East Leake, with black collectors
arranged horizontally in
a vertical array.
He needs the fronts taking off anyway as there are leaks somewhere. Although the fronts hinge up, it would be relatively easy to take them off altogether to get access to the radiators.
They should have been higher as one can see in the photo which reveals a shading risk (photo was taken in February) but he wanted it done without scaffolding and without access to the roof space above.
I've advised him to wait a week or two to see if my sunboxes improve in performance. As he has not taken a data reading since May, there isn't exactly a hurry as there is no way of knowing how the present ones perform. But there is a leak - a dropping off of pressure in the glycol circuit, so there is some work to be done.
