A heating pump includes an electric motor, a pump housing fixed to the motor, an impeller driven by the motor, and a ring heater with an inner hole for heating fluid in the pump housing. The pump housing has a pump chamber and a pump inlet and a pump outlet which are in fluid communication with the pump chamber. The impeller is received in the pump housing and having an impeller inlet and a plurality of impeller outlets. The ring heater is disposed inside the pump chamber and between the pump inlet and the impeller. The impeller inlet is in fluid communication with the pump inlet via the inner hole.

A coreless permanent motor has a stator and a rotor rotatably mounted to the stator. One of the stator or the rotor has at least one winding disc (). The other one of the stator or the rotor has at least one surface charged magnet disc (). The winding disc () or the magnet disc () is formed by two or more sector shaped units that are mounted to two or more support members () respectively. The winding disc () or the magnet disc () is formed by closing the support member () and the closed support members () form a cylindrical housing. Thus, the structure of the coreless motor is simplified.
