That makes sense...if you have a leak every year.

When you install a boiler, bleed the air, and heat the water, you'll release air from the system one time. After that, how does new water enter the system? It shouldn't, unless there is a leak.


@ October 1, 2012 10:14 PM in Induction as a heat source for steam?

You're right. I added an extra 1 by accident.


@ October 1, 2012 9:53 PM in Induction as a heat source for steam?

Electricity is 100% efficient, but damn expensive. My boiler would cost about $35 an hour to run.


@ October 1, 2012 8:26 PM in Recently installed replaced Steam heating system

The boiler needs to be skimmed and cleaned. Was it installed in black pipe or copper?


@ October 1, 2012 6:34 PM in Buderus Pressure

That is bad information. How did he test for leaks?

Where do you live? I'll hire you!


@ October 1, 2012 6:29 PM in skipping annual maintenance of steam boiler

Would you stop brushing your teeth and showering for a year?

They'll spend more money fixing two broken boilers next year than taking care of them this year.


@ October 1, 2012 4:04 PM in PRV's and new boilers

To me, it's part of the new boiler. If you don't change it, and it breaks, it's "your fault" in the eyes of the customer.


@ October 1, 2012 8:41 AM in Only one radiator working in home

Welcome to the world or Radiator Balancing. Change one, affect another. You should really asses every radiator and vent in the system. If you post measurements of each radiator and the approximate length and size of their supply pipes, we can tell you which vents bleong on every radiator


@ September 30, 2012 8:11 PM in New House with steam system not behaving

It does need to be a double swing damper for safer operation, but the boiler should still run the same.

You can try to prop the damper open a little and see how that affects the operation. Checking the flue temperature can lead you in the right direction.


@ September 30, 2012 7:09 PM in New House with steam system not behaving

Picture was misleading.

There should be markings 2,4.6,8. Those are draft settings. If it's maxed out at 8, that may be too high. You can adjust it down to 4, but it'll be impossible to tell the real draft numbers and affect on the system without doing a combustion test.


I see that it is set at about the 2 marking, so that "shouldn't" need to be adjusted.


@ September 30, 2012 6:41 PM in Getting butt chewed for this. Sould I?

You only size the pump for the highest restriction in the system. The other loops will work because they have less restriction.

The pump does not push anything up or down, it only moves water that is already there. Your static fill pressure will maintain water and pressure up to the second floor.


@ September 30, 2012 6:14 PM in New House with steam system not behaving

I'm still leaning towards a possible high draft condition. In the one picture, it looks like the draft control damper is slammed right up against the return pipe. Not much room for movement or service.

If the damper is closed, the draft will higher in the boiler. Maybe too high. When the draft is too high, it will draw more heat out of the boiler and out to the chimney. That could explain the unusually long run times.

Shoot your laser thermometer on the vent connections before and after the draft control. See what the temperatures are with the damper open and closed.


@ September 30, 2012 6:07 PM in soldering problem

Dd you clean and flux the pipe?


@ September 30, 2012 2:41 PM in New Boiler, and Problems

I would suggest installing a ball valve on the return near the boiler, and flushing all of the returns out until they run clean. Seems like you are getting a lot of old sludge back in the boiler. And please...make the plumber stop adding anything to the boiler! It's not working!!


@ September 30, 2012 11:44 AM in Why Real Steam Pros Don't Use Copper for Steam Piping

...and well said. You really do need a superior imagination to do this kind of work. In that way, it really is an art.

Gas valve

@ September 30, 2012 11:42 AM in Looking for old furnace conversion parts

Definitely post a few pictures of the controls. You may be able to update just the gas valve and safeties.

System bypass with balancing valve

@ September 30, 2012 9:05 AM in System bypass with balancing valve

If you install a cast iron boiler with a system bypass, like the Danfoss Thermic Valve, how do you detrmine the correct flow rate for the bypass?

For what it's worth

@ September 29, 2012 10:08 PM in Getting butt chewed for this. Sould I?

Do the job any cost.

@ September 29, 2012 9:34 PM in Mystery relays

A lot of information in there to process. Do you have any pictures of the relays, with and without the covers on? Maybe some of the other parts, too.


@ September 29, 2012 7:54 PM in Trying this again . . .

Yup. Power off. Switch the breaker if you're not sure.


@ September 29, 2012 6:19 PM in Header, I don't need no stinking...

I see this in every house in Bergen County, NJ. Too many plumbers...not enough heating guys.
