Most economic heating. Long/ short intervals?

Hi All,

I switched from thermostat build in into my central heating boiler to generic thermostat integration recently and I generally like it how it works, how I can control it etc

However after month usage I noticed my gas consumption is higher than was before.

What I also noticed currently my boiler now fires much less frequent than before but for longer time.

I know I can get similar behaviour changing cold /hot tolerance, but my question is:
based on your experience / knowledge - what is more economical?

  1. keep heating / break intervals short
  2. wider heating / break

Obviously I know that from comfort perspective #1 is always winner - but I’m now considering only economical perspective (Im not often in that flat, I want to keep it cheap, but not too cold ).
If #1 is your advise - do you have any tips re cold/hot tolerance / other values / settings ?

Below are my current settings (I want to keep 18C in biggest room )

    target_temp: 18
    cold_tolerance: 0.3
    hot_tolerance: 0.1

After change
