Why is there such a big price difference between gas steam generators?

 
Steam generator manufacturers in the sales process, often encountered customers say that others are the same gas steam generator, why the price is less than half of your company puts too much emphasis on profit. In fact, North Africa, now the epidemic when no manufacturer dares to seek high profits, the economic environment of the entire market is not good. So it's not that our manufacturers are expensive, but some manufacturers are cheap.
Why is the equipment of others cheaper? The main reason is that there are mainly so many points, the first is the difference in technical process, many manufacturers of machines or fire row machine, and we are using the full premixed condensation recovery, this above the difference is very big. The price of the fire row is cheaper, but in addition to the price is cheap, nothing else. And if you take into account the gas loss, fire row is not cheap at all, many fire row gas utilization rate of less than 60%, while the full pre-mixed gas utilization rate is much higher than 98%, the annual gas fee is a very high cost.
The second is the difference in materials, many manufacturers use finned tubes also use iron, iron is definitely cheaper.
The third is that many manufacturers produce equipment does not meet the pot regulation, this is very scary. The price is cheaper, but the water volume is much larger than 30L, this time the user's life and property safety is ignored.
