Thanks.

@ 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.

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

YES!

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.

Disagree

@ 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.

Sure

@ 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.

Pressure

@ 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?

Boiler

@ 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...

Baseboard

@ August 19, 2012 5:20 PM in Additional BTU margin for the boiler

Correct. If your heat loss is less than the available radiation, you can heat the space with lower temperature water. That's what I do in my house. My water maxes out at 165F. When I converted my boiler from oil to gas, I went as far as calculating the BTUH loss of all of the copper pipes in my basement, and added that to my firing rate. I heat my 1,000 square foot ranch with about 30,000 BTUH.

@ August 19, 2012 5:11 PM in underfiring a steam boiler

What make and model is your boiler?

Stupid question

@ August 19, 2012 10:50 AM in Rinnai E110CP explosive ignition and low heat

Has anybody checked the incoming pressure of the propane?

Hmm

@ August 18, 2012 9:18 PM in Some fun with a definition

Rule of thumb? Gut feeling? Shrug...

The phrase gives the impression of uncertainty.

@ August 18, 2012 8:58 PM in Utica Starfire 3 steam boiler- oil burner conversion to gas burner

I tried sending you a private message. I'd be more than happy to take a look at your system.

Hmm

A heat pump without a reversing valve?

@ August 16, 2012 10:50 PM in wet return question

I would at least drop the end of the return down to the floor before rising up into the Hartford Loop/equalizer. That should be easy, because you'll need to cut those pipes anyway to remove the old boiler.

Steamhead

@ August 16, 2012 10:46 PM in Another W-M SGO question

What's your method for testing the boiler for leaks? A visual from the chimney? Signs of water vapor in the vent connection?

Request

@ August 16, 2012 11:58 AM in Contractor in CT needed

We would love to see some pictures. Then we can lead you in the right direction, if you can't find a contractor in the immediate area.

My opinion

@ August 16, 2012 11:56 AM in wet return question

I would favor a dry return over a wet return, whenever possible. I've noticed that a return like yours, with so much pitch toward the boiler, does not cause as many issues as you would think, as long as the return drops fully below the water line. It's the truly horizontal pipes that may be a concern.

You could always fix the piping after the new boiler is installed. See how it reacts, and gauge its priority.
