The majority of people in Britain are under the misconception
that solar power only works when the sun is shining. You have
only to look at the amount of systems in countries like Sweden,
Denmark, Finland and Germany to see that Britain is far
behind with this way of thinking. The evacuated tubes don't just rely
on sunshine, they harness solar diffused radiation, so that even on
the coldest days when there may be no direct sunlight they will
still produce hot
water.
Using the latest Resol Controller with 3 sensors you will be
able to see just how much hot water you have at anytime. The
LCD readout shows a diagram of your system indicating the
temperature of the tubes output on the roof along with the
water temperature at the top and bottom of your domestic hot
water storage tank.
