VILLA FISSION HEATER

SYSTEM THEORY CHART               

 A. Flat-plate collector     B. Intellective controller

 C. Water tank with heat exchanger

 D. Gas boiler for backup     E. The facility as radiator or shower  

A. REQUIRE

     GOOD SUNSHINE.

    GAS HEATER ACT AS THE BACKUP. SUPPLY HOT WATER ALL DAY AND HEAT ROOM BY FLOOR HEATER IN WINTER.

B. SYSTEM INTRODUCE

1. Heater: divided body drain-back solar water heater.  

2. Collector: adopt the all copper flat-plate collector or evacuated u-tube collector. The size of length or width or the dimension can suit different  building roof or wall. The evacuated u-tube collector can supply higher temperature water than flat plate in winter.

3. Hot water tank: choose all stainless steel insulated tank without pressure. 

4. Working thoery:  

Ø   The frozen fluid circles in the pipeline drived by pump according to the different temperature  between the collector and tank and heated by colletor.  

Ø  If no enough sunshine, strat-up the electric heater in tank to heat the frozen fluid till certain temperature.  

Ø  The gas boiler can also been used for backup heater instead for the electric heater. the frozen fluid from the solar tank goes through the gas boiler. If no enough sunshine, the frozen fluid will be heated by gas till specified temperature.  

Ø  Supply heat water for household anytime which pumped by pressure.  

Ø  When pump stops, water drain-back from collector and keep the collector safe.

5. Control way:

Ø  Controller is checking the different temperature between tank and collector. The pump will been started if difference up to specified value. So the heated water is driven into tank.  

Ø  If no enough sunshine, the controller will start the electric heater or open the gas valve driving water through gas boiler till heated up to specified temperature.

C. SYSTEM ADVANTAGE

1. The system is designed for the users whose house do not fit the integral solar heater. It can supply enough heat water for household and safe, convenient, protecting environment and economy.  

2. The design and installation for integration of solar collector with building, do not affect the district program and decorate the house appearace.  

3. Separate the collector from solar tank and put tank in house.

 ² safe  

  ² good appearance   

  ² insulation    

  ² easyly recruited with conventional energy  

4.  Use solar energy first and convention energy for backup. Guarantee users' comfort, at same time save maximum energy cost.

5. Using the all copper flat-plate collector can realize same working life of building and collector.

6. When no people in room in winter, you can shut gas and keep the pipeline avoiding frozen with solar energy.
