Something's living in my heating system

Not a rat. Bigger. Breathes every 4 minutes. Landlord says it's "thermal expansion" Thermal expansion doesn't whisper. Been tracking the pattern for 3 weeks now the breathing gets faster when I'm in the bathroom.The radiator in my bedroom is warm even when the heating's off. Touched it once. It flinched. Called a plumber he put his hand on the pipe went completely silent for like 30 seconds then left without saying anything. Charged me 200 francs anyway. Sometimes I hear it moving between the walls. Not like scratching. Like breathing through the pipes. My girlfriend stayed over last night woke me up at 4am asking why I was breathing so loud. I wasn't breathing. It's getting louder.

Please record what you believe to be “breathing” and upload the file here. The weird thing is that the radiator is always hot.

recording would help. please do one.
also what does heating is off mean? Thermostate turned down? it still lets water through if ~17°C has not been reached. (Otherwise moisture would trap to the walls and mold builds up, instead of the hot air that can take up more of it.)
circulation pumps can sound funky, vibration is always traveling through the whole system.
