Abstract
Embodiments of the present invention provide a hot water dispenser capable of heating water to near boiling temperatures (e.g., 205° F. to 212° F.). When water at near boiling temperatures is required, a secondary heating element is activated. The secondary heating element is in thermally coupled to the dispensing tube so that the water in the tube may be further heated as it passes through the dispensing tube from the tank to the dispensing outlet. Heating the water to near boiling just prior to its being dispensed reduces energy costs because the near boiling temperature water is not stored and allowed to cool. Additionally, the need for expensive insulation or expensive thermostats is eliminated.

A hot water dispenser capable of dispensing water of a second temperature from a faucet, comprising:
- a water tank capable of holding water and having a first heating element for heating the water to a first temperature;
- a tube coupled to the water in the water tank for transmitting the water from the water tank to the faucet;
- and
- a secondary heating element coupled to the tube for heating the water from the first temperature to the second temperature.
A hot water dispenser for dispensing water of a second temperature from a faucet, comprising:
- a water tank capable of holding water and having a first heating element for heating the water to a first temperature;
- a tube coupled to the water in the water tank for transmitting the water from the water tank to the faucet;
- and
- a means coupled to the tube for heating the water from the first temperature to the second temperature.
A method for dispensing water of a second temperature from a faucet, comprising:
- heating water in a water tank to a first temperature;
- transmitting the water through a tube from the water in the water tank to the faucet;
- and
- heating the transmitted water within the tube to a second temperature.
