You would add it to the boiler
Typically a baseboard heating system. Consisting of a boiler, pump, piping, and a heat exchanger like aluminum fins.
Add more water
keep water off of it.. that is about as much as you can add to it
Use baseboard heaters and an air conditioner.
Just add enough water.
Yes. You might want to check to see what recommended temperature is for water entering the baseboard units and insure the water heater will meet that. Something else to consider is that there will need to be a pump in the water circuit to circulate the water. A tank type water heater would also work to store hot water until needed by the baseboard units in an instance where heat might be generated at a time not needed by the baseboard units.
Yes, 1/2 inch supply to fill boiler will work fine. Piping going to baseboard heaters needs to be sized properly. 1/2 inch piping to baseboard heaters not recommended. Most hot water baseboard heaters piped with 3/4 pipe.
sometimes
About 150 deg.
Same as you would do with a gas Boiler BUT remember a furnace does not have waterThe type of furnace that uses baseboard radiators is a hot water furnace. Most have bleeder screws at one end of the rad. If you loosen this screw while it is heating it will allow the air to escape. When water starts with no air hiss tighten the screw. If you do not get water, just air check the water pressure guage on the furnace to ensure there is water in the system
120-160 Degrees Fahrenheit
A bleeder valve to remove air in the system
That means there is air in the lines and must be bled out.
A baseboard can be 3/4 inches
A baseboard heater runs through a process of induction and release, in a manner of speaking. That is, the burner will heat the water; the water will pump through the system; and once all is up to temperature, the burner will shut down. However, the metal of the pipes and the water itself will not cool right away; it will remain hot for a time and cool slowly. The closer the baseboard is to the furnace itself, the longer it will remain hot.
the baseboard is called 'une plinthe' (fem.) in French.
Yes, electric baseboard heaters can be painted.
