Removing trapped and dissolved air from a sealed heating system is essential for maintaining efficiency, ensuring accurate heat meter readings, and prolonging the system’s lifespan by minimizing corrosion. Ultrasonic heat meters e.g Kamstrup, Axioma, Sharky etc are unable to measure the flow rate i…

[image] Removing air from the system Heatpump I have just installed one of these: " DiSmart 28mm Swiveling Deaerator" It works utterly brilliantly. It removed all the air from the system over a period of a few days.

That’s great to hear. Fitting a Deaerator is covered in the ’ During Design / Installation’ section of the guide.

Personally I specify (and use on my own system) a fill and flush valve to eliminate air from sealed systems and is the only effective way of getting rid of air on commissioning imho. If you have a buffer cylinder or hydraulic separation you would need one on the primary and one on the secondary side…

This is also a very good document. IMI have trained many installers who have gone on to now be known as ‘Heat Geeks’ in this subject - https://mwphs.co.uk/wp-content/uploads/2024/08/mwphs-training-document-imi-air-problems-causes-technology.pdf

Thanks for posting this Richard - a great explanation of all the issues and specifically on page 16 why air vents where they are traditionally placed can miss a lot of what’s going through the system. The air vents fitted by our installer are both just above a bend… We have corrugated coils in the…

Great to see my air issues being flagged. It didn’t take you long to add that feature :smiley:

[image] glyn.hudson: We’re also working on a feature to flag any air issues reported by the heat meter in Emoncms to enable it to be resolved by the installer early on when the system is first installed. [image] SianiAnni: Great to see my air issues being flagged. It didn’t take you long …

Looking at my heatpumpmonitor.org stats, the heatmeter error is only showing on DHW cycles. I’ve compared MyVaillant electricity and heat stats for August with heatpumpmonitor.org : OEM Elec MyVaillant Elec OEM Heat MyVaillant Heat Heating 15.5 22.5 91.0 90.2 DHW 20.3 20.6 ??? 64.6 It…

Now that the heating has been on more, I’ve started bleeding radiators a couple of times a week, and getting air out of one of the top floor radiator each time. Displaying the extent of the error flagged by the Axioma heat meter is a great addition but can someone explain why, in the screenshots be…

I think this is just how Emoncms reducing the number of data points displayed when you zoom out, the correct figure is the figure when zoomed in.
