Re: How bad is it going to be to repair this leak?
Might want to consider opening the ceiling below for access.
When my customers gripe about cutting access holes, I tell them I can cut it now with a saw and vacuum, or the firefighter can cut it later with an axe.

Re: Move Sunrad from inside wall to wall surface
if the house needs siding in long term trajectory, i would leave the radiators recessed and put an inch and half of foam over the sheathing on the outside and then reside. you have to work out molding details but i'm doing pretty well on a house that has 3 layers of siding on it already. that gives me space for the foam and siding without coming way proud of the molding.
@ethicalpaul still glad to blow up 570 for research porpoises although that probably violates the marine mammal protection act

Re: Does gas need to be turned off on furnace
Gas appliances that have been manufactured after 1950 have safety systems built in that pretty much prevent them from letting out any gas when they fail or are turned off. It is called Fail Safe Designing and is built into the equipment. It is kind of idiot proof. Of course that is based on the typical 1950 idiot. From what I have heard from many manufacturer's reps is that in the past several decades, we have been producing a better class of idiots. So maybe you should turn off that gas valve.
Re: Does gas need to be turned off on furnace
Put a bucket under the drip leg. That should be fine until the repair is done.Therfamily123 said:That’s been done. We just wanted to make sure there was no risk to gas still running/leaking

Re: Anyone ever seen this style steam rad?

Steam boilers in homes are for the most part an 80% to 85% AFUE fossil fuel appliances. Electric steam boilers are 100% efficient. However, that does not take into account that the delivery system is much more efficient. The amount of energy stored in just one pound of water (that is slightly over one pint) when it is converted to steam is over 950 BTU. That is called Latent Heat. Explained simply: to convert one pound of 212°F water at sea level into 100% steam at 212°F takes 970 BTU of energy. That is where the efficiency of steam happens. That is because it is so easy to move that steam from the source to the emitter without any other mechanical devices. Just a small pressure difference at one end of a pipe will move all that heat to the destination very efficiently. In some cases only a few ounces of pressure are all that is needed.
Add to your argument that radiators can be heated by water. And there are some devices that heat water with amazing efficiencies exceeding to 97% AFUE in some cases. Your blatant disregard for a heating emitter that has both function and beauty is by some standards satanic. But being his advocate, you may take that as a complement.

Re: Problem with short-cycling, low water, and leaks
I'd be sure it is surging before going down the road of re-plumbing. You should see the water level in the gauge glass drop dramatically if it is surging.
There is enough strange information in this thread that I'm not sure of anything right now.

Re: Dope & tape?
You have to love how these tape/dope discussions go on for days. Like i said in my first post 30 poster, 30 answers. We are up to about 20 now.
Re: is a power draft-assisted burner considered a "appliance with a draft control device"?
Remember Thermizers from the 80's? They were sold as Draft Control Devices. I suppose shrinking the opening in the vent pipe, which is what they did, does qualify. Free CO meter with each purchase?

Re: 38 year old boiler - is it the cause of high gas bills?
I agree completely with the $200/month being very reasonable. The Dunkirk is a fairly efficient design. I doubt a new boiler, with repairs, parts and maintenance will see much of a savings.
There are folks here in New York in new houses with "modern, clean electric heat" paying six times your bill each month.
