When the Pottstown PA UU church was built, one part of the plan was a sunspace on the south wall, which hasn't been built yet...

The main room is 44'x48'x16' tall. The 48' east and west walls slope in 4' as they rise to 8'. The ceiling has a 4'x48' north-south horizontal strip. The south wall includes 4 sliding glass doors D, each about 6'x8', with no eyebrows for summer shading.

Here's a flattened view from above, viewed in a fixed font like Courier:

I don't think so.

I suspect that the thin wall thickness and material conductances are much higher than the still water film conductances, with a layer of crud on the outside, and the pipe holds 13 gallons of water which can heat well between hot water usage bursts of 13 gallons or less.
