Description
Your Solarflo
TM
system consists of several component parts that
work together to heat your domestic hot water supply either
from the power of the sun, by conventional means (by a boiler
or electric immersion heaters) or combination of both.
This combination is required because the sun’s energy is not
uniformly received throughout the year (some 70% of the UK’s
annual radiation is received over the period April to
September). The amount of sunshine hours will vary and the
proportion of direct radiation (from a clear sunny day) and
diffuse radiation (from partly cloudy or overcast skies) will also
vary. However, on average up to 60% of a dwellings annual hot
water requirement can be provided by a solar water heating
system. The balance is provided by the auxiliary heating source.
