Which size cartridge heater do I need?
For optimal performance and to maximise the lifespan of your Cartridge Heater, it’s paramount that you choose the correct size. Your heater needs to fit neatly in the dedicated space. This will help minimise air gaps and allow heat to dissipate. Effective heat dissipation greatly reduces the chance of overheating or your heater becoming defective prematurely.

Can Cartridge Heaters be used to heat liquids?
When heating liquids, Cartridge Heaters are not typically suitable as they do not offer a heat transfer that is quick enough, resulting in the heater overheating or liquid quickly evaporating and boiling.
