Dec 01, 2015 · Mar 13, 2012. #9. Most condensing boilers condense for longer when the return temp is around 55 degrees. Ideally you want to keep it condensing for longer, for energy efficiency. So the way that I always do it, when setting up a new system or balancing an existing system is: Add the differential across the flow and return onto the 55 degrees,

For a modern combi boiler, the radiator heating temperature should be set at or around 75 degrees celsius for the best efficiency and performance. In summer, you can consider reducing the boiler's radiator temperature setting to around 65 degrees celsius, as this will provide additional efficiency at the cost of heating performance. As an additional note, this temperature setting refers to the temperature …

In the case of a boiler fueled by digester gas the condensation will contain water and sulfurous acid. A stack temperature that is well above the dew point can generally be maintained if the boiler water temperature is above 160 degrees F. The Walker Process boiler water temperature is maintained between 180 – 200 degrees F.

Traditional boilers yield saturated steam that can sometimes be mildly superheated. Thus boiler steam may be wet and contain water droplets. For example with a boiler one needs a high 10 Bar and even then the saturation temperature is only 180°C – even at 100 Bars the saturation temperature is only 311°C.

An increase in stack temperature can indicate to boiler operators that soot and scale is building up. According to Muller et al., a 5 °C rise in stack temperature indicates a 1% efficiency loss (Muller et al., 2001).The optimum temperature of the stack should be the readings immediately after the boiler has been professionally serviced and cleaned.

The role of high temperature in water heater lime and scale formation also explains the rapid clogging of tankless coilsused for domestic hot water production. Residential heating boilers regularly operate at temperatures between 180 degF. and 200 degF., causing rapid scale formation where hard water is passing through the tankless coil.

a temperature rise of about 20°F to 40°F depending on model, pump, and piping configur ation. If the system is set to provide a 120°F supply, the water temperature inside the boiler's heat exchanger may reach 140°F to 160°F. As flow rate is reduced the water temperature inside the boiler will increase. This will increase the rate of lime

Scaling mechanism is the exceeding of the solubility limits of mineral substances due to elevated temperature and solids concentration at the tube/water interface. The deposition of crystalline precipitates on the walls of the boiler interferes with heat transfer and may cause hot spots, leading to local overheating.
