By filling in the boxes in the water heating time calculator below and clicking the respective "Calculate!" button, you can calculate the power and/or time required to heat particular volumes of water. For the Theory & Explanation, click HERE.
Roughly speaking, due to its density and viscosity, heavy oil will heat up in half the time of water, or if you prefer, require around half the heating power to heat up the same volume as water in the same period of time. However this will require a much lower watt density than on a water heater. For more specific information on oil, or heat up calculations for any other of a very long list of chemicals, please call Jamie on 01827 703228.
When you know how much power you require, your next decision is whether to apply direct heat via a heating element 250w - 6kW
or a screwed immersion heater 1kW - 24kW
or for greater than 24kW, a flanged immersion heater
or perhaps even a vat heater (2-18kW) if you wish to access from the top of the tank.
