So my installer has 200 plus installations (supposedly just like mine) minus the Rheem Marathon electric hot water heater as they are using conventional (not Rheem Marathon) electric hot waters instead. The desuperheater helps in lowering the high temperature of the steam to low temperatures that will help in safely carryout the other process operation. The gas water heater is only a year old so I don't know. Turn off the water to the building. I suppose someone could also increase the lower thermostat setting (closer to the upper thermostat setting) until the geothermal/desuperheater runs more (due to it being colder outside), and then reduce the setting again to get more benefit out of the desuperheater. Downstream to the valve, it is suggested not to rise the piping alignment to avoid the collection of condensates. The heat from the superheated steam passes into the coolant through the heat exchanger. Programmable thermostats are less helpful and may actually prove more costly for people who rely on heat pumps to warm their homes. Gas fired water heaters and desuperheaters do not play well together. LWP - Leaving Water Pressure (top line) 49 psi. This button is in the middle of the page. Dampen som brukes i dette systemet er enten fersk damp eller damp som tappes. It also means checking that vents and radiators are not obstructed and that air ducts and heating pipes are properly sealed [source: Department of Energy].
