Steam boiler VXt progammed water feeder

I had rushing water through pipes from my burnham steam boiler. A plumber advised me that my programmed water feeder malfunctioned and needs to be replaced. He thought it unusual that the water was rushing rather than a stoppage by the water feeder. the boier was installed in 2002.
I was looking for other opinions on the matter.

thanks

thee probably a way of attaching a pipe to the outlet and directing it down into a bucket of water or into a drain pipe or sewerage pipe
might be best to get the people who installed the unit to come back and advise on a good solution

Hot Water Steam Efficiency Plus Comfort


Steam heat is a great warm, wonderful, and absolutely fabulous way to heat your house. Steam heat is almost always created from water in a boiler fueled by gas, oil or electricity. It then passes through pipes and radiators or convectors to heat your home. A steam heating system uses steam that is generated from a boiler. When the water boils, the steam rises through the pipes and into the radiators to heat them. The hot radiators then heat your home.

Steam is a great heat distribution medium because it moves easily through your system and it has an extremely high heat-holding capacity. The heat-holding capacity of steam is much greater than that of water. Steam heating systems often operate at very low pressures and usually under 220°F. Steam heat is usually distributed by either one or two pipe systems. In a case of a one-pipe steam heating system, a single main serves the dual purpose of supplying steam to the heat exchanger and allowing condensate to run back from the radiators also. A two-pipe system has two connections from each heat exchanger or radiator. In this system, steam and condensate flow in separate piping from each other. With a steam system all pipes must be well insulated and you must use pipe insulation rated for steam piping. If the insulation is removed the system will no longer work as designed. Noise and all sorts of problems will come from uninsulated piping.

When you have radiators on upper floors or radiators that are further from the boiler they should be adjusted to release more air to compensate for the increased air volume in the piping due to the distance from the boiler. If you have a valve that is clogged with mineral deposits or stuck shut, no air will be able to get out of the piping. Because of this no steam can enter the radiator, so it doesn't heat up. This will block the movement of steam into the radiator, or cause a very noisy hammering as pressurized steam tries to get through this water "dam".

Steam radiators need to have a valve that allows air to escape at a controlled rate so that the radiator can heat up. Steam heating systems will also lose a little bit of water all the time, so there has to be water makeup so that you do not run your boiler dry. Steam heating systems without an automatic water feeder are not safe. You will risk serious boiler damage should boiler water be lost. If the boiler runs dry it could also explode if water is placed into it while it is hot. There should always be a low water cutoff installed on every steam system. Therefore on a steam boiler the automatic water feeder serves as a safety device also.

It is very important that you find someone that is very familiar with steam heating systems when repairing or installing steam heating. Incorrectly designed, installed, steam systems and condensate piping is a huge problem in today's buildings and facilities. There are not many qualified to design and install properly operating steam heating systems. Incorrect steam piping will always cause costly premature failure of steam equipment such as steam coils, heat exchangers, and control valves. Not to mention the higher cost of operating a system that is not working efficiently.

What is causing the water lines to pulse enough to rattle the house piping when the washer starts filling?


This is known as "water hammer" noise or the result of an explosive rush of water moving through your pipes with such force that a shock wave is created and leads to a banging noise that repeats itself. Sometimes this is called plumbers knock. There is nothing you can do about that other than change the pressure externally to reduce the rush.

I have a 10 year old Burnham Model 3WNH, and was told that I could get hot water for showering from it. Is this possible? I do see a 2 1/2" knock out on the back.


House hold hot water is a common addition to boilers. Some, not all have it as an option.

The problem I'm having with your question is the model number. I don't find that number anywhere. Can you check that again please?

I have a 5 -7 yr old burnham gas burner for steam heat. I am frequently needing to put more water than normal and notice the pipes bang now also,what do you think could be wrong? thank you


When was the last time the unit was drained and flushed? Also the feeder may be stuck closed if it has one. Check all the steam vents to make sure thay are letting steam out of them. If not, replace the ones that are not. The banging is thermal shock (Steam hitting cooler water in the pipes). For some reason all the water may not be draining back to boiler.

I have Burnham series 2 Boiler - I cant locate filter,see dust


Boilers do not filter air, as they heat with water.... Most boilers do not require home owner manitenance, unless your circulators need to be oiled

I'm a new plumber. I was asked to restart a burnham gas fired steam boiler in a fire damaged apartment. The boiler was drained last winter along with the radiators but was not winerized. I am their plumber...


1. You need to fill the entire system with water before you fire it, boiler AND radiators... Then, you would normally vent as much of the trapped air in the system as you could... It's not like you are only going to fill just the boiler and then pump that water through the pipes.

There is a temp setting on the boiler, but I don't think that's a solution. Remember that the water in the system is going to begin circulating as soon as you start the boiler. So, it will start circulating when it's cold, and then gradually warm up.

Your problem is not the sudden rush of hot water, it's going to be filling the system in the first place, and getting the boiler started before the system freezes up ...

I don't really have any suggestions for you though, other than perhaps renting one of those construction heaters ... and bring the building temp up a bit. But there's certain dangers associated with them too... Carbon Monoxide for one, fire is another (if used improperly).

Just thought of something: Fill the system with glycol based anti-freeze solution that's designed for heating systems. That oughta do it...

I'm guessing there's not a functioning water heater either at this point, is there ? If there was, you could possibly rig something up to fill the system with lukewarm water, and fire it before it freezes up.

2. You don't have a lot of choice. You have to fill the system, fire the boiler & wait.
It is going to take a long time to get the system up to temperature. Instant circulation is a double edged sword. The upside is you get a little bit of heat into the water & have it moving making freezing less likely. The downside is, it's hard on the boiler with that much cold water coming back you are likely to have condensation.
