HVAC Hot Water Heating Systems | Old House Web

Boiler. Most hot water and steam heating systems have steel boilers with a service life of about 20 years. Cast iron boilers, which are less common, have a service life of about 30 years. Old cast iron boilers converted from coal fired units may last much longer but are usually quite inefficient. Inspect all boilers for signs of corrosion and

Water-tube boiler - Wikipedia

Water-tube boiler. Cool water at the bottom of the steam drum returns to the feedwater drum via large-bore 'downcomer tubes', where it pre-heats the feedwater supply. (In large utility boilers, the feedwater is supplied to the steam drum and the downcomers supply water to the bottom of the waterwalls).

Recirculating Systems for Hot Water & Heating

Using either pumps or natural convection (in a passive system), recirculation systems advance the flow of hot water from your boiler or water heater through your home and back to the heat source. These systems are most commonly used in radiant floor and baseboard hydronic heating, or to reduce and even eliminate the wait for hot water in fixtures around the home.

Water-tube boiler - Wikipedia

The older fire-tube boiler design, in which the water surrounds the heat source and gases from combustion pass through tubes within the water space, is a much weaker structure and is rarely used for pressures above 2.4 MPa (350 psi). A significant advantage of the watertube boiler is that there is less chance of a catastrophic failure: there is

Water Tube Boiler A water tube boiler is a type of boiler in which water circulates in tubes heated externally by the hot gases / flue gases. Water tube boilers are used for high-pressure boilers. Fuel is burned inside the furnace, creating hot gas which heats up water in the steam generating tubes. Types of water tube boiler Babcock Wilcox boiler, Sterling boiler etc.

Heating the Water - How Water Heaters Work | HowStuffWorks

How Water Heaters Work. Water exiting the water heater at the top is always the hottest in the tank at any given moment because it's the nature of hot water to rise above denser, cold water. The secret to a water heater's design for separating cold, incoming water from hot, outgoing water is that it relies on the principle that heat rises

Understanding Steam & Boiler Heating Systems | HomeAdvisor

Boiler Systems Operation. In steam heating systems, a boiler furnace heats water by means of a gas or oil-fired burner and turns it into steam. The steam travels through pipes to radiators or convectors, which give off heat and warm the room. As the steam cools, it condenses back into water, and returns to the boiler to be heated again.
