Hello,
just a quick update to say the megaflo is in and working great with the GD80 Rayburn. Thanks to everyone on here for their help. All got installed by heating engineers, but one slight difference with the megaflo wiring instructions is that because it's a pump overrun boiler for the heating side in the Rayburn, it needs a permanent live and you run the pump from the output of the boiler - not a great deal of difference but maybe worth mentioning.
Thanks again
