Adam could you please explain how you know it’s a floating system…..

What is it in the diagram that’s telling you that…I’m having to fill out a form to get certification to use the system…it’s a real pain but I remember you saying this and it could be very relevant…..Mike

I have on my condensing boiler water outlet pipe inside just below the boiler a diverter that I can divert water into a plastic bucket I cut a piece out of the pipe and replaced over the pipe with a see through pipe that has a red ball in and a knob to turn so when outside pipe freezes up I have the knob turned so water goes down a plastic tube into the bucket. Had it for 4 years and no struggling to defrost outside
