This paper presents a performance investigation of a sensible thermal storage (STS) system for cooking applications. The system consists of a cooker and storage units. The cooker unit supports the pot and the storage unit stores heat from heated Duratherm-630 oil. The system’s thermal performance was tested by cooking beans and boiling water. A 1,800W heating element was used to heat the oil to 220 Â°C. It took 2 hours and 50 minutes to cook beans while charging and 160 minutes to boil 40 litres of water during discharging. The temperature in the storage unit after cooking while discharging process was 120 Â°C. This temperature range can be used to cook other types of food.
