LaZer2 Solar Collectors
The panels incorporate vacuum tubes that have a curved collecting surface. By fitting the panels with the tubes lying horizontally, a constant aperture area is presented to the sun. This automatically compensates for both differing roof pitches and variations in the sun’s angle, making the panels more effective than those systems with either vertically mounted tubes or those with flat collecting surfaces.
Our 93% efficient vacuum tubes work independently of the ambient air temperature and are therefore ideal for cooler climates such as Britain’s.
Solar energy penetrates the glass and is absorbed by the specially selected coating on the collecting surface. Unlike Heat-pipe systems, the water passing through our advanced internal manifold is heated directly so that there is no energy lost.
Plumbing & Control System
The system is designed to be self-regulating, with built in safety controls to give you full peace of mind for minimum effort.
Digital sensors compare the temperature of the water in the panel with that in your hot water cylinder. When the panel is 3°C warmer than the cylinder, the solar pump is automatically switched on and the water circulates through the sealed system. If the temperature difference is below 3°C the pump is turned off to stop the water in your cylinder being cooled.
Solar-cylinder or Heat Exchanger
The option we recommend depends on your hot water consumption, the condition of your current cylinder, and available space.
Our specially designed Solar-cylinders contain a primary Solar-coil (with twice the surface area of a regular one to allow more efficient heat transfer), and a secondary coil for your original heat source. They also have double the insulation of a conventional cylinder so that heat-loss is minimised.
The modern, highly efficient heat exchangers we use fit neatly onto the side of your cylinder. This option is recommended if a replacement cylinder is not required
