A portable heater assembly includes a fan module, an electrical ignition assembly, a heating apparatus, and an encasement. The encasement supports and houses the fan module, the electrical ignition assembly, and the heating apparatus. The fan module includes a fan, an electric switch, and electrical wiring, the electrical wiring interconnecting the fan, electric switch and a power source. The electric switch activates the fan by forming a closed electrical circuit within the electrical wiring between the power source and the fan. The electrical ignition assembly includes an electrical ignition device, a spark-emitting electrode tip protruding from the electrical ignition device, and an ignition activator connected to the electrical ignition device by an activator connector. The heating apparatus includes a combustion chamber having a catalyst-containing substrate in proximity to the spark-emitting electrode tip, an air-fuel mixer connected to the combustion chamber, and regulator valve assembly connecting the air-fuel mixer to a source of fuel. The air-fuel mixer provides a uniform mixture of fuel and primary air that is ignited by the spark-emitting electrode tip for combustion in the combustion chamber. The use of primary air improves efficiency and reduces the reliance on secondary air. Limiting the proportion of primary air to approximately 15-20% of the stoichiometric mass of air required substantially reduces the emission of hazardous combustion by-products such as carbon monoxide.

A cooler having a beverage dispenser adapted for seating within the cooler. The beverage dispenser is removably arranged in the cooler, either within the main interior compartment of the cooler or in its own compartment and includes a manually operated pump assembly with a rotatable dispensing arm. The cooler may have a one-piece lid or a split lid, with one portion of the split lid covering the main compartment and another portion covering the beverage dispenser. The cooler may also have wheels and a pull handle. The lid may be attached to the cooler with an integral hinge which limits the angle through which the lid may be opened.
