Wall-mounted stoves to buy four major standards

temperature

The independent heating system with the fireplace as the core is different from the central heating in the north--the government guarantees the warmth of the indoors of the residents by ensuring the supply of coal and monitoring the operation of the equipment. When consumers buy a wall-hung boiler, they must see if their temperature can be controlled by themselves. Whether the heating time can be arranged by themselves. Good wall-hung boiler products can intelligently adjust the temperature according to the user's heating demand. The user can choose the most comfortable heating temperature. If it is equipped with a thermostat, it can also regulate the heating temperature of each room and arrange the heating time independently.

humidity

The winter climate is generally dry and cold, which is detrimental to the prevention of people's respiratory system. The choice of household wall-hung boiler heating equipment should look at the heat-discharging mode of the heating system under the condition of temperature guarantee. Generally, the traditional heating method, the temperature is up, the humidity is gone, people will feel dry and uncomfortable. Users who use the wall-hung boiler can choose the appropriate heat dissipation method according to their own humidity requirements. The installation of floor heating or heat sinks will bring different humidity environments to the room. Experts suggest that consumers should buy products with a strong brand influence, and these brands generally provide comprehensive heating system installation recommendations.

Energy saving

It is also important to check the air consumption when purchasing a fireplace. The heating area of ​​the wall-hung boiler is much larger than other heating methods, which is fast, hot, and consumes less air. According to the data of the German professional heating group Weineng, in general, the efficiency of the wall-hung boiler can reach more than 90%, and the new condensing boiler can achieve a higher efficiency of 109%. Compared with electricity or other means of heating, gas heating can save 30%-40% efficiency, energy-saving is unparalleled. At the same time, experts suggest that it is best to install a thermostat, which one to use, which will consume less energy.

Air cleanliness

With the improvement of building quality and energy saving requirements, the airtightness of the room is getting better and better. Therefore, clean and effective ventilation is becoming more and more necessary for healthy home. Indoor air quality directly affects the quality of life. Therefore, the purchase of household wall-hung boilers should avoid problems such as noise, airflow, harmful gas emissions, dust pollution, air occlusion, and drying. In today's wall-hung boiler market, wall-hung boilers such as Granville can generally heat up evenly. The way of radiating heat makes the temperature constant, healthy and comfortable, warm and pleasant, without causing air dust to fly everywhere. .

Conical Lens

Plano-Convex Axicon, Conical lens, Bessel beam, ring shape, Bessel beam Plano-Convex, Axicons,Conical, lens.

Axicon (conical lens) is a conical prism used to create non diffractive Bessel beams

Axicon lenses are conical lenses which, when followed by a conventional lens, can focus laser light to a ring shape. Using an axicon together with a Spherical Lens will produce an annular focus for hole drilling applications. We offer Plano-Convex , Plano-Concave, Double Convex Axicons.

such as fluorescence microscopy, spectroscopy, clinical chemistry, or imaging.
These filters are typically used in the life science, industrial, or R&D industries.
