Oil heating calculator

Calculate how long it will take to heat a batch of oil.

The supplied values for Specific Heat Capacity and Density are for Rapeseed oil.

Inevitably this calculator gives the "best case" time, heat loss through insulation, presence of water in the oil, thermostat cycling during heating and voltage loss down extension cables will all contribute to increasing the time taken or power consumed.
