I stopped using Nest very quickly and I don’t use Nest anymore so I can’t advise on that sorry.

Nest has very limited opentherm capabilities sadly. I used it in my previous house; ideal logic combi; but it suffered from short...

Thank you for sharing that data, it’s an interesting perspective (two countries) and a good point of reference in terms of what absolute...

I believe this is essentially the same boiler. First figure is Italy, second figure is UK

I did once try to get my head around it. If I remember correctly, it's a rather tortuous sleight of hand. It goes something like this...

80, 90, or 100% efficient - does it really matter? Ultimately, all of that energy will escape through the walls anyway ;-)

I cannot see how you could possibly hit 100% efficiency, there is always some waste heat from the flue of a gas boiler. The exhaust...

I mean an actual flow meter to measure the volumetric flow rate, something like this. That particular one requires a 24vdc supply and...

Thank you! That's really interesting; this would be great to compare the heat output value from the precise flow rate perspective. I...

Thanks! What do you mean by flow meter can I ask? If you are referring to flow water temperature only, then it is also provided in real...

Yes, it’s not a lab tested calculation. I guess I could temporarily set opentherm to monitor mode only and compare the relative...

Opentherm tells the real time modulation of your boiler. Based on that information and the manufacturers data sheet, we can calculate...

The basis for the calculation is how much gas has been consumed which is read automatically from my gas smart meter in kWh; the heat...

I would say it’s a decent indicator given what we can calculate but with awareness that there are many more real life factors to...

The gas reading is done about every 2 hours, so if you see anything above 108% that means, for the selected period on the graph, the gas...
