Furnaces heat air and distribute the heated air through the house using ducts. Boilers heat water, and provide either hot water or steam for heating. Steam is distributed via pipes to steam radiators, and hot water can be distributed via baseboard radiators or radiant floor systems, or can heat air via a coil.
2003-10-30·Water boils under constant temperature and pressure, so a horizontal line inside the enclosed region represents a vaporization process in the T-s diagram. The steam/water heating process in the boiler represented by the diagram in figure 2 can also be drawn in a T-s diagram (figure 4), if the boiler pressure is assumed to be e.g. 10 MPa.
The other primary option for using a heating system to produce hot water is to install an "indirect" or "indirect-fired" water heater. This is a separate insulated water tank that is heated using hot water from the gas- or oil-fired boiler. The indirect tank is usually plumbed to be a

HMR HMT HM2 boilers with integrated by-pass are designed for installation on any type of distribution (piping) system that is equipped with a circulating pump such as finned tube baseboard and cast iron radiators as shown in Figure 4.
2009-10-1·Boiler-system efficiency is one of the most documented and published topics for plant engineers and utility managers in commercial and industrial facilities. Understandably, with gas and oil costs at $6 to $10 per million British thermal units of fuel energy value, boiler fuel can represent 30 to 50 percent of total energy budgets in plants with large thermal loads.
District Heating Conversion from Steam to Hot Water
2015-6-23·District Heating Conversion from Steam to Hot Water at the Savannah Regional Hospital In 1992, the Georgia Department of Human Resources decided to replace the steam and chilled water distribution systems at the 16 Building Savannah Regional Hospital in Savannah, Georgia. Each hot water boiler has an automatic control system which

Boilers are part of a hydronic heating system. Hydronic systems use water to transfer heat to a distribution source, like a radiator, to heat a home. Hydronic systems can heat via hot water or steam, depending on the type of boiler used. The boiler is the part of the system that heats the water
Modular heat distribution unit for hydronic heating
2007-8-16·4. In this embodiment, the hot water source is a boiler 56. The boiler 56 supplies hot water to the modular heat distribution unit 50, which regulates its circulation to the tubing 58 supplying the hot water to the baseboard panels. An optional indirect water heater 60 is also shown in this system.
2019-7-24·Furnaces have the advantage that the greenhouse can be closed during the winter without having to drain a series of water pipes as is the case with a boiler system. Hot water systems In larger greenhouses, hot water is a better medium of heat distribution than air.
Design Considerations for Hot Water Plumbing - CED

Example: shower, urinal, fountain, shower, sink, water faucet, tap, hose bibs, hydrant etc. fixture unit on the cold water system, and 1½ fixture unit on the hot water. Supply piping
2011-5-14·By far the largest energy loss in a boiler is attributable to the hot flue gas leaving the stack. Thus, the most effective method to save fuel is to recover as much sensible and latent heat of water vapor condensa-tion in the flue gas as practicable. Additional benefits of this energy recovery are: 1.
