I wonder why folks fear to use their real names?
Did you learn this at another forum?

Interested Onlooker (for instance)
I have read many,many good comments by you and others.
Why do you fear to use your name?

What is the WORST that could happen?

I have never heard of anything "bad" happening to anyone for posting their name.
I don't get it.

Are you afraid that Robert or Steve plan to "poke you in the eye"?
(smiley face)

Or Perhaps you will explode?

I think there is something unfriendly about not sharing your name.

In another thread, my choice for HVAC was appropriately questioned. The system seems inordinately complex, costly, and convoluted. At least, on the surface. But digging deeper, the reasoning behind the design becomes clear. But, does that make it right? Is this the best HVAC design, or is it redundant and wasteful?

Here are the pertinents:
• Climate Zone 6
• 2700 sq. ft. finished space in story-and-a-half (bungalow style) house
• 2000 sq. ft. unfinished basement (future completion for aging parents)
• 4 Bdrm, 3 ½ bath house
• Tight, highly insulated home

I am replacing a 30 year old plastic bubble skylight as part of a major remodel. The skylight is located a flat (low slope) roof in a typical Chicago small residential building and serves a third floor bathroom. The skylight will not be openable.

I have searched this site, the web, and the manufacturer's installation information, but am still unsure how to orient the skylight to maximize its benefits, while reducing drawbacks, like unwanted heat in Summer. It appears that the only requirement is that the skylight be installed at a slope greater than 15 degrees.

I am renovating my house, installing solar panels and getting rid of my gas forced hot air system and replacing with mini-splits (very small home < 1000 sq feet)
I would like to install an energy efficient heating system in the bathroom (about 6' x 8') as I'm not sure the heat will effectively get there, plus I like to have a separate zone for the bath for the usual reasons. i had thought about electric radiant heat in the floor but have heard that can be quite an energy drain.
Do people have a suggestion for a very small heating unit for this purpose?
Thanks!
Maggie

We are looking at insulating an older home that has poor insulation (original part of the house 1850, additions in 1970) and are tempted by this Tripolymer product. The owner of the company claims that it is a 'green' product with no health risks. I can't find any information to the contrary as all the sites I'm coming up with are sponsored by foam companies. Do you have any information on the potential downside of this foam insulation? (PS: CL&P, our electric supplier is offering a $1 per foot cash back for insulating older homes, so there is a significant savings to us if we do it).
