Induction Range vs Standard Electrical Range

The ranges I am looking to purchase are either a standard electrical element range or an induction range. The price difference between the 2 ranges is $250

My question is what is the payback or ROI if I get the more expensive $250 induction range? If I use the range 4 times a week. How much less power will the induction range use vs the electrical element range?

Minimum foam thickness for basement floor

I live in zone 5, Western PA and will be finishing part of my basement. I have very little wiggle room to maintain code height for the finished assembly. My plan is to use glued and taped olyiso with two floating layers of 7/16 OSB staggered with a floating floor on top. Can I get away with 1/2" foam and likely avoid summer condensation issues?

And though I don't want to use cork for my basement floor, would this help enough to make up for the cost differences of cork flooring? I could increase the foam thickness to 3/4", but no more.

Any advice would be appreciated.

My wife and I recently bought an old summer home which we are converting to a year round home. The house is about 100 years old and currently has no insulation. My plan is to insulate the basement and attic as soon as possible. I have decided to insulate

The house is also badly in need of a new roof, which I am in the process of doing now. There are some spots where it was leaking and the sheathing is still a bit damp. My insulation strategy being an unvented cathedral ceiling I am guessing it's fairly important I let it dry out before insulating?

I am in Westchester NY my home is stucco no insulation approx 1900sq ft.
5 zones , dhw zone
My question is that the boiler was oversized and therefore cycles constantly, who can help make adjustments to help improve the performance of this system. I am homeownew with hardly any knowledge of how to correct this

Would you build a DIY Powerwall

Fascinating video over on Vice about a few DIYers who are building their own Powerwalls, microgrids, and vehicles using "old" batteries. (https://video.vice.com/en_us/video/motherboard-dear-future-build-diy-pow...) I'm not sure I would have the guts to put a homegrown Powerwall in my garage, however. A utility building in the backyard seems safer to me. Thoughts?

Crawl Insulation--Walls or Floors?

Zone 4, Asheville NC build on a steep slope. Because of the slope, we will have a sub-basement crawl that is as much as 10'-12' on the low side and 2' on the high side. The floor will be dirt with the same slope as the hillside. It will be sealed with 12mil poly. The local energy rater said I could have either the walls insulated, or the floor insulated--it makes no difference. It will have a duct feeding conditioned air to it per code, and a dehumidifier. Basement floors will be quartersawn white oak over advantech.

double ceiling (similar idea to double wall)

can't find any info on this idea.
i'd like to insulate an awkward existing post and beam structure. it has a low-angle metal roof built over the original flat roof with its torch-on membrane still intact. the attic space tapers to nothing at one end, so not enough attic space for insulation above the torch-on layer. inside flat ceiling height is much taller than i need.

wondering if i could build a "double ceiling", similar to a double stud wall, but oriented horizontal instead of vertical?
