@ October 5, 2012 6:18 PM in NG fired steam boiler recommendation

Just finished this up today.

86.2% efficient. Going back on a colder day to make the final adjustments.


@ October 5, 2012 2:41 PM in converting oil burner to gas

You will either match, or increase the boiler's efficiency. The only way the efficiency goes down is if you do not install the gas burner correctly. So, do not use anybody who makes that claim.

One word.

I love my Testo 327. I will never use another brand.

End switch

@ October 3, 2012 9:21 PM in Utica boiler problem.

Try jumping the end switch to see if that works. If it does, the zone valve or wiring is bad. If it doesn't work, the zone board may have a problem.


@ October 3, 2012 9:18 PM in Looking for A/C and possibly new heating system

Do not cross over into the dark side of Forced Air Heating. Nothing but regrets will be had.

Install A/C. Update the boiler. Enjoy efficiency and comfort.

The high velocity systems are great for a whole house. Mini splits are better for select rooms, but not necessarily a whole house.

Smith. Carlin.

@ October 3, 2012 8:38 PM in NG fired steam boiler recommendation

I'm going to be installing a Smith/Carlin steam job tomorrow. I'll post my combustion numbers. I'm going to keep a log of every boiler I install this year.

Mm hmm

October 1. Greatest day of the year.

Second floor

@ October 2, 2012 9:12 PM in New House with steam system not behaving

The connection for the second floor radiators looks like a capital T? That could be part of the hammering problem. Do you know the EDR of the two radiators and the size of the pipe? You can also vent the common pipe as if it were a main.

Do you have a meter to check voltage?


@ October 2, 2012 8:34 AM in Buderus Pressure

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?


@ October 1, 2012 6:31 PM in Advise on my header before hooking up to the mains

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.
