How about Huangming Solar Energy?

What size of solar water heater is suitable? (Don’t buy expensive ones, buy the most suitable ones)

Generally speaking, adults use about 40-50 liters of water for each shower and 100 liters of water for bathing. For example, if a family of four uses a shower in winter, there is no special need, and a model with a capacity of about 200L is enough.

However, the water consumption of different hot water lifestyles is very different. For the same family of four, the hot water demand is different. Some bathrooms have many bathrooms and the bathing methods are also different, such as tub bath, For home SPA, laundry, vegetables, and car washing with warm water in winter, you need to choose a large-capacity hot water machine.

The colder the winter, the more hot water is needed

There are three major links to ensure it is useful in winter, heat collection, insulation and heat transfer, all of which are indispensable.

For example, in the heat collection part, the key is the vacuum tube. How to choose? To put it simply, if you look inside the tube, the one that is opaque is better, the one that is heavy is better, and the one that makes a crisp sound when you knock the tube is better.

As far as vacuum tubes are concerned, Huangming has developed different series of vacuum tubes according to the climate of various regions, such as the northeastern alpine regions, northern regions, rainy areas, etc., to meet users' needs for hot water all year round.

Which series should I use at home?

Why should I choose a brand and Huangming?

Word of mouth! Huangming's products are notoriously expensive in the industry. They have been expensive for nearly 20 years and will continue to be expensive, which shows that consumers recognize it. In fact, consumers are the savviest. They may be defrauded for a short time at most, but it is absolutely impossible for them to be defrauded for 20 years.

For example: We have never regarded the antifreeze belt as an insignificant accessory, but as a perfect match for hot water in winter. Because until we improve it, we lose a lot of trust.

After the melamine incident that year, Huangming's headquarters held an emergency meeting at all levels to investigate whether "melamine" existed in Huangming for 7 days and 7 nights. Finally, it was found that in 2008, there were more than 200 fires caused by Huangming products due to corrosion and leakage of antifreeze belts.

The root cause is that the joints and ends of the antifreeze tape were improperly handled during installation. Even though we have carefully wrapped and wrapped them extremely tightly with multiple layers of insulating tape and waterproof tape, the long-term outdoor use At work, it is not difficult to open the glue and let water in.

The only solution is to strictly seal both ends of the antifreeze belt in accordance with military industry standards before leaving the factory. But when this change is integrated into the entire hot water system and eliminates hidden dangers, you will realize how long overdue this change is.

The trouble here is not that we have to open a new production workshop and increase costs, but that the length of the antifreeze tape has been fixed, but the length of the pipes in each family is different, so this technology is provided to dealers It will cause a lot of trouble to the installation engineer.

In the past five years, even if users don’t understand, we still insist on pushing it to thousands of households. We prefer to say "Sorry for wasting your time" at this time, instead of hastily saying meaningless "I'm sorry" after the accident. This technology has not been patented, but in the past five years, not one of the more than 7,000 solar energy companies across the country has followed suit.
