Re: Best way to handle air temperature overshoot after boiler runs heat cycle
Your self described large radiators are the reason for your overshoot of room temperature. They are still emitting heat from their thermal mass after the stat shuts the zone down. The hotter boiler water from your outdoor reset when it gets colder out is why you notice it more when its colder outside.
Re: Longest lasting steam radiator vent
I guess my reference to everything being made in China at Harbor Freight vs Made in USA struck a nerve…..

Re: Longest lasting steam radiator vent
Chinese electronics maybe, but Plumbing & Heating products?? Nah...Some ok...most horrid...many of us experienced a bad run of Gortons a few years ago, but I have had no problems before or after. I purchase & install many dozens per month and many thousands over the years. Call backs suck...I don't install any products that are troublesome. Hoffman are excellent too. Years ago, Dole & Maid of mist were very good quality too.

Re: Longest lasting steam radiator vent
On the professional level, Chinese plumbing products are a joke. They are so bad, many inspectors in these parts will turn down a fitting with "CHINA" cast into it. My institutional customers would rebid the job if I gave them Chinese materials on a job. Our USGov contracts would cancel us.
Chinese radiator vents? Ever see one crack and explode? It's on YouTube.
Chinese tools? They'll hurt you. Not one in our boxes,our trucks or our shop. Ever see the web site that illustrates the injuries from Harbor Freight exploding iron castings and saw blades?
Have I said I think Chinese castings and machining are inferior? The stuff is garbage. I and my men wouldn't wear their leather gloves; probably get a rash or hives.
Re: The Importance of Insulation in Steam Heating Systems
Couldn’t agree more. Dan is wrong on this one. For many reasons, it’s unnecessary and, frankly, foolish to remove asbestos that’s in decent shape. For protection, I encapsulated all my asbestos-covered pipe in rewettable cloth.

Re: Rectifier fuse vs. dual element or time delay
I googled "Simply Breakers" they say they have them in stock. Pricy. 24 of them are around 2k.
Probably can find them elsewhere
Re: Rectifier fuse vs. dual element or time delay
did you google that fuse number? Someone must have those on a shelf. Over night shipping if it is critical
Might check for shorts or other issues that would cause the fuse to fail?

Re: Ascent EK1T smells like raw diesel
Call them back. EK has a very good rep on here. they seem to be fairly responsive on here.
Sometimes its not the boiler that's the issue. That's just what malfunctions due to extenuating circumstances. like I suggested check the liner. You can get your cap blown off and next thing you know birds fall down there or nest on the top. i've seen it done. Do you have enough combustion air in the room. lack of combustion/dilution air will prevent drafting. Room enters into a negative zone. The longer the boiler runs the worse the condition. And there are other causes.
i'm not saying that this definitely the issue but sometimes you need to step back and think. sometimes the problem is so obvious that you cant see it.
how big is the room that the boiler is in?
Re: Ascent EK1T smells like raw diesel
The backdraft started after the adjustments the tech made on Wednesday. We can smell it. Immediate concern is CO.

Re: Ascent EK1T smells like raw diesel
check the rain cap on top of the chimney liner if your back drafting. If the products of combustion cant go up the chimney they will Back draft into the boiler room. not to mention all the other stuff that's gonna foul.
how did you determine backdraft when the tech, who have the equipment, didn't see it
