Discuss Ideal vogue maxc32 efficiency level in the Central Heating Forum area at PlumbersForums.net
I had an Ideal Logic + fitted in early September and the flow temperature was set at 70*C. After Christmas I experimented with the temperature and set it at 60*C that gives me a return of 50*C. I’ve been recording the Super Efficiency figure for a week and it’s increasing almost daily from 28% and is now 35%. It now looks like percentage figure is a ratio of time the boiler is operating in Super Efficiency and total time. I’m guessing the 28% I started with was the best efficiency at start up and dropped off as the circulating water return reached a point when it stopped condensing.Temperature the heating is set to 70?
As a percentage of what I wonder, if its the percentage firing time then 37% would seem that this boiler is cycling on/off quite a lot? but might be the % modulation?.Thank you for your enquiry. The efficiency level shown is not the overall efficiency of the boiler, it is the amount of time the boiler has run from new (as a percentage) in it’s super efficiency level. The figure will rise or fall. We recommend the heating temperature to be set around 70 degrees C on the boiler for increased efficiency.
Now sitting on 37%
It's the fraction of 'firing time' that the boiler has spent operating in condensing ('super efficiency') mode, i.e. with the return temperature below some unspecified threshold that is presumably around 50°C. It doesn't tell you anything about 'cycling on/off' or '% modulation'.As a percentage of what I wonder, if its the percentage firing time then 37% would seem that this boiler is cycling on/off quite a lot? but might be the % modulation?.
Temperature the heating is set to 70?
Temp set to 65c
Ideal have said “depends on settings” but will be getting back in touch
It’s just the lcd screen on the boiler itself. Temp is 65c for central heating.
