Summary:The utility model provides an impeller, fan and gas heater, the impeller includes: the chassis, a plurality of blades, its one end are along the circumference interval on chassis and be and set up annularly on the chassis, and its other end extends to the orientation of keeping away from the chassis, and the blade is including being first prismatic blade and the second prismatic blade of presetting angle alpha and connecting each other, the end connection of the one end on chassis is kept away from with a plurality of blades to the frame, wherein, first prismatic blade extends to the inboard slope on chassis from the outside on chassis on the chassis, and the second prismatic blade extends from the inboard slope on the interior side direction chassis of first prismatic blade, presets anglealpha and is greater than 0 and is lighter than 180. This kind sets up the blade through two straight blades, and the relative arc of prismatic blade, airfoil profile blade, and its structure is simpler, consequently better
