The vacuum tube solar collectors are special solar collector systems that efficiently utilize solar energy for heat production. These collectors usually consist of multiple vacuum tubes surrounded by a thermally insulating vacuum to maximize heat retention and efficiency.
The efficiency of vacuum tube solar collectors is usually higher than that of traditional flat collectors, as the vacuum insulation minimizes heat loss.
They work excellently in cold weather conditions between, as the vacuum insulation prevents heat loss and freezing. and used to support heating systems, especially in places where heat demand is high and the number of hours of sunshine varies.
We offer vacuum tube solar collectors with a 6-year warranty. All our collectors have a CE certificate!

Vacuum tube solar collectors - Peak energy efficiency
Vacuum tube solar collectors offer an innovative and efficient solution for the utilization of solar energy. Compared to traditional flat collectors, they boast many advantages, ensuring outstanding efficiency, durability and reliability.
Principle of operation:
Vacuum tube collectors consist of glass tubes in which a vacuum is created. The absorber surface placed inside the tubes absorbs the energy of solar radiation and converts it into heat. The vacuum provides excellent thermal insulation, minimizing heat loss, so the collector operates efficiently even on colder days.
Types of vacuum tube solar collectors:
- Heat-pipe: In collectors with heat-pipe technology, there is a heat-conducting pipe in the vacuum pipe. The liquid in the tube evaporates under the influence of heat, then releases the heat in the condenser and turns back into a liquid. This heat transfer process is extremely efficient and minimizes heat loss.
- Big-pipe:Big-pipe collectors have thicker vacuum tubes and a larger absorber surface, so they absorb more efficiently away from sunlight. They are ideal for use in colder climates.
- U-pipe: U-pipe collectors have U-shaped vacuum pipes that increase the efficiency of the collector. The liquid in the pipes flows by gravity, so it does not require a pump.
- Tank solar collector: Tank solar collectors have a tank with an integrated heat exchanger in which the heated water is stored. This type is ideal in places where solar energy fluctuates seasonally.
Advantages:
- Outstanding efficiency:Vacuum tube collectors can achieve an efficiency of up to 70%, which far exceeds planar collectors performance.
- Reliability and durability:Vacuum pipes are extremely durable and can withstand harsh weather conditions. The lifespan of the collectors can be up to 30 years, with minimal maintenance.
- Freeze resistance:Vacuum tube collectors can be filled with antifreeze liquid, so they can operate without problems even in winter.
- Environmentally friendly:Solar collectors do not emit harmful substances, thus contributing to environmental protection.
Areas of application:
Vacuum tube solar collectors can be widely used:
- Domestic hot water production:The collectors heat domestic hot water using solar energy, thus significantly reducing water heating costs .
- Heating support: Collectors connected to the heating system provide additional heating, further reducing energy consumption.
- Pool heating:Solar collectors can also heat the pool water, extending the bathing season.
Vacuum tube solar collectors are an ideal choice for anyone who:
- They are looking for an efficient and reliable solution for utilizing solar energy.
- I want to reduce water heating and heating costs.
- They are environmentally conscious and energy efficient.
