Peltier poor cooling performance

If your Linkam peltier stage is suffering from reduced cooling performance, such as not being able to achieve the cooling rate set, or no longer being able to achieve the lower extremes of its temperature range, the likely cause is a build up of limescale inside the heater restricting the flow of water. 

Try placing some household descaling agent into the water circulator and running this through the stage (without running any cooling or heating profile) for several hours.
