I have a similar issue with Short Cycling. I addressed this in many ways but the most practical so far is to do away with the Boiler Thermostat and install an Elliwell unit. In short I can control both the upper temp the boiler turns off at and the lower temp it re-fires. It has made a significant improvement to the running of my system, more so that a few degrees increase in Boiler flow temp make a big difference in the house.Pic below. Top unit is the Elliwell turns off at 60c and back on at 45c this also assists keeping the Boiler in Condensing mode with return temps never higher than 47C. Middle Unit Flow and return Temps Bottom Unit is an Hour Meter. Im about to invest in some Salus Auto Balancing Actuators. Happy to answer any questions. Ignore Temp readouts, I had the Bypass open and pump to max too check settings and parameters.
