The electric hot water bottle, small, lightweight, cheap, and with good thermal insulation, is highly popular in winter. Safety concerns are paramount when it comes to electric hot water bottles, particularly for rechargeable hand warmers, which are recommended not to be purchased cheaply. Questions about the safety of electric hot water bottles, how to choose one, and safety precautions during usage will be addressed in this article.
What is an electric hot water bottle?
The electric hot water bottle, also known as an electric heating treasure, boasts a novel appearance, large heat storage, long heat preservation time, and convenient use. It is an ideal product for keeping hands and feet warm in winter. There are two types based on the heating principle: electrode type and electric heating element type, including electrode, electric heating wire, and electric heating tube types.
Is the electric hot water bottle a high-power appliance?
Charging hot water bottles are not high-powered, generally ranging from 400W to 1000W. They heat up quickly due to containing heating fluid instead of water. However, in university dormitories, they are often prohibited due to collective circuit safety concerns.
What is the liquid in the electric hot water bag?
There are two types of liquids: supersaturated solution sodium acetate and normal water. The former is non-toxic but can be irritating to the skin and eyes. The latter automatically powers off when heated to 65 degrees Celsius.
Which type of electric hot water bottle is safe?
Three main types are available: electrode, electric heating wire, and electric heating tube. Safer options are electric heating wire and electric heating tube hot water bottles, as electrode types pose risks of rust and potential explosions.
Heating principle of rechargeable heating paste
Soft liquid hand warmers come in two types: electrode and electric heating element. The electrode type uses dual temperature control insurance and is not recommended due to high risk. The electric heating element type uses a resistance wire and a supersaturated solution, providing a safer heating experience.
Electric hot water bottle purchase
Consider the material, bond, logo, and make comparisons when purchasing. Electric heating wire or electric heating tube types are recommended for safety.
How long can a rechargeable hot water bottle last?
The service life is generally 2 to 3 years, and replacement is recommended after two years for safety. The usage time when fully charged is around 6 hours.
Charging the hot water bottle
Follow specific instructions for charging, including using a stable surface, ensuring dryness, and paying attention to the charging time. The bag body may swell slightly during the process.
How to vent the charging hot water bottle
Exhaust methods include shaking it, using a designated vent, or placing a heavy object on it. Avoid pressing too hard to prevent damage.
How to fill the electric hot water bottle with water
Select an empty bottle with matching thread, use a funnel to inject purified water, and ensure the surface is dry before use.
Precautions for using the rechargeable hand warmer
Avoid contact with sharp objects, heavy pressure, and keep the socket dry. Do not use strong solutions for cleaning.
Can a Rechargeable Hot Water Bottle Explode?
Under normal conditions, a rechargeable hot water bottle does not explode. However, if it expands excessively during charging and does not automatically power off, indicating a faulty safety feature, it is recommended not to continue use.
What should I do if the rechargeable hot water bottle is not hot?
Ensure proper water filling, and if the problem persists, it may need replacement due to internal issues.
Can the rechargeable hot water bottle be taken on the high-speed rail?
It is allowed but should not be charged during the journey to prevent burns and potential explosions in crowded conditions.
What’s the matter with the hot water bag charging?
A buzzing sound during charging is normal for liquid electric heaters, but for electrode types, cutting off power is recommended to avoid safety risks.
