[OT/Pedantry] The shower faucet thing is caused by a large distance between the spigot (where the hot/cold mixing happens) and the shower head, not between the water heater and spigot.
- tunesmith 12y agothanks, I'm better at systems thinking than plumbing. :)
- tjradcliffe 12y ago[Pedantry^2] Both effects are important on different timescales. When first starting a shower, the distance between the hot water tank and the spigot is what matters, and this tends to produce a long-period oscillation that manifests as just a single over-shoot at the start. Then there is a short-period oscillation due to the tap/spigot distance. The initial transient is still technically an "oscillation" in the sense it is described by the same mathematics, even though it's a one-off.
