Is there an electric system that can heat water for radiant floor heat, domestic hot water and air conditioning?

I am constructing a new 1000 sq.ft single story with 6' crawl space. Two bedroom, 1 1/2 bath cottage. I would like to have electric solar panels on the roof to offset 90 - 95% of the load. Does this sound doable? I have unobstructed S SE exposure and can fit approx. 20 panels on the roof. This is on Long Island New York

Thank You
Mike

Spray foam insulation

We will be building a new house this spring and are concerned about using closed cell spray foam insulation as spec-ed by our architect due to potential health risks. Even though the manufacturers say it is non-toxic and safe, there seem to be many people out there who have found otherwise.

Can anyone recommend a product that is safe to use, non-toxic and affordable?

R-value of high density urethane?

Anybody know the approximate r-value/inch for high density urethane (HDU) board? This is the stuff used for sign board or other carving. I've found it in densities between 10-30lb/cf., in blocks, sheets, etc. It can be readily machined, glued and is waterproof. I used to use it for product design prototyping years ago. I don't think it is typically used for insulation which may explain why I can't find any r-data on it. I was thinking it might serve well for door cores or rigid thermal break applications.

Thanks in advance.

Salutations! I am building an aquaponics greenhouse and am wondering what anti-mold/anti-fungal to use?

I am building a greenhouse to house an aquaponics system in a northwest climate, and am wanting to use as environmentally friendly anti-mold as possible.

Thank you sincerely, much gratitude.
