@editor the easiest way to find out is to look at the data on open energy monitor.

we seem to have a fascination now with low end mod which good control it will shut off down there anyway and there’s nothing better than it being off. 

also be more careful with the units drop off rather than the low end mod, the 8 will probs only give you 6 and the 6 will only give you 5.

with how these things work the low end isn’t always going to be that great but just use a good Heatpump, a Viessmann, Vaillant grant or Nibe. They use degree minutes to keep the compressor off.

we have a weird fascination with wanting crazy long runs times with I think is daft.
