Substations for direct heating have no heat exchanger separating the primary flow from the secondary flow. Therefore the supply from the network or the central oil-/gas boiler will flow directly into the network in each flat. Direct substations are recommended for maximum PN10 or PN6 networks.

Quite simply, direct heating technology involves a bulk solid material coming into direct contact with a heating gas to change the final temperature of the material. On the other hand, indirect heating technology does not allow the product to come in contact with air or gas or any other heating agent to change the final temperature.

Direct fired heaters in industrial heating systems Basically, we can understand them as the definition of an oven. The heat is directly transferred to the product of the process, basically hydrocarbons or chemical solutions. For this reason, in petrochemical plants or petrol industry refineries the expression Process Heater is sometimes used.

Boiler - an overview | ScienceDirect Topics

Boilers are heating-system components designed to generate steam or hot water for distribution to various building spaces (Figure 9.18). As water cannot be used to directly heat a space, boilers are only used in central systems where hot water is circulated to delivery devices (e.g., baseboard radiators, unit heaters, convectors, or AHUs). Once the delivery device is heated with hot water, the water is …

Comparing Indirect vs Direct hot water systems - Hamworthy …

Direct fired water heaters are solely dedicated to the job of hot water generation, providing a faster heat up and response time compared with an indirect system which is in fact ‘heating water to heat water’. This increases the chance of heat losses in the boiler, and associated pipework between the boiler and calorifier.

Boilers are special-purpose water heaters. While furnaces carry heat in warm air, boiler systems distribute the heat in hot water, which gives up heat as it passes through radiators or other devices in rooms throughout the house. The cooler water then returns to the boiler to be reheated. Hot water systems are often called hydronic systems.
