Claim Text:
1. A domestic appliance comprising: a thermoelectric heat pump; at least one series of Peltier elements operationally associated with the heat pump and driven by a supply voltage for producing heat during appliance operation along a first heat flow path directly from a hot side of the Peltier elements through a series of pipes to a primary target adapted to make use of the heat, wherein the resistance of the Peltier elements increases with increasing temperature, and wherein a threshold temperature for the Peltier elements is defined; and a second heat flow path, separate from the first heat flow path that heats the primary target on the hot side of the Peltier elements to directly dissipate a portion of the heat produced by the Peltier elements to environment, the second heat flow path extending directly from said hot side of the series of Peltier elements to remove heat from the appliance such that the heat of the second heat flow path bypasses and does not enter the first heat flow path, wherein at a maximum temperature of the Peltier elements above a normal operating temperature and below the threshold temperature, the power of the heat dissipated through the second heat flow path is substantially equal to the electrical power drawn by the Peltier elements from the supply voltage.
