> It’s a shame you have no evidence about the insulated ceiling. I have set the (3rd party) internal thermostat to 30°C, so that it continually calls for heat. All the balancing is done with the weather compensation. The weather compensation “curve” calls for water at 21°C if the outside temperature is 21°C or more, effectively switching the system off. Until then the system modulates down as far as it is capable, effectively reducing compression. Between times the system switches off. As you me…
