Solar thermal collectors (Evacuated tubes)

1. Evacuated heat tubes encased within aluminium heat fins contain pure water and additives within a vacuum for more effcient heat transfer. The evacuated glass tube vacuum acts as a super-efficient heat trap, aluminium nitride coated heat fins then absorb the solar energy

2. Strong aluminium casing houses a copper manifold that is non-corrosive; the rockwool insulation provides excellent insulation against freezing and can withstand high temperatures up to 250°C

3. Solar controller regulates circulation of solar water and prevents frost formation

4. Safety relief solar valves ensure system doesn't reach dangerous pressures when water reaches high temperatures

5. Insulated copper connection lines prevent heat losses to and from hot water cylinder

6. Connect to a wetback for extra energy savings in winter (stainless steel hot water cylinders available for this purpose)

7. Insulated hot water cylinder with electric booster ensures a constant supply of hot water, no matter what the weather (available with a heat exchanger for closed loop systems)

8. Circulating pump uses minimum power to move water between solar panel and hot water cylinder
