Watermark Porcelain Enamel Hot Water Storage Tank 80L-500L for Solar and Heat Pump

Changzhou XNE Group is a professional manufacturer of enamel hot water heater, solar collector and solar water heater with approval WaterMark, Solar Keymark,IEC/CB, CE, ISO and TUV, SGS audits in Changzhou, China.



Three types of Water Tank are available: 1) Tank without heat exchanging coil; 2) Tank with copper coil; 3) Tank with enameled steel coil.

 
New Technology - Water storage tanks are adapted to the advanced technology of vitreous enamel inner tank XNE Enamel Blue Inner Liner, which fuses to solid steel at about 900°C. The result is a smooth and tough surface that effectively resist the corrosive attacks of hot water chemicals, thus ensuring a long life span of water tank, especially suitable for the areas of hard water.


 
Best materials 
* Enamel: imported from USA Ferro who is the worldwide biggest enamel manufacturer;
*  Inner tank steel: from Baosteel who is the Chinese biggest steel manufacturer;
*  Steel surface cleaning Grit: imported from French W Abrasives who is the worldwide biggest abrasives manufacturer;
*  Pressure and Temperature Relief Valve: imported from Canadian Watts;
* Thermostat: imported from USA Emerson;
*  Electric Element: from Japanese company Kawai.

Insulation protection - CFC free polyurethane foam insulation is injected and surrounds the inner tank, filling the space between the inner tank and outer tank thus providing an exceptionally good heat retention barrier. This helps to reduce the energy cost by minimizing standby heat loss.
 
Electric Element - Low density Incoloy 800 immersion type element ensures long lasting performance with choice of various heat input (kw) offering different hot water recovery rates.
 
Anode Protection - Each tank is provided with a magnesium anode rod to protect it against corrosion, a process well proven in years of application.
 
Safety Protection - Each tank is provided with a pressure and temperature relief valve (P/T valve). It protects the tank against excessive pressure and temperature by releasing its contents safely to the floor trap via the drain pipe.
 
Compliance - Australian certification WaterMark, International electrical safety certification IEC60335, CB and European certification CE
 
 
Customized - We can make the customized tanks according to customer's requests.
 
Wide Application Water tank can be working standalone as an electric water heater, and it can also be working with solar collector, heat pump, gas, etc. like the following drawing: 
 

Type of tank:
- Pressurized, vertical or horizontal, working pressure up to 0.85 MPa / 8bar.
- Split, separated water tank
- Balcony, Integrated water tank
- Roof stand water tank
- Ground stand water tank

The heat exchanger:
-cooper coil type and enameled steel coil type (also called heat exchanger), one coil or double coils (first choice is for the high latitude places)
-Non-cooper coil type (first choice is for the low latitude places)

The hot water storage tank can work standalone, but their two most common installations is working with the two alternative energy sources Solar Collector and Heat Pump with the back-up devices:
-electric heating,
-gas boiler.
