Abstract: A heating and cooling system, particularly for water, provides advantages in safety, reliability and efficiency of temperature regulation systems for liquids. A temperature regulation unit is controlled by a controlling device. A sensing unit is relied upon to detect a particular liquid temperature and a safety unit enables the temperature regulation unit to be disabled. A reset device connectable to a power source via a transforming unit is adapted to lower the voltage level of the power source to a level safe for use by a user. The reset device is operable to reset the safety unit, thus enabling a controller unit to again operate the temperate regulation unit. In a preferred embodiment, the controller unit operates the temperature regulation unit through the safety unit, such that when the safety unit is activated, power cannot be transferred to the temperature regulation unit.

Abstract: A liquid temperature regulation system comprises a controller means adapted to control operation of a temperature regulation means. A sensing means to detect the liquid temperature and a safety means to enable the temperature regulation means to be disabled are operatively connected to a reset means that is connected to a power source via a transforming means that is itself adapted to lower the voltage level of the power source to a level safe for use by a user. The reset means is operable to reset the safety means, thus enabling the controller means to again operate the temperature regulation means. A water storage system delivers liquid at operating temperatures at a preset time, such system including a liquid storage means, a temperature regulation means, a temperature sensor to sense the temperature of the liquid in the storage means, and a controller to control the operation of the temperature regulation means in accordance with a temperature sensed by a temperature sensor.
