Dec 23, 2010 · The high efficiency condensing boilers rely on hot water that is approx. 90-120 degrees to burn a high percentage of their fuel, but to take advantage of this low-heat process, the low-heat BTUs have to be stored in a LARGE MASS RADIANT EMITTER, like the ENTIRE FLOOR, OR LARGE BLOCK OF CONCRETE over a LONG PERIOD OF TIME, like 8 to 24 hours---in effect, the entire floor of the house becomes one large radiator, heated to 120 degrees over an 8 hour period---once this occurs the floor gives up
In water-tube boilers, the water is contained in tubes located inside a furnace and hot flue gases pass over the tubes, heating the water, and then exit out the stack. While both steam boiler designs offer comparable efficiencies, they are not interchangeable. This is primarily due to structural considerations.

Jan 23, 2018 · Boilers are commonly made from steel or cast-iron, and use “fire tubes” which carry hot combustion gases. The burner uses fuel (usually gas or oil) to send hot gases into the tubes. The heat from the tubes get transferred to the water, which is then pumped into the radiators. A flue pipe will vent the exhaust gases out of the home.

Oct 12, 2016 · Both steam boilers and hot water boilers (also called hydronic boilers) involve the heating of water and creation of steam through the burning of fuel. The heated water is transmitted through boiler tubes, while the steam created is circulated throughout the facility with the assistance of radiators.
As their name implies, the key to a water tube boiler is a series of tubes that sit in the middle of the boiler. The tubes are roughly the same length of the boiler and designed to withstand great amounts of pressure so that they don’t crack or leak. When the furnace is lit, hot gas flows throughout the boiler, heating up the water inside the tubes in order to create steam.
