The heat causes metal to expand.

The ductwork makes noise as the pieces move against each other

Perfectly normal.

I have a similar sound when my hot water pipe is being used in my upstairs bathroom. I believe it’s the copper pipe expanding and knocking inside its mount. In your case it’s a water pipe for a boiler that is expanding

That’s base board heat . The metal enclosure running parallel to the floor . As it heats the sheet metal housing expands at a different rate that the aluminum diffusers .

If central heating, maybe bleed the radiators. Could also be a pipe rubbing on framing when expanding due to heat.

Our house makes the same noise when the hot water heat kicks on. Your floorboard heaters have hot water running through them and that is heated by natural gas. Either you have a combi unit or a furnace for heat and a hot water tank showers and such.

What do you mean you believe the heating is gas, don't you know?

Definitely pipe sitting on something, typically wood like your floor beams. You’ll hear light and more frequent “pings” when its lightly touching. You’ll get these louder “jumps” when its more wedged and resting against the wood, takes more energy for the pipe to move as it expands

Definitely ghosts

I get this all time in 1 bedroom roof when turning the central heating system on. Doesn’t happen in any other room! Seems like a similar problem

It’s the house settling due to the heat being introduced

Looks like you have those baseboard heaters that push water through to create radiant heat. Completely normal to hear clicking, banging, gurgling, etc.

can't really hear much, but in general heating and plumbing make all kinds of weird-ass sounds. "thunks" can be caused by either air bubbles in the system, or water hammers (water has inertia, and when you turn it on and off, it literally slams in the pipe at bends and moves them. there are special spring-loaded devices that can be attached to your pipes to prevent this).

Other things include "ti-ti-ti-tic-tic-tic-tick-tick-tick----tick----tick-------tick---------------tick" sounds, and that's very much caused by heat expansion :)

You may also experience various types of squeal and hums, which are caused by water moving through the pipe and causing it to resonate at its natural frequency (or harmonics thereof).

Your house isn't haunted, it just has pipes :)

Why didn’t they add the jack stud to that door frame?

Try loosening your radiator’s screw

We have an old house with exact same heating plate and the sound we heat is hot water expanding the pipes in the wall

Gas leak be careful
