There is a key similar to those on radiators on the boilers than can be turned round with an adjustable wrench etc.

heating ventilating and air conditioning.Type your answer here...
Does not sound like central heating. It sounds like a boiler system. When the hot water is routed through the cooler pipes and radiator, the air in those pipes are pushed through begins to expand and it causes the same effect as a tea pot boiling on a much larger scale.
They serve two different purposes. An air bleed valve is used to remove air from the circulation system. A pressure relief valve is designed to automatically open when certain pressure levels are reached.
A hydro-air heating system is a type of heating system that combines hot water and air to distribute warmth throughout a building. It uses a boiler to heat water, which is then circulated through a heat exchanger or coil, where air is blown over the heated surface to warm it up. This warm air is then distributed through ductwork to various rooms. Hydro-air systems offer efficient heating and can be integrated with existing air conditioning systems for year-round climate control.
By using the bleeder valve by the boiler
Bleed the accumulated air out of the system. I did it twice a year, to improve heating efficiency, and eliminate banging noises.
Possible air lock in the heating pipes. Common after changing thermostat. look for a bleed screw on the heating pipes between the engine and interior, or loosen one of the heater pipes., after engine has warmed up. Run engine to dislodge trapped air.
A home heating boiler is a woodburning water heating system that can potentially save you money on natural gas. If you cut your own wood and have an ample supply to burn, then a home heating boiler might be a great cost effective option.
In a boiler system you raise the static pressure via the fill valve to 25 psi (on a 30 psi system) and circulate the fluid. If there are air eliminators in the system, you would crack them to allow the air to escape.
Because it has air in it.
its easy if you do this they wont you to make a line for the pipes so they go in a line to the boiler so you can get air into the boiler
Bleed it /Purge
yes
None. Probably the home was built for forced air and converted to boiler/baseboard heating.
Probably pockets of air in the plumbing. Do you have hot water radiators for home heating ? If so, you must bleed the air out of the units and the main boiler.
Yeah. sure, why not?
