Re: System 2000, nearly double the cost of Weil McLain, is it worth it?

Using 1/3 less oil sounds pretty extreme. Is that actually realistic?
I'm not a heating pro, but I am a mechanical engineer who has done a fair amount of number-crunching on boiler efficiency in general, and in particular on the two Weil McLain boilers heating our 4-unit condo building near Boston. And IMO the answer is no, expecting a 33% reduction in oil use from an EK without DHW is not realistic in your situation. If your boiler is cold start like ours, it's probably running at around 70-75% overall efficiency, including combustion and latent heat of vapor losses. A non-condensing EK boiler might get you up to 80% overall efficiency, so let's give it the benefit of the doubt and say you'd get 10% better efficiency. You are absolutely not going to get 33% improvement, and IMO you're not even going to get 17% improvement.
So don't believe whoever is blowing sunshine up your butt. EK's are great boilers and can save big $$ in certain situations, but yours is not one of them.
And by the way, our two Weil McLains are 30+ years old, still in good condition, and we let them sit idle all summer.
I live in NY State in an old drafty house…
If I were you, I'd start there. Even if you do install an expensive EK boiler, you'll still have a drafty old house. I would buy the Weil McLain and spend the money you saved on air sealing the house first. For example, having the old windows professionally weatherstripped with spring bronze seals along the sash sides and silicone rubber bulb seals at sash tops, bottoms, and parting rails. Or consider replacement windows. Then insulation in attic and walls.
Your real problem is that your house is leaking heat like a sieve. Once you fix that, even the Weil McLain will run less often and save you money.

EKs are good but
"It will make up the cost difference in savings in 2 years"
I doubt that.
Re: Options for increasing gas pressure without using local gas company
Has anyone actually measured the gas pressure? What were the results of their measurements?
If no one has measured the pressure, they're all assuming. There could be several other reasons why the water heater is underperforming.

Re: System 2000, nearly double the cost of Weil McLain, is it worth it?
HVACNUT is on the money. A replacement W.M. is cut and slide, nothing gained but cheaper. We have installed EKs for 15 years, big savings for customers. I love 'em.
Re: Replumbing: Solder or Threads for Ball Valves
Maybe, maybe not, if we're talking water quality. Yeah ,Chicago may be exceptional, but it's not the only place where copper would have a century+ lifespan.
Re: Experience I had with a boiler tech and what I learned along the way.
"many technicians haven't read since high school"
Are you sure about that??
From the installs we see on this forum I don't think they can read at all LOL
Re: Monoflow Tee vs Diverter Tee
No. Monoflow will not work with gravity.
There was an old fitting similar to a Monoflow that was used on gravity (OS fitting I think) but those installed at the radiation.
Monoflow fittings have too much resistance for gravity.
Re: Peerless
There's no need to be so aggro, and yes your point is now clearer.
I see both the old 63 and 64 lines on their website, in addition to this new 63-x model. I'm not familiar enough with the Steam Max to be able to say myself that's what it is, but I don't doubt you.
They could might have chosen to license it to rebrand it so they could have a higher-efficiency steam model? Scratch that, the efficiency is only 82.0%
It would be cool if there were a press release announcement, but they are a strange company in some ways, even though they make my favorite steam boiler. The internet is completely silent regarding the Peerless 63-x
Re: Steam pressure question
@geemalar Use a brass pigtail …not steel and all brass fittings. Put the low-pressure gauge on. Also replace your 0-30 gauge as well.
If it was me I would put a 1/4" ball valve or petcock under the new lo pressure gauge and keep it shut off unless your checking the pressure….it will last longer.
And don't worry about the lack of pressure. The lower it is the better. As long as the house heats and is quiet that is 90% of the battle.
Re: Packing Heat
@DCContrarian You are wasting your breath. Once somebody drinks the free solar energy coolaid, no amount of science will get them back.
We both know that, except for pool heating, solar thermal is dead. If it would be cost effective, people would use it. Never mind the maintaince cost of all the plumbing down the road.
