Flow control valve that will over come stratification of hot water flowing through the system until a circulator comes on
For a while IF the boiler has an automatic low water cut off and other safety devices but if any fail you will have a melt down and an explosion
have baseboard heat boiler runs off furnace want to shut off furnace to save oil will it hurt anything
When it achieves the maximum temperature, it shuts off. Then when there is demand for the water, or it is at its low setting, the boiler fires up again until it reaches the maximum temperature set.
On any water heater, the shut off is on the incoming cold pipe.
If you have hot water heat or steam heat, it will still work. Gas or electric heat has nothing to do with the water system.

Yes, shut off water to entire residence if residence totally dependent on electric, including heat. If residence heated by hot water or steam heating system, water needs to be ON to boiler for heating system. Anything else that has water going to it can be turned off if it has a separate valve for it. Electric water heater should have power turned off and gas water heater should have gas turned off. Outside hydrant hoses should be disconnected.
Connect the domestic coil thru a tempering valve to the hot water pipes in your house and turn off the valves to your old hot water heater. You should include a shutoff valve so you can revert to the hot water heater when you have your coal boiler shut down.
Hot water heat is typically a closed system, and the pressure gage is used to determine if the system is full of water. Loss of water in a closed system will create air gaps in the water flow, and the boiler is not capable of heating air. Low water level arriving back to the boiler will trigger the high-temp shut off switch, and the water will not become hot. Add water to the system and check the gage. To add water, open slightly the system drain valve (should be located in a pipe at the top of the system) and fill the system thru the inlet valve with a hose from a faucet until the spray from the open drain valve is solid. Close the drain valve system, and then close the inlet valve. Close the faucet valve and remove the hose.

Capresso water kettles heat can be purchased starting as low as $60 depending on the model. Capresso water kettles heat up water quickly and are equipped with an auto shut off. They are not only a convenient way to boil water but they look great as well!
The combustion air will not be able to go out the chimney. Since it has to go somewhere it will leak out the boiler into the boilerroom. If the boiler is air tight the pressure inside the boiler furnace will become high enough that the air will surge or run backwards out the forced air fan. This could lead to combustion outside the boiler, explosion or at least filling the boiler room with smoke and poisonous gasses. The flue on our gas fired hot water system once became jammed shut. It was the smell of incomplete combustion that alerted me to a problem. If it had happened when everyone was asleep or no one was home, the house would have filled with carbon dioxide.
