compact non pressure solar water heater with 8L ellipsoidal assistant tank

1. We use special water pipe. It is not easy to move, as firm as welding.

2. We use the special red anti-dust ring. It will be easy to change the silicon ring when there is something wrong.

So our system is as firm as welding, but no damage to stainless steel. Our system has longer life time and easy to repair.

Advantages of side feeder 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 unpressure 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 weldings, so there is no leaking. It will also protect inner tank from the hard water corrosion.

Advantage of new silicon ring:

With the common silicon ring,it is easy to fall down when installation, but with our new ones, this problem can be solved.

Working principle:

As water in the collector is heated, it becomes lighter and naturally rises into the tank above. Meanwhile, cooler water in the tank flows downwards into the collector, thus causes circulation throughout the system.
