ELI5 Why do we have to wait for hot water out of a tap?
Why cant no water come out until the waters hot feels like i waste so much water just waiting for it to warm up is there not a world where you turn the tap on and hot water comes out? I dont mind if it takes 30 seconds or so to start. Or is it a cost factor we could do it but its just to pricey?
