I am about to pull the trigger on having a 5.9kW system put on our home/office, but honestly PV systems are kind of outside of my realm of expertise (I mostly work within air sealing and insulation…Continue
In this group, members share an array of images from the field, showing the kinds of issues encountered by home performance professionals in real homes. Each tells a story of how hidden (but fixable) problems in homes can cause high energy bills.
"I think Sean is onto the answer. The blotchyness makes me think they may have used a spray can primer like "Killz" in a can to cover water damage or mold. If they shot it on there thick enough it could create a thermal difference.
This is anecdotal, but the people I talk to on the tech support line that are using unvented heaters and gas logs are using it, or installing it, because they were sold on the "100% efficient heating" pitch. Starting a bonfire in…"
"In 2009 I sat in on a ACI conference session in Kansas City with Paul Franscisco who had just finished a study on un-vented gas heaters. It was a 3 year study conducted by Univ of IL Urbana/Champaign about the indoor air quality effects of unvented…"
"Steve, Chimney dampness is a much bigger problem in the UK than it is in the US. It is because of the weather difference and the chimney structural differences combined. But you are correct that you do not want to trap moisture inside of a chimney…"
"In existing homes I have not seen the outside air intakes executed very well. Most times they are without dampers. Worse yet, in prefab fireplace configurations they terminate inside chimney chases instead of outside. So they just end up being…"
"I think the number of chimney draft excluding products is a testimony to what a problem the fireplace can be with the efforts to make a home more efficient and also meet the demands of the homeowner.
Here is a list of the products out there right…"

"I am sorry I didn't see this earlier Mark. I am sure by now you have found a solution since you posted this question back on Nov 11.
However, I was going to mention to you that I have seen a 9x15 Chimney Balloon as a boot plug in a pinch. It is…"
"I know a PV Solar installer that gives a $1K kickback to any customer of his that refers a new customer to him that results in a signed install contract. That is a pretty generous kickback, but it incentivizes the heck out of his current clients. If…"
Are you looking for someone to buy out your idea, or to manufacture and market it and give you a royalty kickback as they build the brand? I might know a guy that can show you the way to the latter.
If you don't mind me asking...why…"
"There are basically 3 types of puffers:
1) The acid variety that you are already familiar with. As you said already they are made by www.retrotec.com (makes the big brown one) and TT Puffer (makes the little white one) but be careful with…"
