Threesinha group has been a reputed brand name in the industry more than 50 years and the Threesinha solar is its great provide.

Unlike fossil fuels, solar energy is available to a practically unlimited extent, it’s carbon neutral and free of charge. Modern heating systems can be combined with evacuated vacuum tubes, making solar heating systems available for hot water heating.

The use of solar radiation as heat energy is known as solar thermal heating. This is not to be confused with photovoltaics, which is the production of electricity using sunlight. The great opportunities of the use of solar energy have long been recognised: Our tried and tested technology has proven itself over many years.

The benefits of solar heating

       ⊕ Endless amounts of energy, free of charge

       ⊕ No CO2 emissions during operation

       ⊕ Cost savings: up to 60% less energy to heat water, up to 35% less energy for space heating

       ⊕ Reduced consumption of fossil fuels

       ⊕ Solar thermal systems can be integrated into existing systems

       ⊕ Modern systems work efficiently even in winter

Evacuated vaccum tube collectors – Highest solar yields from the tube

The functional principle of the evacuated tube collector is the same as for flat-plate collectors. They as well absorb the solar radiation via absorbers and then transfer it in form of thermal energy to a fluid.

However, in contrast to flat-plate collectors, the evacuated vaccum tube collector utilises the excellent insulation capacity of a vacuum. That's why they are called evacuated vaccum or vacuum tube collectors. Heat losses are almost completely avoided thanks to the vacuum in the glass tube. In addition, a mirror is mounted below the individual tubes to focus the sunlight towards the absorber pipe. All in all, the evacuated vaccum tube collectors are significantly more efficient than flat-plate collectors.

The advantages of evacuated vaccum tube collectors

       ⊕ Greater energy efficiency, good yields even with less sunlight and diffuse light

       ⊕ Require less roof area for the same output

       ⊕ Can also be used on non-south oriented roof surfaces

       ⊕ Produces higher temperatures and can be coupled with high-temperature heating systems
