Down Firing Cure for Steam Short Cycling?

Mad Dog_2

Plugging a burner is NOT the best approach and in many cases is downright foolhardy. Anyone who touches this system becomes liable and BETTER know what they are doing. Mel, we are very close by, and can make a field visit, but I cannot guarantee you of anything without seeing it. We do have a consultation/assessment fee. You can email us privately and I'll fill you in. Just keep in mind, we do things right and with safety first and we charge for that. Also keep in mind we may recommend a smaller boiler too. We're here if you would like to talk. Mad Dog

Down-Firing Cure for Steam Short Cycling?

Since we created a 2 zone system and reduced the number of radiators on our natural gas-steam system from 10 to 7, it has been short-cycling. It satisfies the pressuretrol well before the thermostat, taking less than a minute to do it once the system has been on for a while. Eventually, though, the house does get heated up. One suggestion has been to "down-fire" the system. Does that mean simply to turn the gas feed valve down and reduce the flame size? Is that likely to help?

Thanks for any suggestions.

I guess what I meant to suggest is turning the gas down at the pressure regulator adjustment on the combination gas regulator which in my case is a Honeywell VR8200A.

Have a pro do that

you don't want to adjust anything without being able to test it using a digital combustion analyzer.

DeRating equipment

Generally a change on orifice size is the proper way to do it. Also combustion tests must still be performed so you know for sure that the equipment if firing properly.

Also experiencing short cycling

I'm experiencing the same problem in Indiana, and am wondering what type of "pro" (gas company or possibly a commercial heating contractor in lieu of a home heating contractor) would one call! This must be quite common towards the east, but not in my area per those that I have asked.

Crucial to get a gas heating expert - with credentials

and recommendations, AND a combustion analyser, to tackle that. Very serious stuff. Mad Dog

OK I'm Convinced. How Much Will It Cost?

OK. I'm convinced. How much will it cost? And How do I find a professional who can do it right? I live in Northeastern Queens, near the Nassau County line.

One way is to remove a burner and plug the orifice at the manifold.

Sounds interesting. Looks simple. There are six burners on this 150 btu W-McL gas boiler. Is this a DIY project? Can it be done without making any adjustment on the gas regulator? Is there a small piece of hardware to plug an orifice with?

Thanks,

Mel
