Heat pump water heater selection

My house is all electric in southern California and I plan to replace my electric water heater with a heat pump water heater. The plumbing professionals have little to no experience with these and are basically asking me to pick the water heater and they'll install it. From the research I've done it looks like the best choices include the Stiebel Eltron Accelera 300E and the Rheem Performance Platinum 80 gal. The Rheem is currenly on sale for $1600 at HD while the best price I saw for the Accelera is $2400. I believe my utility has a $250 rebate for the Rheem.

Relatively non-toxic concrete joint filler/sealing material that will last?

I have a failed cove joint in my below-grade level, and need to replace part of the fiber board joint material that exists between the slab and foundation wall. I need it to be a permanent type repair, as it will be difficult to get at the joint after my remodel, and I have radon present in my soil.

Does anyone know of a product that both works well (i.e may have a 20+ year life on concrete, remaining attached and flexible) and isn't highly toxic or classified as a carcinogen?

Does laminate flooring off-gas when heated?

I have a client that was assured by the flooring supplier that the laminate floor they sold them was okay to install over heated surface. The smell is unbarable, thoughts?

Source for rainscreen / rain screen in San Francisco Bay Area

I'm patching (another) rotted stucco wall, anyone know of a San Francisco Bay Area local source for rain screen products. In particular I'm looking for a small quantity of a really thin air gap product. I can spare at least 1/4" (6.35mm) due to thickness of the old siding vs. what's got to go back.

So any recommendations on a good thin product, and something I might be able to pick up this week?

Who has a favorite heat-pump water heater?

We are now underway with our "pretty good" house here in southern Oregon and I am committed to the hybrid heat pump water heater concept for our 2100 sq ft, three generation house. With four adults and a grandchild in the house, I felt that an 80 gallon unit would be desirable. We plan to locate the HPWH in a centrally located laundry room which is just under 700 cubic feet and have plumbed a floor drain into that room for condensate or tank failure (hope NOT). I had been inclined to go with the GE GeoSpring but I have heard a rumor that GE is going to discontinue manufacture.

Plywood recommended for under quartz countertop?

I am helping my sister install her 3/4” quartz countertop this week. I bought 5/8” Cdx for the counter to sit on. She is complaining about the smell of the cdx and that she would like to use something without added formaldehyde because that’s what all her cabinets are .

What would you guys reccomend ? In your experience how long does it take for the smell of cdx (fir) to go away? Is cdx less toxic than other plywood boards ?

I could get some purebond plywood but they only make it 3/4” which I believe will be too thick.

Exposed batt insulation, no dusting

I have (I think) 10 or 11 joist bays in a utility area in my basement. The joist bays are pretty populated with duct runs, power+data, PEX plumbing, etc with some of those running perpendicular across the bottom of the joists, making a hard lid almost impossible. Besides, I like having access to everything in this area (below the kitchen).

However, it's a bit noisy (both ways) whether the kitchen traffic coming down or the utility room (furnace, my 'mini shop') sound going up.

Bug Screens

I am attaching 3" of mineral wool with 1x4 furring strips over siding covered with WRB. Most details I'm finding use a product like Cor-A-Vent SV-5 as a bug screen but this doesn't address the 3" edges of the mineral wool. Can you recommend a solution that addresses the whole assembly? Is fiberglass window screen wrapped across the bottom (including the rain screen gap) durable enough for this application? What is the maximum hole size you would recommend?
