ABSTRACT:
A portable convection heater for removing ice from a side walk including a cart assembly with an axle and a pair wheels rotatably coupled thereto for allowing the pushing of the cart assembly. Further included is a heat blower housing having a heat blower adapted to blow air downwardly upon the receipt of power and a plurality of heating coils coupled below the blower for heating the air passing therethrough upon the receipt of power. For allowing ideal spacing with respect to the ground, the housing is slidably coupled to the cart assembly thus allowing relative vertical movement thereof. Finally, a plurality of control switches are connected to the blower, heating coils, and a power source for selectively providing power thereto.
