Evacuated Tube Collector

The evacuated tube collector is widely used for domestic water heating. These collectors consist of an absorber surface inside a tempered glass vacuum tube. The vacuum helps to reduce convective heat loss. The performance of this type of solar collector is superior and therefore one of the products that we recommend the most when dealing with special situations such as shade on the roof, difficulties with the north facing position or very high energy consumption. These types of collector are also suitable for freezing conditions.

Evacuated tube collectors reach hotter temperatures than flat plate collectors. This output can help when extra performance is needed. oneSolar uses a controller on all installations, which has several functions. One of them is to control the pump according to the heat in the geyser ensuring that the geyser does not overheat. Other functions allow you to set your desired temperature in your geyser and to ensure that your geyser element does not switch on during peak time, which is a pre-requisite in order to get an Eskom Rebate.

There are many advantages of an evacuated tube collector, including the following excellent features and benefits:

• Superior efficiency all year round
