Purchasing electric food warmer trays gives the buyer the ability to keep food hot and moist during any hosted event without paying additional per event fees. Renting warmer trays allows the host to obtain the heating necessary for a specific occasion without taking responsibility for equipment performance.
Often, electric food warmer trays are rented from the company hired for catering a specific event. This means that the staff assigned to prepare the food will be familiar with operating the warmer tray. Since warmers can come in either electric, gas, candle or steam models, there is some variability in operating the device. Renting equipment from the catering company ensures that staff will be able to successfully operate the equipment without additional assistance.
Renting is also advantageous if the equipment somehow malfunctions. When a company is responsible for the upkeep of the device, any performance problems automatically become the responsibility of the company.
Owning food warming trays also has its own advantages, however. If the owner regularly hosts events well suited to food warming trays, it can be more economic for the host to purchase the equipment. This reduces the total cost of each event. The owner can also become familiar with the operation of the equipment ensuring fast and fluid performance.
