Electric coffee maker in which the water is transported from a fresh-water tank through a cold water line to a water heater, and from there through a hot-water line to a coffee filter. The coffee maker has incorporated a valve and a timer, called a time delay valve, which in conjunction with the heater and cold water line holds back or delays the full transport of water from the fresh-water tank and permits no flow of water or only a minimal amount of it to be transported for an initial period of time. This permits liquid ducts and receptacles downstream from the water heater to be preheated and thus smaller amounts of really hot coffee can be taken from coffee makers which are designed for larger quantities of coffee.
