Frequently Asked Questions
- What is the safest way to use an immersion heater with a thermostat?
Always submerge the heating element fully, use a model with auto shut-off and dry-burn protection, and plug into a grounded outlet.
- Can I use an immersion heater for hot water in a plastic tub?
Yes, if the unit has a stainless steel guard and is rated for use with plastic containers, and you follow the submersion and safety guidelines.
