...We don't...? Who?
- xboxnolifes 3y agoIn the past it was common knowledge not to. It's of much more uncertainty as house plumbing has changed.
- crote 3y agoThat's because it is primarily a historical artifact[0]. Most modern plumbing heats water on-demand, which pretty much entirely avoids the risk of storage tank contamination or Legionella. [0]: https://www.youtube.com/watch?v=HfHgUu_8KgA https://www.youtube.com/watch?v=HfHgUu_8KgA
- mrguyorama 3y ago>Most modern plumbing heats water on-demand Where is this the case? These kind of things are extremely locational and here in the US it seems like 45 gallon hot water tanks are still the norm. We had a fad with "on demand" hot water heating but everyone gave up on it when the "it saves you money" part didn't work so well.
- wkat4242 3y agoHere in Europe the money saving works really well. The issue is that you need a lot of power to heat on demand. Meaning natural gas. Having an electrical connection strong enough to heat water for a shower is rare.
- callalex 3y agoI wouldn’t consider on-demand heaters to be all that modern. Places that use on-demand water heaters are now at a disadvantage because it is much more challenging to switch away from fossil fuels over to electric. Tanks, especially with a heat pump, can provide all the heating a household needs through a standard 120V15A socket. For on demand electric water heating you’re looking at upgrading main panels to supply an additional 240V20A and even that will struggle to heat the water enough in some winter climates.
- Gigachad 3y agoStorage tanks are extremely common in Australia, but they are run hot enough to kill anything and then get mixed with cold water to bring it back to the desired temp.
