The bubbling sound is more like boiling water. And how should we understand the extinguishing of the furnace? Have you stopped adding fuel or maybe closed all the doors? Simply opening the radiator valves will not reduce the temperature on the stove from 80-90* in a short time if there is no circulation because there is less water in the system.
The discussion revolves around issues encountered with a central heating stove system, particularly after boiling water exceeded 100 degrees Celsius. Users report melted insulated pipes and cables, a malfunctioning central heating pump, and discrepancies in temperature readings between the oven thermometer and the controller. Concerns are raised about potential damage to the pump due to running dry and overheating, as well as the possibility of warranty claims. Suggestions include checking for air in the system, ensuring proper water levels, and considering the installation's design. Users also discuss the need for pump replacement and the implications of warranty coverage when opening the pump for inspection. Summary generated by the language model.
