Water heater for geothermal system?

I currently have a geothermal system approximately 10 years old. I have two electric water heaters. My water heater in the attic is going out. It is a standard 50 gallon electric water heater ( replacement size does matter, as it must fit through the attic opening.) It is not hooked up properly to allow the geothermal system to heat the water during the allowable times of year. Is there a particular water heater (brand and model) you would recommend that can be connected to the geothermal system (assuming it is done properly this time) ?

Thank you.

Weatherizing home

We have an attic with about 12 inches of blown-in fiberglass. The area is about 815 sq ft. I plan on having the attic air sealed and more insulation added. One contractor wants to add about 12" of blown-in fiberglass and the other one is recommending about 12" of blown-in cellulose. I believe the cellulose is the best option but worried about weight on the ceiling and the reduction in R value of the fiberglass once it is compressed by the cellulose. How much R value to you think I will lose in the fiberglass?

Low slope residential roof vent question

Climate zone 7, lots of snow (high rockies)

Is it worth venting over the top of the sheathing to prevent ice damming on a 60' long metal roof with a pitch of .75"/12" ?

The assembly, as it currently stands, inside to out:
1_Gypboard ceiling
2_11 7/8" TJI perpendicular to long low slope w/ R-55 closed cell spray foam.
3_1/2" Foam thermal break between sheathing and TJI upper flange.
4_roof sheathing.
5_roof underlayment
6_VENT SPACE???
7_Floating metal roof (for thermal expansion)

Sweating windows

What would cause my windows and doors to sweat when it gets cold out if the indoor humidity is low? They are new windows and doors. The windows freeze shut when it gets about 10 degrees and the door handles freeze as well. I don't know the exact indoor humidity, but I can tell you it is low by how dry my skin and nose are in the morning. I keep the indoor temp about 65 to 70. Can anyone explain the problem and how to fix?

Is bubble wrap duct insulation non-toxic?

I have an exposed duct in the utility room that just got repaired and wrapped with foil bubble wrap. There is now the smell of off-gassing plastic. Is that safe? What is the alternative?

Follow-up on reinsulating attic floor

Back in 2010 I wrote in and received some good guidance from " Riversong. " We were considering reinsulating the attic floor. As a follow-up i thought that I would report the results. We had an insulation company remove the fiberglass from the attic floor and fill the cavities with Demilec Agribalance open-cell foam. In the main area of the floor the 2" X 6' cavities are filled and then covered with 7/16 osb. The " outer " areas without flooring have up to 9 or 10 inches of foam. They installed baffles to protect the soffit openings.

Moisture between underlayment, plywood, and metal roof

We're building a sunroom addition, nuts to do this in winter, especially this winter in the Atlanta area, but so it is. I'm doing a lot of the work myself, help from a metal roofer with other skills. This contractor wasn't finished framing a 1.5/12 shed roof dying into a 5/12 roof, waiting to sort out a particular issue, but went on to place 1/2 plywood, Rhino underlayment, then 24 gauge 1.5" standing mechanical seam metal roof panels. The underlayment running out the top runs a couple feet, was tucked under asphalt shingles from garage roof, a couple screws thrown in to keep it down.

Why are refrigerator coils not mounted outside of our homes?

Wouldn't it be more efficient to exhaust hot air outside in summer like an air conditioner? And in winter why isn't cold air from the outside used to maintain fridge and freezer temperatures? Thanks!
