Low-Pressure Solar Geyser

DESCRIPTION

The evacuated tube collector (ETC) consists of a number of sealed glass tubes which have a thermally conductive copper rod or pipe inside allowing for much high thermal efficiency and working temperature compared to the flat plate solar collectors even during a freezing cold day.

Solar hot water systems that use Evacuated Tube Collectors as their heat source overcome this problem because the solar collector uses individual rounded tubes which are always perpendicular to the sun’s rays for most of the day. This allows a solar hot water system using an evacuated tube collector to operate at a much high efficiency and temperature for a much longer period than a conventional single flat plate collector installed system.

FEATURES

1. The Evacuated tube collector consists of a number of rows of parallel transparent glass tubes connected to a header pipe and which are used in place of the blackened heat absorbing plate we saw in the previous flat plate collector.

2. These glass tubes are cylindrical in shape. Therefore, the angle of the sunlight is always perpendicular to the heat absorbing tubes which enables these collectors to perform well even when sunlight is low such as when it is early in the morning or late in the afternoon, or when shaded by clouds. Evacuated tube collectors are particularly useful in areas with cold, cloudy wintry weathers.

3. Evacuated tube collectors are made up of a single or multiple rows of parallel, transparent glass tubes supported on a frame. Each individual tube varies in diameter from between 1" (25mm) to 3" (75mm) and between 5′ (1500mm) to 8′ (2400mm) in length depending upon the specific country customers locating in.

FAQ

1. Location:

   Building 1, No. 2, Jinniu Road, Jianshan New District, Huangwan Town, Haining City, Jiaxing City, Zhejiang Province

2. MOQ

   USD1,000.

3. Do solar thermal systems produce hot water in the winter? What about when it's cloudy or cold?

4. At times, especially during long periods of cloud cover, some light use of your backup system may be required to meet demands.



5. Can I use a solar space-heating system in place of my existing traditional gas or electric heating system?

6. A solar space-heating system can take care of the bulk of your space-heating needs, significantly reducing your heating bills. However, in some instances, such as on days when it's cloudy or rainy, the solar space-heating system may not be able to provide all the heat you need to keep your home or business warm. That's why we strongly recommend that you get you a solar space-heating system installed in conjunction with your existing heating system.

7. Payment Term

   Ususally 30 deposit before design and 70% balance before container arrive in destination port.

8. Warranty Terms:

   5-year for the whole system/10-year for the vacuum tubes.
