Diagnosed heating system failure in white boiler with no flow to house. Identified multiple issues including a stuck floor control valve, faulty pressure gauge, and possibly malfunctioning ball valve near circulator pump. Replaced pressure/temperature gauge, freed up control valve to restore water flow, and installed relief valve. System was properly pressurized and bled out; however, circulation issues persisted despite pump appearing operational. Recommended expansion tank replacement and auto fill system upgrade from filter trial to conventional configuration. Scheduled follow-up service with boiler specialist for further diagnosis.
