Solar Hot Water Applications
Heat loss from the pipework connecting a solar panel to a hot water cylinder can reduce the effectiveness of a system, greatly reducing the expected payback. Insulation of solar pipework reduces energy loss making the system more efficient throughout the year. This is especially important during Autumn, Winter and Spring months as the energy saved directly offsets the need to revert to conventional boilers.
Solar hot water pipework is, however, more challenging to insulate than conventional domestic hot water systems. Panels are always located outdoors, often long distances from the hot water cylinders and insulation on the connecting pipework is prone to attack by rats, birds & other vermin. Damage of this type exposes the bare pipe, creating thermal bridges which reduce insulating performance and increases energy loss.
In order to prevent energy loss from solar hot water pipework the following attributes should be displayed:
