Heating heat exchanger with electric heat emitter

A heat exchanger comprising:

• a heat exchanging core portion having a plurality of tubes arranged in parallel and a plurality of fin members disposed between a pair of adjacent tubes out of said tubes;
• an inlet tank provided at one end of said tubes for distributing hot water into said each tube;
• an outlet tank provided at the other end of said each tube for receiving the hot water;
• an electric heat emitter provided at a predetermined position of said heat exchanging core portion, said electric heat emitter including a positive electrode plate, a negative electrode plate, and a heat emitting element disposed between the positive electrode plate and the negative electrode plate;
• and
• an electric wiring cover attached to said inlet tank or said outlet tank, said electric wiring cover being provided with a positive electrode wiring member and a negative electrode wiring member, wherein
• said positive electrode plate and said negative electrode plate are electrically insulated from said heat exchanging core portion,
• said positive electrode wiring member is connected to said positive electrode plate, and
• said negative electrode wiring member is connected to said negative electrode plate.
