Ideal vogue maxc32 efficiency level

Mines will cycle more than 'normal' I guess since it`s only used on manual, via Hive thermostat. We switch it on at normally 18-19c depending on the house/outside temps. We don`t have zones or timed settings. It`s left on 24/7 and the Hive is dropped to 12c instead of switching off at night.
I have the boiler heating set to 70c and drop it to 55-60c come Spring/Summer. I`m not sure if that`s the most efficient way for us to use the heating tho`.

It would be nice if they quantified or explained this better because the condensing effect only just kicks in at ~ 55C return temp, you would need to get the boiler return temperature down down to 45C get a reasonable condensing effect of say ~ 8% to give a boiler efficiency of 95% from ~ 87% at 55C.

Temperature the heating is set to 70?

 

[CMPropsvcs]

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.

Old thread I know but thought peeps might like the response I got from their tech team , although not much of one it has to be said.
I asked if the definition was written anywhere , just for my interest because at the time I was just starting using Opentherm with the Google Nest.
My SEL has worked its way up to 93% over the year 22/23 , with flow return temps anywhere from 43/36 to 49/39.
Just for interest by my calcs OT uses around 16% less gas in my house by my calculations.
Anyway this is the , short , response I got .
Hope it's of use
