Hi All,
I had an Intergas boiler fitted probably three years ago now along with a Nest v3 for the OpenTherm functionality.
I have long suspected that its not been modulating correctly / short cycling but I could be wrong.
I have been monitoring the flow and return temps from the boiler for a few days. The boiler seems to come on every 10 minutes (possible anti-cycling setting) for anywhere from 2-5 minutes. This can be longer when the boiler first fires up in the morning but that's the average - see the graph.
Does this look normal? Should it be coming on this frequently? To me it would make sense, if the nest is calling for a 40 degree flow, to modulate down to the lowest output and burn for a longer period of time?
The graph attached is for a 20 degree room temperature and the room was at 20 degrees so its just maintaining this temperature really.
Could adjusting the max CH output parameter help with this? It seems the flow temp is rising too quickly?
Bit of a nit picky post! I just don't really understand what the Nest/Boiler is trying to do!
Cheers
Andy
