Why does it take so long for hot water to reach distant bathrooms?
Hot water takes several minutes to travel through long pipes from the water heater to distant fixtures, and remote buttons or app controls often fail to speed it up. This delay wastes large amounts of water down the drain and makes everyday showers frustratingly slow to start.
