But it's only to assist in heating the water of the already exisiting hot water heater. For systems with reheating, the heat that is obtained from coal or any other fuel is always less than the heat that is available for the steam. The higher the air temperature rises above typical levels inside the house, the slower it loses energy. Fixed range of coolant or water spray flow rates, 7. But in a basement where the heat may be limited, one could end up with a cold, dry basement and higher energy costs due to a lack of heat for the Geyser to absorb. What Temperature to Set the Thermostat at in Winter. Water is the fluid used as a coolant in the case of superheated steam. When the temperature of the steam is higher than the saturation temperature, then the state of the steam is referred to as superheated. The two fluids are mixed at controlled measures to obtain the steam at specific pressure and temperature. In residential or domestic water heating using desuperheaters, the heat during the summers is used for heating the water. PDF Desuperheater Connection and Plumbing Installation Desuperheaters are installed for the effective performance of heat transfer between steam or vapor (saturated, superheated) and water.
