    Sick of current UK suppliers is it worth giving one of the new smaller suppliers a go

It serves two bedrooms (5 doubles apiece), currently with a...

    Testing Results

    I'm by no means an expert at testing hence the reason I'm asking this question :D so was just wondering in general is r1+r2 bigger or smaller than Zs. From the testing I've done I've noticed they seem to be pretty similar but sometimes r1+r2 is bigger than Zs and sometimes smaller! :confused:
