When the temperature drops below a certain temperature, the immersion heater switches back on again.
Correspondingly, can I leave immersion on all the time?
Do not leave your immersion heater running all the time. No matter how well-insulated the immersion tank is, it will still lose heat and the drop in water temperature will cause the immersion heater to run repeatedly (like your kettle coming back to the boil over and over again).
Can immersion heater be used in plastic bucket?
Do not use an immersion water heater rod in an iron bucket to heat water. Use a plastic bucket while heating the water. Apart from this, do not keep the rod in the bucket for hours while heating the water. Doing so may melt the plastic of the bucket.
Can we boil drinking water with immersion rod?
It is better to avoid using an immersion rod, if you have other means of boiling water. The rod or metal part that you immerse in the water is made of alumium, which can “leach” into the water.

Can we drink water from water heater?
Although water from a water heater is considered safe to drink, consider purifying or filtering it before drinking. Although it’s probably fine to drink water from the heater during an emergency, it’s best to be on the safe side. You can purify water by boiling it or using iodine or bleach in very small quantities.
Can you leave an immersion heater on all the time?
Do not leave your immersion heater running all the time. No matter how well-insulated the immersion tank is, it will still lose heat and the drop in water temperature will cause the immersion heater to run repeatedly (like your kettle coming back to the boil over and over again).
