Jun 18, 2014 · Convert that radiator to hot water and you're only going to get about 150 Btuh out of that same square foot of radiation. So, for instance, if you have a five-tube, 26" high, 10-section, cast-iron radiator running on steam, it will emit 8,400 Btuh. Convert the system to 180- degree hot water and you'll get only 5,250 Btuh out of that radiator.

To move CFBC technology to advanced steam cycle conditions, boiler manufacturers are adopting once-through boiler technology in the designs of supercritical CFBC boilers (Zhu, 2013). A key to the design of once-through boilers is to sufficiently cool the furnace enclosure tubes to avoid overheating under all operation conditions and to minimize the tube temperature differences between the adjacent tubes ( …

Steam-based heating systems are common in New York City, especially in pre-war apartments and other old buildings. However, steam boilers and radiators tend to be inefficient due to their age and design, and conversion to hot water can yield considerable energy savings. Other than being more efficient, hot water systems also offer a faster response time than steam radiators, while having reduced maintenance …

Converting from steam to hot-water heating is not a trivial process. It will require a significant investment in planning, system modification and new equipment, including a boiler. There are three major factors that usually drive the decision to change to hot-water heating: Cutting annual operating costs: Hot-water heating can be much cheaper and more efficient than steam heating. Newer high-efficiency boilers can reduce operating costs by a significant percentage, making hot-water …
