Dana, lots to read.... still digesting. I'm definitely looking at high-performance walls. I'm sure I'll have some follow-up questions and I read more...

Dana, I'm not sure if you are still following this thread. On the off chance, I will post.... Sadly, this project took an.... unexpected.... detour. Before I elaborate, let me first say "Thank you"! I implemented several of your suggestions and the benefits were immediately apparent...

Thanks, Dana. You have motivated me to look harder for the borate-only material in my area.

Hmmm. The price of rolls of unfaced R30 seems competitive with the "friendly" version of cellulose. I would still air-seal the attic, but instead of removing the old two layers of R13, I would just run the R30 perpendicularly on top of the roof deck. I suppose I should still put in the...

Dana, I have a confession to make: When you posted those prices for cellulose, well...... I thought you were exaggerating! I've lived in this house 17yrs and only had to go into the attic on four separate occasions. The only thing up there is the air-handler for my A/C. For $260 I get 20 bags...

Wow, that is some detailed documentation. UFT-80 would probably be within my abilities..... with the right friend on speed-dial. I'm pretty sure I could dial back the temperature right now. As it is, at 140 I'm having some serious over-spike during the day. If I beef up the insulation in the...

BTW: On Thursday I'm headed over to CT to see "Wally" to get my polyiso fix.....

I think I can safely say that I will have some percentage of my future heating needs delivered through the heat pumps that replace my ancient A/C unit. Using a chiller like this one for the extra heating capacity (and cushy floor comfort) would be really interesting. If the mini-splits...

Thanks for the tip on the reclaimed foam! It would seem a very cost effective solution for adding significant R-value to the bedroom floor/walls that are exposed to the garage...... a project I could tackle this winter instead of waiting for next year.

I was interested in foaming the attic rafters (and gable ends) because the air-handler of my A/C is in the attic. However.... if I transition to mini-splits this is less of a concern. I have very very little attic space since much of the first floor is "floor-and-a-half" cathedral ceilings...

Very interesting reading, particularly the section on modulation. It was also a pleasant surprise to see heating/cooling measured capacity to be ABOVE the manufacturers reported data..... I have spray insulation going into the attic next year (and around/underneath the bedroom over the...

Could you help me understand why the air-delivery system of a mini-split is so much more efficient (and better capacity it seems) than the heat pumps that deliver through hydronic systems? The same friend that I worked with on the solar also does geothermal....... but the shale on this mountain...

Those are the very same Fujitsu mini-split units my plumber friend is putting in his house this week and lives just slightly northeast of me.... I'll admit I thought he was living on the bleeding edge but this is the third time I've seen those units referenced in the past month. A few other...

Forgot to mention: No "K-Factor" information on my oil bills.

Forgive my poor description in my first post: I did want to imply a primary/secondary loop in the #3 setup. Bah..... Just re-read what I wrote there. I would have been better off taking a picture of my drawings. The primary/secondary loop drives the buffer tank to give stable temps to my...

Dana, Thanks for the detailed response. ZIP: 12514 Using loadcalc dot net: 36k @ 0F 41k @ -10F Unfortunately, my oil usage is hard to calculate: Too many changing variables in the last seven years and I don't have records before that. I have used a wood stove in a wide range from primary...

Moderators: My apologies if I chose the wrong forum. I wasn't quite sure where this one fit. ---------------------------------- For the past fourteen years my radiant heat system, fired by oil heat, has served me well. Unfortunately, despite wonderfully low oil prices, I find myself under...
