How Do Indirect Water Heaters Work? - New York Engineers
In this system the commercial boiler provides heating for the air in the building while also providing hot water for the buildings faucets and fixtures through the heat exchanger. Indirect water heaters work most efficiently during cold months when the heating
Comparing Indirect vs Direct hot water ... - Hamworthy Heating
Direct fired units such as Dorchester water heaters for hot water generation have an integral gas or oil burner that directly heats the water in its storage cylinder by supplying hot gases through one or more of its heat exchanger fire tubes within the cylinder which then transfers heat to the surrounding water. fired units such as calorifiers have no integral burner but contain one or more
Dec 09 2019 · Direct and indirect heating represent the two types of open vented hot water systems: Direct heating in this case the water is heated directly from the heat source using a boiler or via an immersion heater. Indirect heating in this type of hot water system the central heating and the hot water are detached.
Oct 02 2020 · Indirect heat transfer results in a higher quality final product as the bulk solid does not come in direct contact with air or fluid eliminating the risk of contamination. The slow controlled downward flow through the indirect heat exchanger plates also prevents abrasion and degradation to the material so there is no change in the final materials characteristics.
