2 . Features And Advantages
Advantages of side feeder/assistant tank:
1. Without feeder tank, you should feed cold water manually. It is very inconvenient.
2. With the big container on the roof, the main tank is full of water. When the water gets hot, if the hot air can't get
out quickly, there is much pressure in the tank. The pressure will damage the non-pressure tank soon. Secondly, because the tank is full of water, the above welding is dipped in the hot water all the
time. It will make the welding place leak soon.
3. Using side feeder tank, there is a little space on the top of tank, so it will decrease the pressure in the tank.
Because there is no water on the top, the welding will not be dipped in the tank. It makes the tank have longer lifetime
Advantages of no welding:
Welding is a damage to stainless steel. We wrap the cover on the main inner tank,
there is no welding, so there is no leaking.
1.With the common silicon ring,it's easy to fall down when installation, but with our new ones, this problem can be solved.
2. We use special water pipe. It is not easy to move, as firm as welding.
3. We use the special red anti-dust ring. It will be easy to change the silicon ring when there is something wrong.
