Heating film is the heating method that many people will choose now, but can you really distinguish between the good and bad of heating film?

A good radiator can not only make you more comfortable, but also save a certain amount of energy consumption. Learn the following four tricks, so that you can easily choose the right radiator, do not worry about being fooled.

Now 80% of the heaters in the market are steel heaters, so we take steel heaters as an example.


Steel plate radiator

1. See how the details are handled.

The same type of product, the same performance, the same appearance, unable to distinguish, you can see the details of its processing. You can see whether the edges and corners of the radiator are treated roundly, whether the radiator feels smooth, and whether there are any uneven places. We often say that details determine success or failure, a product, if the details are not handled properly, other places do not need to see.

2. Look at the heat dissipation fins

The heat dissipation principle of the heater is hot water flowing into the sink, heat conduction fins, heat rising, heating the cold air above the heater, so circulating, heating the room temperature, so the heat dissipation fins is the key. So what do you think of the heat sink fins?

Here are two things to judge.

First point: Look at the height of the radiating fins. In the 600 mm x 900 mm model, A and B represent two heaters respectively. If the height of A's fin is 500 mm and B's fin is 550 mm, spread out, and their spreading area B > A, then B's heat production will be larger than A's. Under the same heating area, B's heating and heating rate will be faster than A's.

Height of Heat Dissipating Fins

Second point: Look at the number of fins. Similarly, in the 600 mm x 900mm model, C and D represent two heating fins, each with a height of 500 mm. The number of C fins is 32, and the number of D fins is 28. Their spreading area is C > D. So C will produce more heat than D. Under the same heating area, the heating capacity and heating rate of C will be faster than that of D.

3. Look at the paint

Nowadays, the latest baking technology is basically used for the appearance of heating panels. The baking technology has heat resistance, moisture resistance, wear resistance and corrosion resistance. As we all know, the water quality is corrosive, so the thicker the paint, the better the corrosion resistance, and the longer the service life.

PS: Generally speaking, the regulations for heating sheet paint are three sprays and three bakes. Spraying paint generally bakes the paint surface, sprays paint and bakes again, sprays paint and bakes again. Continuous spraying and baking can meet the process standard of baking paint.

There is a range of paint thickness: 0.2mm-0.8mm

How to judge the thickness of paint?

Look at the color and luster of the paint. Generally, steel heating panels are white coatings. The more times the paint is baked, the darker the color is.

The picture is to distinguish white paint, for reference only.

4. Look at the thickness of the steel plate (that is, the wall thickness of the heating plate)

The wall thickness of the household heater must ensure that the heater can withstand certain pressure, but also to ensure that the heat dissipation of the heater is optimal. Therefore, the wall thickness of the national standard radiator will have a certain range of different materials. The wall thickness of steel radiator is generally over 1.2 mm. 1.2mm-1.6mm is thin steel heating plate, and over 1.8mm is thick steel heating plate.

The wall thickness of radiator must meet the national standard. The wall thickness of radiator should not be less than 1.3mm. The radiator under this standard not only has insufficient compressive strength, but also has a long service life. If the wall thickness of the heater is higher than the national standard, it will affect the heat dissipation effect. By the way, the compressive standard of the heater requires a higher compressive strength (> 1.0 Mpa) to ensure product quality and safety.

How to judge the thin thickness of the radiator?

Listen to the voice

The clearer the sound is, the thinner the steel plate is; the thicker the sound is, the thicker the steel plate is.

Wall thickness is an important guarantee for the performance of anticorrosive heaters. In heating system, there are pressure of water itself and pressure to promote the normal circulation of the system. This requires anticorrosive heaters to have certain pressure-bearing capacity, which can ensure the safe operation of the heating system. In addition, due to the different water quality in different parts of the country, the oxidation corrosion of heaters is inevitable. If the heating wall thickness is increased, the corrosion of the heater is inevitable. The service life of the radiator can be greatly prolonged by the anticorrosive treatment inside the foot.
