The Westech Evacuated Solar tubes are a reliable off-grid solar generator specifically designed for home and garden applications. We have 21 used and 1 unused which are ideal for replacing broken tubes on your current system or for spare parts. We changed to a combi boiler so these are no longer compatible for our system. I looked a couple of years ago and just for 1 tube they were fairly expensive . I Would rather sell to someone that needs them for a reasonable price than throw them away. They need a clean, however I will do that before collection. There are also 3 copper heat pipes available that I took out of discarded damaged tubes.
