Boiler Condenser Outlet Temperature

Boiler Condenser Outlet Temperature

Condensing boiler - Wikipedia

A condensing boiler extracts additional heat from the waste gases by condensing this water vapour to liquid water, thus recovering its latent heat of vaporization. A typical increase of efficiency can be as much as 10-12%. While the effectiveness of the condensing process varies depending on the temperature of the water returning to the boiler

condenser is that economizers are primarily used to heat a smaller volume of water to a high temperature for boiler feed water, and condenser units heat a larger volume of water to a lower temperature. Condensers can be more efficient because they can

Of note, though, is that this boiler has three pre-set reset curves, the most aggressive of which has a maximum HWST of only 120 F and puts the boiler in condensing mode of the time. If you take the time to read the manual, you might find that you can do away with that pesky math or that clunky ruler by simply using an already built in reset curve.

6/8/2018 · These control the output temperature for the radiators and the hot water temperature. To maximise efficiency, we recommend setting your radiator dial to 75 degrees and your hot water to 60 degrees. Once you've got your boiler running at the optimal temperature, you'll want to set the timer for when you need heating the most.

Setpoint High Limit: Setpoint high limit allows for a selectable maximum boiler outlet temperature and acts as temperature limiting governor. Setpoint limit is based on a PID function that automatically limits firing rate to maintain outlet temperature within a 0 to 10 degree selectable band from the desired maximum boiler outlet temperature.

What is a gas condensing boiler? | Viessmann

In a condensing boiler, heat existing in the flue gasses can be captured and 'recycled' back into the heating system and used to preheat the cold water entering the boiler. During this process, the temperature of the flue gas is rapidly reduced from around 130℃ to 50℃. This fall in temperature causes condensation, from which the name is
