I know there are quite a few threads out there explaining how to tell a Primatic system, but as a total novice, they make no sense to me at all. I've had a few heating engineers look at my system, and one has told me it is primatic, the others have said it's a botched system that is using the same tank twice when it shouldn't. Is there any way that I (as someone who knows very little about CH systems) can tell who is right? Any advice massively appreciated.
Hi Perhaps a photo of the pipe connection to the hot water cylinder may help? Often, the flow connection, is directly connected to the cylinder, without any tee off for the vent pipe. Also, it must be gravity hot water, or to won't work... Regards Peter
