Immersion heaters are NOT suitable for liquid heating in standard drinking cups due to critical operational constraints and safety considerations Immersion depth non-compliance – Cup dimensions typically fail to meet the manufacturer-specified minimum submersion thresholds (≥200mm vertical depth) Our heater is 10 inches, we require the heater to be completely submerged in water for useMaterial compatibility risks – Glass/ceramic cups lack the thermal shock resistance required for sustained heating cycles, with fracture risks escalating at temperatures exceeding 60°C The HeavenBird heater CANNOT be used with people/animals in the water, please wait until the water is heated before using. We strongly recommend NOT using any heaters in animal feeders. Our heater is ONLY SUITABLE for heating containers with a fixed water volume, or with automatic water filling function. The frequency of cleaning scale on heating rods depends on several factors, including local water quality and frequency of use of water heaters.Local Water Quality: If the water quality is good and scale formation is slow, cleaning once a year is sufficient. If the water quality is poor and scale formation is fast, it is recommended to clean it every six months.Usage Frequency: If the water heater is used frequently, the heating rod accumulates scale faster. In such cases, it is recommended to clean it every six months. If the frequency of use is low, once a year is adequate for cleaning.In conclusion, the cleaning frequency of the scale on the heating rod should be adjusted based on the specific circumstances. Regularly cleaning the scale on the heating rod is important for ensuring the normal operation of the water heater, prolonging its service life, and improving the quality of hot water.After using for a period of time, we recommend soaking the heater in baking soda or white vinegar to remove dirt through its chemical reaction with scale. Step: 1). Boil a pot of boiling water and pour in citric acid or baking soda. Step: 2). After the citric acid or baking soda is fully dissolved, put it in a heating rod and soak it completely in the water. Step: 3). Wait for 10 minutes, then clean with a cloth. Safety Guidelines for Electrical Immersion Water Heater - Read the instructions carefully before you use the HeavenBird immersion water heater. Q: Is this heater safe? Could it damage my container? A: Electrical heating equipment requires strict adherence to operational protocols. Key safety considerations include: Immersion compliance – Ensure complete submersion during use to prevent dry-fire hazards Pre-operation verification – Thoroughly review technical parameters in the user manual prior to activation Operational discipline – Follow manufacturer-recommended procedures for optimal safety and device efficacy Q: Can the heating device remain continuously in animal drinking water containers? A: Based on operational safety protocols, sustained immersion is prohibited. Specific restrictions and risks include: Maximum operating duration – Device activation must not exceed 1 hour per session Overheating hazards – Prolonged use increases current load, causing abnormal temperature rises in both sockets and equipment Risk escalation – Sustained high temperatures (>60°C) may trigger insulation degradation or electrical failures Timing control ▸ Implement automatic shutoff mechanisms or manual monitoring Emergency protocols ▸ Immediately disconnect power if abnormal heating occurs The immersion water heater is suitable for small inflatable swimming pools, bathtubs, buckets, etc., (NOT suitable for heating large swimming pools), is a good choice for camping, tourism, bathing. When heating outdoor inflatable pools, it's essential to verify the product dimensions as they are specifically designed for compact setups and not suitable for large-sized swimming facilities. This limitation aligns with their typical application scenarios in residential or small recreational spaces. When you need to heat a small inflatable swimming pool, it is recommended to use more than 2 heaters, which will be faster, but please be careful NOT to plug both heaters into the same outlet. Do NOT touch while heating water and the plug must be disconnected to use water. The temperature is measured by simply placing the thermometer probe in the water and the display on the outside of the container. Warning: The heater can't be used with people/animals in the water, please wait until the water is heated before using.
