An insulated cover for the top of an outdoor patio heater includes a toolless fastening system and multiple layers of material. The upper layer is silicone-coated fiberclass cloth; the lower layer is a high-temperature fiber glass fabric, and those enclose an insulating layer of needle mat. The upper and lower layers are formed into substantially conical shapes using three radial sewing darts that are offset from the center of the layer. The fastening system has three sprung hooks spaced around the underside of the cover to hold the cover on the conical metal top of the heater. The hooks are fixed by lacing anchors to the lower and insulating layers.

An electric heating device includes at least two hollow profile elements which form a fluid channel for a fluid to be heated and, opposite the fluid channel, a heating chamber which is bounded by opposite contact surfaces against which at least one PTC element abuts in a heat-conducting manner. A scalable and easier to assemble electric heating device is achieved by connecting the hollow profile elements to one another by complementary form-fit segments.

An accessory for a patio heater includes a bracket to secure to a pole of the patio heater; two arms attached to and extending away from the bracket in an upward direction; and two concave shields attached to the arms to bend around a heating element of the patio heater; the concave shields reflect heat in a desired direction.

A reflector oven has at least two sets of ventilation holes which double as holes for pan and oven support. The oven may be set for use with either a cookie sheet or similar flat sheet or a muffin tin or similarly constructed pan. Placing support rods through on set of holes allows for one pan while placing them through the other set allows for the other pan.
