The boiler 'water' will actually contain a mixture of water and steam bubbles, which will be less dense than water alone. If the demand for steam increases, the pressure in the boiler initially falls, and the control system will increase the burner firing rate.
Assuming you have a cold water pipe nearby to tap off of, proper installation will include a backflow preventer, a pressure regulating control valve with expansion tank in the line leading to the boiler, and an air bleed vent on the line where it leads into the boiler - so probably in the order of $100-200 materials, plus $125-200 labor

New Boilers Could Mean Less Water Capacity. An old cast iron 200,000 Btuh steam boiler may have had a 40-gallon capacity. Today's modern, efficient boiler of the same heating capacity may only have 7-8 gallons of water when filled to the proper level. Both boilers will lose water at the rate of about ½ gallon per minute.
Fire tube boilers are useful for small demands of steam and water tube boilers are useful for industrial level usage. To cut short the main purpose of boiler is to boil a liquid mostly the water in order to generate the steam for serving the purpose of heating a building or running an equipment through pressurized steam or pressurized water.

Steam boilers tend to be steel water-tube- or fire-tube-type boilers in the 10-to-1,000-hp range. Fire-tube boilers are more robust and more tolerant of poor water quality, but require more physical space, than water-tube boilers. Regardless of boiler type, water quality is a critical aspect of implementing and operating an efficient steam plant.
