Choosing type of the collector working from solar energy it is necessary to consider the field of its application, climate of the area where it will be used also a lot more different nuances. It is possible to make it independently or to address experts.
To consider everything
Choosing solar collector, it is important to calculate correctly its power and to define for what purpose and where it will be used. It is necessary to know also in what region it will be operated. So, for areas with moderate and severe weather conditions, collectors on vacuum tubes best of all will approach.
The cost of solar collector or the hot water supply in assembly depends on type and complete set of the collector and system gvs. Choosing this device, it is important to consider all nuances.
Country affairs
Choosing solar collector for giving, it is the best of all to stop the choice the device without pressure - the bulk water heater, with automatic set of water. He uses solar energy to warm up water up to the necessary temperature. Choosing such water heater on solar collector, it is necessary to consider the volume of hot water which is spent within day by all family members. It will influence the choice of spare parts. It is better to choose the device with tank store volume corresponding to consumption volume. Capacity of such tank of this collector working from solar energy depends on quantity of tubes - the thermal power of all pipes of the collector, and the optimum combination tank power volume for accumulation of hot water is provided with producers. System without pressure - the simplest among the systems of solar collectors. It does not need mounting of the pump as there is no need to advance water current. The collector is connected directly to the water system which is source of cold water, and hot water will get to the device spontaneously. This full-fledged solar collector on vacuum tubes which transfers warmly to water directly. Its performance is higher, than at other solar collectors as transfer of heat goes without intermediaries. But for the same reason the period of its operation is limited. It is connected stem that it is possible to operate it only at air temperature higher than 0 degree centigrades. Accumulative - the bulk solar water heater working from solar energy is capable to provide 100% of daily need for hot water on the country site and in the country house. The solar collector of this type will provide owners with heated water all summer season. This ideal solution of hot-water supply on the fazenda.
The solar collector can be used for heating of water for country shower, heating of water in bath or heating of the water used for watering of plants.
Choosing the boiler for the country house, it is the best of all to be guided both by the volume of the consumed liquid, and by features of power supply of the room.
The boiler - floor to warm waters of large volume.
Before making choice, it is possible to read responses at forums of the corresponding websites.
To put pressure
Besides systems without pressure, there are collectors working under pressure. Vacuum tubes in it have heat-conducting rod, and internal tank - hermetic. The system under pressure can be used not only during seasonal works, and all year. For this reason it is the most suitable for the house.
