Abstract
A heating system for heating a target fluid may include an intermediate liquid circulation path for holding an intermediate liquid and a target fluid flow path for conveying the target fluid, where the target fluid flow path and the circulation path are separate from one another but thermally communicate with one another via a heat exchanger. The intermediate liquid may be heated by a heater and circulated in the intermediate liquid circulation path by a pump. A ratio of the maximum heat output of the heater to the volume of the intermediate liquid circulation path may be at least about 5 Watts/cm3. The thermal mass of the intermediate liquid may be 0.3 times the thermal mass of the target fluid or less. The heating system may be utilized in a washing appliance such as a dishwasher, where the target fluid is the wash water used in such appliance.
