This gives a neater look – similar to Velux windows
– and saves money on other roofing materials
Pump and controller
The speed of the pump is managed by the
controller. It reacts to the temperature of the
fluid in the solar collector and the water in the
cylinder to automatically determine the rate at
which the fluid is pumped around the system. Evacuator tubes consist of rows of parallel tubes, each
containing a glass thermal absorber. During production,
air is evacuated from the tubes allowing it to reach higher
temperature at all light levels.
• Evacuated-tube collectors have a higher efficiency than
flat-plate collectors, so they may be a good option if you
have a small amount of space
• They can also be mounted in almost any orientation,
from a flat roof to a wall. Even if you already have PV
panels covering your roof, you may still be able to fix a
solar thermal collector to a south-facing wall
