Smart Meter gives delayed readings? + Cost of running electric fan heater?

That's not how it works. It's the IR component of sunlight that carries heat.
Correct, there is no heat value in UV, assuming John really intended to type UV rather than IR. The graph, posted earlier, clearly shows a wide spectrum of IR passing through glass.

Eh? I did, indeed, intend to type UV.

There is more energy (which manifests as heat when absorbed by things) in the shorter-wavelength UV than in the longer-wavelength IR.

... unless, that is, physics has changed in the decades since I was at school and uni ;)

Kind Regards, John
