The heat pipe system is the latest version of the vacuum tubes system and presents several advantages compared to the standard vacuum tubes system. While sharing the enhanced performance of the vacuum tubes, the heat pipe is able to prevent many of the inconveniences related to the previous vacuum tube system. What is a Standard Vacuum Tube?

Evacuated tubes which absorb the solar energy converting it into heat have already been used for years.There are several types of evacuated tubes in use in the solar industry. The most common is the “twin-glasstube”, often chosen for its reliability, performance and low manufacturing cost.

Heat pipe pressurized compact system come in capacities of 200 Lt and 300Lt
