If it's too much trouble to cut into the main, I will sometimes add a tee righ after the elbow that drops into the return. A few feet of the smaller size pipe is easier to work with, and less expensive than dismantling the main.

I figured that I would't be able to find resources for a residential level job. This customer could be a curse or a blessing for me. Good advice about over designing. I think I'm going to see if I can translate the panel ratings into pipe/spacing ratings. I may even run extra circuits in the walls because he plans on installing floating acoustical ceilings. The only relief I have in the designing process is that the heat gains are so small that I'm sure I will have enough surface area to get the required BTUH.

Here's my situation. The guy built his house with absolutely no room for conventional ductwork. He doesn't want to see registers, or feel or hear airflow. And he does not want high velocity. What the hell am I gonna do?

Hopefully, he has ;)

It's hard being a contractor, fighting all of the old knucklehead's "wisdom". If you don't know how to do something, bad mouth it out of existence...

Job details

@ August 23, 2012 7:09 PM in Chilled ceiling design

This is a residential home. The house is nearly air tight. The cooling basically takes care of people and appliances. I'm aware that we will need a DOAS and humidity control system, as well as condensation, dew point, and maybe window sensors.

I'm looking for the ratings for different pipe sizes at different spacings.


@ August 23, 2012 10:35 AM in Help with near boiler piping!!

Double the number 6. Pipe two tees into the header.

They have a flame spreader, which I suppose is their way of trying to create a flame retention effect. 

I hate to reply to myslef, but...

@ August 21, 2012 7:32 PM in Excess Boiler Capacity Issue

If you removed a few sections you could keep them on site for future use. Then, hopefully, you can derate the power burner, or worst case, change it out.


@ August 21, 2012 7:23 PM in Excess Boiler Capacity Issue

Short cycling is never good. You could produce excess condensation in the sections or chimney.

Maybe, if it's cost effective, you can remove some of the boiler sections.

Somebody has to ask.

Where are you located?


@ August 21, 2012 6:35 PM in convert W-M SGO to gas?

And based on your high regard for it, I'm going to be installing a few Carlin EzGas burners soon. Excited to see the difference versus Wayne.


@ August 21, 2012 3:35 PM in convert W-M SGO to gas?

We're set up to look at it tomorrow.

Chilled ceiling design

@ August 21, 2012 12:07 PM in Chilled ceiling design

I have a project that I think will be a great application for chilled ceilings. If I have to suspend tubing in the ceiling, can I design the tubing size and flow rates the same as radiant heating? Does heat transfer work both ways?

It's sad.

@ August 21, 2012 12:01 PM in Is an outdoor reset recommended

"It's no good" usually really means "I don't know".

This kind of mentality forced me to start my own business, so at least these people are a good source of motivation.

Let me think...

@ August 21, 2012 10:52 AM in Is an outdoor reset recommended


You won't be sorry. Here in NJ, resets just became mandatory.

Two cents

@ August 21, 2012 7:17 AM in convert W-M SGO to gas?

If the boiler isn't leaking, and looks like it can be cleaned up nicely, the conversion is a great choice.

I'm in central NJ. If nobody else can help you, I'd be willing to take a phone call from you. Heck...I'm not even against the idea of a little road trip.

Hot water

@ August 21, 2012 6:28 AM in Excess Boiler Capacity Issue

You can lower the hot water boiler's supply temperature to match the connected radiation's ability to overcome the heat loss. If you know the exact BTUH rating of the radiation, we can reference the supply temperature you will need. Add on a proper outdoor reset, and you could really cut a lot of that uneeded energy usage.

The steam boiler...well, maybe you can downfire it a little. Probably not enough. Is there anything in the building that could utilize a steam to hot water heat exchanger, such as the domestic hot water, maybe a swimming pool? Then you could be using that extra steam BTUH for something useful.


@ August 20, 2012 9:10 PM in underfiring a steam boiler

This statement is neither fair nor accurate.

Gas power burners in oil, wet-based, boilers work very well. There's quite a bit of history on this forum to back that up, too.


@ August 20, 2012 9:08 PM in Excess Boiler Capacity Issue

What are the exact sizes of each boiler?


@ August 19, 2012 11:25 PM in convert W-M SGO to gas?

Not sure if it's against the forum rules to talk about parts prices, but that sounds right.

Not too many people talk about Wayne burners here, but I've always used them in the past with great results. I get mid 80% efficiencies, with excess air under 30%. I personally like the fact that all of the controls are very generic and parts that I already keep in stock for all of my heating service. For me, that has a lot of unseen value. I guess it's a matter of history and comfort with the products.


@ August 19, 2012 7:53 PM in Hoffman #7&8 Equivalents?

If you installed orifice plates in the supply valves, you could meter exactly the amount of steam needed for each radiator, and would not need traps.

Do you have pictures of the traps and valves that you like the look of?


@ August 19, 2012 7:42 PM in underfiring a steam boiler

According to Utica's literature, their 140K and 90K boilers are both 3 sections and have the same water content (10.5 gallons). Dropping inbetween to 107K should be fine.

10 years is sort of the beginning of the "what if" stage. It should, realistically, have another decade of useful life, but may develop those pesky control and mechanical failures in the near future. You can get great benefits from converting the existing boiler to gas. Just be aware that you will spend a decent amount of money to do it. Add to that, the other piping repairs, and you may be close to the price of a new boiler. If it was just the conversion burner, I would lean towards yes. With all repairs...maybe...
