Sun Stream Vacuum Tube Collectors Sun Stream Flat Plate Collectors
Vacuum Tube Collectors
FirstLight Energy’s unique “Sun Stream Solar Water Heaters” are produced in a state-of-the-art manufacturing centre. Sun Stream vacuum collectors use a triple coated absorber that converts up to 96% of the energy captured. The circular design presents a perpendicular absorber area throughout the day and the reflected solar radiance from behind maximises the free energy available.

Vacuum Tubes
Sun Stream vacuum collectors use a triple coated absorber that converts up to 96% of the energy captured. The circular design presents a perpendicular absorber area throughout the day and reflected solar radiance from behind maximises the free energy available. The advantage of this technology is improved thermal efficiency, lower emittance rate and a working efficiency in high temperatures of up to 250°C
High quality borosilicate glass is used throughout.
Manifold and FrameThe manifold and frame are made of high grade galvanised steel, finished in a textured black powdered coating, designed for long life. The reflector plates are produced from aluminium also on a galvanised steel frame.
The insulation within the manifold is injected high grade polyurethane foam.
The copper tube (male) in and out is 3/4" or 1" BSP. All fittings are stainless steel.
Heat pipe technology is used to ensure ease and speed of installation whilst ensuring high efficiency of the system.
