1. Hot water tank 01: Brief introduction Energy storage hot water tank is a collection of multiple energy sources. It can meet other auxiliary heating systems when one heat source can not be heated, so that the water tank can be used all year round. Our LED Emergency Twin Spot Lights are a cost effective replacement for old fashioned halogen emergency twin spot fittings. Due to the low power consumption of the LED lamps, only one battery is required, reducing option during charging. The super bright adjustable heads make this twin spot ideal for commercial and industrial applications. with a self test feature every 90 days to ensure correct operation. The Led Emergency Lights design makes it quick and simple to install.

02: Advantages of Cosman coiled hot water tank:
The European standard super large magnesium rod design (diameter 30mm * length 600mm) can effectively alleviate the corrosion of the tank due to water quality problems. German food grade special SUS304 stainless steel coil, anti-scaling, anti-aging; straight 25mm coil diameter design, reduce water flow resistance, increase water flow, system operation is more stable. The inlet water cooling water pipe adopts a mesh-like shunt structure, the water flow is more reasonable, more comfortable and energy-saving. 
03: Selection points of energy storage hot water tank:
1. Choose the hot water tank capacity according to the number of people and the number of equipment;
2. The use of large magnesium rods can effectively alleviate corrosion;
3. The magnesium rod head and pressure gauge must be made of stainless materials;
4. The interface must use real 304 stainless steel.
Note: The simple way to check whether it is stainless steel is to use a magnet without any suction. 
2. Buffer water tank 01: Introduction Buffer water tank, also known as energy storage water tank. Mainly to increase the water capacity of the system, delay the start and stop time of the host, reduce the number of start and stop of the host, so as to achieve the purpose of energy saving and protection of the host! The buffer water tank also has the effect of sewage and exhaust pressure! 
02: Advantages of Cosman buffer water tank German food grade special SUS304 stainless steel liner, anti-corrosion, long service life; standardized design, equipped with high-quality exhaust valve, to achieve the best energy storage, exhaust, buffer effect.
Note: The position of the water inlet of the buffer tank should not be too low. 
3. Comparison of hot water tank and buffer water tank 01: Difference between hot water tank and buffer water tank Buffer water tank: closed system, with exhaust valve Hot water tank: open system, with PT safety valve, with magnesium rod, available The size and layout of the connection between the coil and the auxiliary heat source buffer water tank and the hot water tank are also inconsistent (see figure). 
Cosman's new energy storage system includes energy storage hot water tanks and energy-saving buffer water tanks. A new energy storage mode that integrates an energy-saving control system and a multi-function pumping station system. Among them, the collection, transmission, storage, and utilization of energy with the energy storage hot water tank as the core. Cosman energy storage hot water tank is a multi-energy multi-purpose water tank.
