The efficiency of a water heater is in heating the declared volume of water to the required temperature required by the user. If the selected water pressure does not get hot enough, then such a water heater is considered ineffective.
When you spend on consumable electricity, you do not get water at the temperature you need. Evaluation of the efficiency of a water heater is carried out according to the type of heating element installed in it. There are more energy efficient and less efficient types of heating elements. Let's take a closer look:
Stitch-heating element - steel wire on a dielectric basis. A technology that's more than half a century old. The heating element is a metal thread laid in a zigzag pattern. It heats up to a very high temperature, the air passing through it warms up and comes out in a warm form. From the pros - instant access to the working t?, literally 5-10 seconds. This is the end of the pluses.
Of the minuses - safety, low efficiency, coupled with disproportionate power consumption, fragility, discomfort during operation. Safety. Wire that glows red. The fire hazard is quite comparable to playing matches near a gas station. Yes, this metal thread cools down as quickly as it warms up, but having something at home with a working temperature of 300?C is such an idea. Low efficiency is primarily due to the small area of ??the heating element. The air that passes through the convection chamber does not have time to heat up sufficiently, since its contact area with the heating chamber is very small. Energy consumption - it is disproportionately large for heat transfer.
The area of ??the heating element must be large, then there will be a normal heat output. So it will heat up for a long time, ineffectively, while taking away electricity according to its rated power. Discomfort during use is a consequence of the high temperature of the heating element.
Steel heating element in an aluminum jacket.
An aluminum jacket is put on the steel tube, which allows heat to be taken from the steel tube and participates in the process of heat exchange. Not as old technology as stitch, but it is also very many years old. There are no pronounced advantages here, but it cannot be said that this heating element is unambiguously bad either. Morally old? Definitely. It was adequate for its time, but now this technology is simply outdated.
Compared to stitching, the operating temperature is much lower here, so there is no feeling of burning out O2 and foreign odors. The main disadvantage is the noise of work. The heating element consists of two components - a steel tube and an aluminum jacket. The steel tube heats up and transfers heat to the aluminum. Since they have different expansion temperatures, aluminum will expand and contract during heating and cooling, making metallic sounds.
Monolithic heating element.
Monolith is the most advanced and expensive. It is made of a monolithic composition of silumin, which is cast in a single mold. The shape of the heating element is X-shaped, which is why they are often called X-shaped heating elements. Although there is also a V-shaped heating element, this is already used in the same baseboard convectors (where the X-shaped heating element will be redundant). Due to the fact that the structure is monolithic, in contrast to the heating element in an aluminum jacket, it does not cause any clicks and crunches during the heating and cooling process. It has the largest area, so there is the largest heat output and it will warm up the room the fastest. The speed of reaching the operating temperature is only 75 seconds.
Stitch is the worst of all. It has the right to exist only in fan heaters, and even then it is better to buy heaters with a ceramic heating element. The convector with a steel heating element in an aluminum jacket is morally old, but for some reason someone makes them and uses them, although they are better than stitching. The monolith is the most advanced heating element, but the quality of the monolithic element depends on the manufacturer, since they are all different. If you are now looking for a good heater, we recommend buying an inverter convector. These are the most technologically advanced electric heaters at the moment, inside of which, in addition to a monolithic heating element, an inverter control also saves on electricity, optimizing it by an average of 30-35%.
