Oh Yeah! When cutting ferrous metal, carbide tipped blades are your friend!

Re: The last word about c-wire thermostats and wiring diagrams.
Common is confusing too. In this case common is the unswitched side of the power source that is connected directly to the load but if you just said common to me with no knowledge of hvac I would think of it as the switched side of the power source.When you hear "common" in electrical, you think of a switched wire?
I think of neutral.

Re: Understanding heat flows in high mass heating systems in old houses
We have an 1855 farmhouse in MI that we renovated using all of the existing cast iron radiators and got some more to boot, plus some panel radiators and heated towel racks. It is a high mass system of 16 or 17 radiators. We are using a Viessmann 222F mod-con boiler. No thermostats in the house. I also made a point to use 5/8 sheetrock throughout the house and it has a two-coat plaster finish. High mass. Works great.

Re: Hydrolevel VXT
Mad Dog_2 said:I built my Steam Vapor System from scratch starting in 2001. One 1/2" Apollo Ball Valve. No water feeder. I understand in a commercial situation, but the whole reason for a VXT is to track feed water usage, right? Find and fix the leaks and you can go with several Mc Donnell Miller Models that are very trouble free. I don't know why MM doesn't have a metering model to compete with the VXT?. Mad Dog 🐕

Re: Removal of 80 gallon stone lined water heater
I love it! Reminds me of the man that taught me most of what I know mechanically. He just turned 80 and is still working. A year ago I was working on a shutdown he was running at a mill and had finished the first job he had given me. I went looking for him - found him changing a 6” steam seperator by himself with a couple chain falls. Had the old one down and the new one rigged and ready to lift.

Removal of 80 gallon stone lined water heater
Back in May I decided to finally replace our 80 gallon stone lined Vaughn electric water heater. It was over 20 years old but not leaking and may have lasted forever but it's an energy pig for two people. These Vaughn stone lined tank were very popular with the electric utilities installed them (including this one before we owned this place) for years. But our local utility gave up on that a few years back and said "you now own the tank."
Thanks a lot!!!
I knew it was going to be a PITA and wanted to get it done before it let go or I got any older. It probably would outlast me!
So, I bought a new 40 gallon and installed it back in May. The old heater with the cement lining is about 400# empty. I got it up on some 1" pipe for rollers and pushed it to the side where it sat and sat LOL
I stripped the plastic jacket off it and then all the 2" foam. Originally, I thought I would cut it with a grinder with a cutting disk and then break up the concrete. The stairs are very tight with a sharp turn at the top and bottom. No outside entrance to the cellar.
The cellar is semi-finished off so I hung plastic around the tank area and with safety goggles and a mask started cutting. It just made too much of a mess and the neighbors (we are in a condo) complained about the noise. I folded back part of the steel (1/8" thick) and tried busting the concrete and that was going to be tough. I also tried a Sawzall and bought a metal cutting blade for my Skill saw and that didn't work out well either
So, then I tried call a few junk guys to take it out. No one wanted anything to do with it. The one honest guy told me to cut it up he would have to charge me over $xxxx.xx to take it out.
Time for plan B
So today (while my girlfriend was gone for the day) was my time to strike.
I used a Come a Long and pulled it up the stairs which worked like a dream. Once I was all set up I had it upstairs in 10-15 min.
I used a 5/8" eye bolt with a rod coupling and a piece of rod with some nuts and washers a made a hole in the sheet rock wall.
Now you know why I waited till she was gone.
I put a 3' 2 x 6 on each side of the wall to sandwich the wall. No damage to the sheet rock at all except for the 1" hole I made which I patched.
So, the good news is I got it out of the celler!!
Bad news is it's sitting in the kitchen so I am still feeling the heat.
I got to wait to get my brother to give me a hand getting it out the door down 3 steps and onto my trailer.
But I let my Neice borrow the trailer and when I texted her today, she said it is sitting in her yard full of mulch and has a flat tire.
When I stretched out my come a long it was 3" short. So, I had a few xtra shackles I made up the distance with. Of course when I got up to the top step I ran out of cable and had to disconnect the shackles. I drilled a hole in the tank and used a piece of 1/4" wire rope and some clips up and back up through the HW outlet to hook on to the tank.
So the saga continues!!

custom feet for our old wall-hung rads
made a 3d reproduction model of these bolt-on feet and had them machined out of aluminum. All will be powder coated a nice metallic bronze

Re: What is the highest efficiency residential boiler?
Ironman is giving solid advice... you can often cut fuel consumption 20 to 30% just by making sure the system is working optimally...i,e. installing and properly setting up the thermostat for steam can cut fuel usage about 12% if the current thermostat is not set up properly. For a boiler replacement, you may want to first make sure the new boiler is properly sized. You may want to look at small power burner boilers ( ie. Peerless EC) These should give you even better efficiency. This type of boiler is used in large commercial applications, but can be had in a small size. The EC heat exchanger is designed for use both for gas and oil firing, while most small power burner boilers are designed mainly for oil firing.
Also, another thing to remember is that the simple atmospheric boiler uses about 1/80th ( not 1/8th) the electricity of a "high efficiency" forced air furnace and somewhere around a quarter of a "high efficiency" hot water boiler. The efficiency numbers on equipment are extremely misleading when comparing different types of equipment as they are not based upon the total energy consumption of the equipment and the losses in a typical system.
