Today, I washed my hands at the kitchen sink while making lunch, and was unexpectedly chastised by my partner because she had just started the dishwasher. Apparently, she has recently come across something that has convinced her that running the hot water in your sink means the water that enters your dishwasher will be hotter (checks out), and thus the dishes will be cleaner. I tried searching startpage to see if this is real, but I couldn’t make it through even one llm-slop-ticle about it before my eyes rolled back into my head, so here I am asking y’all: chat, is this real? Doesn’t my dishwasher have a heating element? Is there any meaningful difference between heating the water with a hot water heater vs a dishwasher, other than I can’t use my sink while the dishwasher is filling and I have to pour a bunch of cool water down the drain?
The water heaters are usually gas here though, so electric system doesn’t really matter. Tankless heaters have become a lot more common over past decade or two, both gas and electric. For electric ones you just use a 240V circuit. Most electric appliances that need a lot of power run on 240V here, 30A and even 50A or 60A circuits are common and provide enough power for household needs.
