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
"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.
"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…"
"Marco, The trouble with the Lock top and Lymance or any top seal damper, is that when you bottle a chimney at the top and leave it open at the bottom, you still leave room for cold air to enter the home through the firebox. Basically the chimney is…"
"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…"
A group where energy professionals can learn about all the different energy saving aspects of RCCs. I have worked with one particular RCC for 30 years. I have amassed alot of information I can share. Everyone knows, accepts and understands how RCCs work as a 'Cool Roof' coating. However, that seems to be where the knowledge on these products different energy saving applications abruptly stops. I hope to change that with this group. There are over 300 protective coatings out there and they…See More

I do have a freezer that is about 15 yrs old in the garage. I know it is my "low hanging fruit" to all of my consumption. I keep it because I garden and hunt and I keep it full with the fruits of that labor. I have measured it…"
"Thank you James,
I may be able to get some EFSH readings from my installer of similar 6 kWh installs they have done. Granted the numbers wont match exactly because every install is different, but I can see how calculating the EFSH gives true apples…"
