What affects heat saving?
Everyone gets a thermos in order to take hot coffee or tea with them. The main thing is that your favorite drink retain heat for as long as possible. As a rule, such products retain an average temperature of 6 hours. But there are models that retain heat for up to 12 hours, provided that the thermos does not open regularly. Several criteria influence the duration of thermos thermos storage.
- One of the factors is the volume of the product itself.. For example, if you pour boiling water into a smaller container, then you should not count on the long-term preservation of heat. The larger the volume, the longer the heat will remain.
- It depends on the degree of filling of the container. If a thermos, for example, with a volume of 1 liter, is only half filled, then a hot drink will cool faster than in a thermos, which will be filled to the end.
- As a rule, large thermos-jugs or classic thermoses, which are convenient to take on a hike and to work, retain heat longer than a thermomug. Therefore, it still depends on the type of product and on what you purchase it for.
Important! The heat storage is affected by the material of which the thermos is made, its quality and some other criteria.
Choosing a high-quality thermos, many are of the opinion that a metal accessory will retain heat longer than a plastic product. In fact, this is not always the case. Even if the model is made of stainless steel, but the metal is very thin and of poor quality, such a thermos will not be able to effectively retain heat.
It is best to choose a product with thick metal walls. In addition, there should be a vacuum space between the body and the bulb itself, which allows you to retain heat longer. The best option is a product made of quality metal with a glass bulb. And you can also choose the option with a stainless steel flask. Such a model will also retain heat well and, unlike glass, will last longer.
If you want your accessory to stay warm longer, pay attention to the diameter of the neck. The smaller it is, the longer the heat will remain, even with regular opening. It is also important to pay attention to the type of cover. It can be a screw, cap, or valve. All of them allow high-quality and long-term storage of heat, but the cap-cap is less practical, since it can be lost, and it also wears out quickly.
You can evaluate the quality of the product in just 10 minutes. Pour boiling water into a thermos, if after 10 minutes the case heats up, then you should refuse such a purchase. The case of a quality product must remain cold.
