a very small house - lots of caulk and foam and not much of a result (only a few hundred CFM after several hours of work).  Bigger homes seem easier to reduce in my experience."

Cameron Millard replied to Roy Sakamoto's discussion Whole house air leakage
"Roy, I have not tested for humidity post-retrofit, but that isn't a bad idea. I do know the crawlspace fan works to dry out the crawlspace; we had a client with a flooded basement and installed a vent fan which dried it right up in a few…"

Bob Blanchette commented on Cameron Millard's blog post 90% AFUE Wall Mount Furnace
"Don't forget you have to deal with condensate removal on a 90% heater. Could be an issue for retrofit installations."

Cameron Millard replied to Roy Sakamoto's discussion Whole house air leakage
"I've tackled quite a few air sealing projects on homes built in the 1800's in the Colorado Rockies.  They can be quite a challenge to air seal, even at the 10% required by our utility for rebate funds.  If the crawlspace is…"

Cameron Millard commented on Cameron Millard's blog post 90% AFUE Wall Mount Furnace
"Bob, we administer rebate funds to help people overcome payback costs for upgrades.  Agreed that 10% isn't that big of a difference; hence my dilema in supporting something like this.  I have given out rebate funds for 80% AFUE…"

Bob Blanchette commented on Cameron Millard's blog post 90% AFUE Wall Mount Furnace
"I replaced my own 80% with a 90% furnace last fall, made no noticeable difference in the gas bill. The payback time for going from 80% to 90% just isn't there unless you can buy the 90% for cheap."

Cameron Millard commented on Cameron Millard's blog post 90% AFUE Wall Mount Furnace
"Bob, price point is similar to a small furnace but without installation costs associated with duct runs.  I like your idea of installing a small furnace with registers off the plenum feeding several rooms; my building science mentor did…"

Norman Bair commented on Cameron Millard's blog post 90% AFUE Wall Mount Furnace
"Wisconsin's weatherization program replaces space heaters infrequently.  So I am interested in how well these perform.  Our 1900+ Ft2 condo uses the 90% Empire Mantis fireplace for heat.  It was replaced on warranty after three…"

Bob Blanchette commented on Cameron Millard's blog post 90% AFUE Wall Mount Furnace
"There isn't much demand for these. Wall heaters are purchased due to low cost, most will spring for central systems before they will pay to upgrade to a 90% unit. Others buy wall units because they will work in power outages, but the 90%…"

90% AFUE Wall Mount Furnace

I run an energy program in the mountains of Colorado. We have a lot of homes without existing duct work and older style wall-mounted furnaces. I've been looking for a decent upgrade choice for my clients - so far Rinnai seems to be the brand of choice for most heating contractors.  Problem is they have an AFUE of only .82 at the max, so don't qualify for high-efficiency furnace rebates through our program.  I recently discovered the Energy Saver 90 Plus from Empire Heating, a direct-vent wall…See More
