Why is it good to heat a bottle of water on the heater? It won’t heat your room, but it can heat it anyway.
How to warm up and keep warm at home?
People have all kinds of ideas and, in addition to heavy curtains in the entrance, they use various other proven ways and gadgets to keep warm cheaper or longer.
There’s also an idea on the internet that should keep you nice and warm in the heat a little longer. It consists in placing a plastic bottle with water near the radiator. While the radiator is heating up, the water bottle also heats up in addition to the surrounding area. At the moment when the heater stops heating the room, the bottle, but above all the water in it, is still warm and this heat is slowly released into its surroundings as the water bottle starts to cool down. Energy, in this case heat, is transferred from a warmer body to a cooler body, which is air.
Unfortunately, it is not as ideal as it might seem at first glance. Although the water and the bottle transfer heat to the room, this is a fairly negligible thermal change and therefore, unfortunately, we cannot speak of any warming of the room by the inertia of the cooling bottle.
In addition, there is definitely no way to save energy. The radiator heated the bottle, the bottle now heats its immediate surroundings. If the radiator hadn’t been rubbing the bottle, it would have warmed the room a bit more. For the trick to work, you need to radically shrink and pretty much strip away the heated space.
Which plastic water bottle tricks work better?
As for the plastic bottle on the radiator, it is an interesting idea, but it would have to be applied a little differently. As? Well, like a hot water bottle. After the radiator is turned off, you can place a bottle or even just a thermos bottle filled with water under the blanket near your feet so that it warms you comfortably while the surroundings slowly cool down.
How else can a bottle or water help with heating? You may still remember that radiators used to have ceramic evaporators filled with water. They increased air humidity especially in very dry block of flats. However, the humidity in the air adds to the feeling of warmth. It’s not about being drenched in sweat due to the hot and humid environment.
But it is a fact that higher air humidity contributes to the feeling of heat. The humidity partially prevents the effective evaporation of sweat, so a person begins to perceive his own temperature more intensely, because he cannot sweat enough to cool down.
