Steam heating is popular in nyc buildings for a very simple reason: steam rises by itself, which made it a practical medium to deliver heat before electric water pumps became widely available. In new constructions, hot water systems with hydronic piping are by far the best choice, both in terms of efficiency and environmental impact.
12 steam and hot water heating free from leakage at its joints when expansion due to heavy fir- ing takes place. Boilers built in such a manner as to allow each each part of the boiler to expand under such conditions, are likely to be free from the possibility of the cracking of casting or sections.
Hot water heating is more efficient because it's easier to control. Steam will take the path of least resistance and sometimes you'll find in older steam applications that there are a lot of hot and cold spots.

The steam or water travels through the radiant baseboards, radiator pipes or pipes located in the walls or floors.
Both steam and hot water have their place in commercial food production and in the right circumstances, both can be great heating sources for your food production process. And thanks to portable electric steam and hot water generators, food processing operations of all sizes can have access to both steam and hot water for their cooking processes.
Steam is one of the most common and effective heat transfer mediums used in industry, but it is not the only medium available. Other fluids such as hot water and oil are also used for indirect heating in heat exchangers. The following series of articles will focus on the advantages of using steam compared to hot water or oil for heating.
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.
Then, the steam is pumped through the pipes until it reaches the radiators and produces heat for the rooms in which the radiators reside.

Most of the steam or hot water heating systems furnish comfort to people in homes, offices, and industrial buildings. A much more specialize application of steam or hot-water heating would be called process heating used in industry. We will be only be concerned with the comfort application is this article.

A steam to hot water generator is nothing more than a big heat exchanger where at one end steam is delivered and at the other end, water is delivered. As the steam runs through the exchanger it exchanges heat with the steam heating the water. Thus, producing hot water for domestic use and heating use in the winter.
4, a practical application would be the metal wall of a heat exchanger tube or plate which uses steam on one side to heat water on its other.
Keep in mind that one-psi steam in a radiator will bring the surface of that radiator up to 215 degrees. Hot water, by comparison, is usually only about 180 degrees, tops. Convert that radiator to hot water and you're only going to get about 150 btuh out of that same square foot of radiation.
Steam and high-temperature hot water systems are typically found in large facilities because the higher energy intensities keep equipment and piping sizes smaller. For some commercial, health care and industrial facilities, the steam may also be used for other purposes as well as comfort heating.
Steam boilers provide the most flexibility for heating because they can handle high pressure process loads, as well as heating water and air for low pressure applications through steam-to-water or steam-to-air heat exchangers. However, they are limited to 15 psig design pressure, at a minimum.
Here's how a pro can add a hot-water zone to your steam-heating system. It's partially filled with water and it uses the space above its waterline to make steam, which then races off into the piping in search of a way out (that being the air vents on the radiators and the vents near.
In manufacturing processes, where direct heating is not possible, a heat transfer medium is used. Steam used to be the only choice as water was easily available at low cost and resulted in very few environmental issues. The heat required to convert liquid into vapor without changing its temperature.
Both steam boilers and hot water boilers may share certain controls that monitor and manage the heating source such as an oil burner or gas burner. Heater burner controls make sure that there is a safe proper combustion flame, control draft, and protect against flue gas spillage.
Steam our steam commercial water heaters use steam to provide hot water. They feature maximum steam pressure of 150 psi, up to 7000 mbh input, and storage capacities ranging from 150-4500 gallons. Available in instantaneous and storage models, all water heaters are asme stamped.

There are many types of boiler applications, the primary ones being hot water and steam. In hot-water applications, boilers typically operate within a stable closed-loop system in which the water chemistry is fairly constant. This means water is treated and stabilized for use during the initial fill of the system.
I believe steam did come first since it was used for motive power primarily, then later used for heating inside homes once practical. Water was harder ot use as there were no pumps and you had to rely on gravity systems with oversized pipe that offered little advantage over steam other than more mass.
For efficient heating, the water in a hot water system is heated well above boiling, but it doesn't turn to steam because the expansion tank and a pressure-reducing valve keep the water under pressure. Usually the expansion tank is hung from the basement ceiling, not far from the boiler.
Hot water heaters are considered to be more energy efficient than steam radiators. This is because hot water heaters move the water through the system using a pump, which allows the water to move at a predictable rate.
Hot-water radiators are one of the most common heat distribution systems in newer homes, second only to forced-air systems. They are typically a baseboard-type radiator or an upright design that resembles steam radiators. The most common problem in hot-water systems is unwanted air in the system.
Steam-based heating has a long history as a reliable source of heating for commercial and residential applications. However, in some cases, converting from steam to hot-water heating may be a better choice. If you’re considering making the switch, here are some important points to keep in mind.
Heat loss from steam pipes - amount of condensate generated in steam pipes depends on the heat loss from the pipe to the surroundings; heat loss from uninsulated copper tubes - heat loss from uninsulated copper pipes - dimensions ranging 1/2 - 4 inches; heating water by injecting steam - water can be heated by injecting steam.
The steam heating system is made up of a water boiler, a burner, the pipes, and radiators and/or convectors. The way a steam heat system works is fairly straight-forward. The steam then travels through the pipes to the radiators and/or convectors in each room.
Direct hot-water heating a hot-water system is similar in construction and operation to one designed for steam, except that hot water flows through the pipes and radiators instead. The circulation through the pipes is produced solely by the dif ference in weight of the water in the supply and return, due to the differ ence in temperature.
