What is a Drop Header? - Heating Help

Jun 24, 2014 · Once you do a drop header you will never probably ever do it otherwise. Lyle Carter replies: I've found that when I'm using an indirect water heater with a conventional steam header on a steam system that when the indirect calls for heat I can feel the steam heat in the mains, sometimes 10-15 feet away from the boiler, which means that we're

What Your Boiler Pressure Should Be When It's Heated

Dec 30, 2019 · Pressure Change Range. Pressure will change when the unit fires up the heat. In most cases, it should rise to about 20 psi while its heating element operates. That's optimal at normal temperatures. Pressure changes of a few psi one way or the other can be brought about by atmospheric conditions. Most boilers are safe up to around 30 psi, at

Steam Pressure Reduction: Opportunities and Issues

Boiler Blowdown Loss. When boiler pressure is reduced, the blowdown loss is also reduced. If the energy from blowdown is being . recovered through a blowdown heat recovery system, there will be no further savings by reducing the boiler pressure. If however, blowdown water is being drained and flash steam is being vented, savings will result

Boiler Pressure Problem #1 Best HVAC Troubleshooting Tips

If this happens, the boiler pressure is affected by pressure from the domestic coil. In this case, the domestic needs to shut off and replaced. Another option is to abandon the domestic hot water coil in the boiler and use a water heater. Sometimes, domestic coils link into an indirect water heater meaning a storage tank that holds the hot water.
