Re: London Apartment Outdoor Waste-Line?
I imagine running pipes concealed in a 600 year old 2' thick stone wall might run towards the spendy side of affordable.
Re: Mandatory "Stay at Home" orders
Good steam work is still essential, though Knuckleheads are considered non-essential until further notice.
Tools and Tables for easily determining the Steam Velocity in boiler risers.
Hi All,
The discussion in 1 or 2 risers (@scott_block's recent thread) sparked my interest in this; I suddenly wanted to compare the velocity of the steam in the risers of the various configurations being suggested, along with that of other boilers cited in this thought-provoking discussion.
I found (as @The Steam Whisperer pointed out) the formulas for calculating Steam Velocity in my copy of @DanHolohan's The Lost Art of Steam Heating Revisited. Being mathematically challenged (I'm fully capable adding the same column of figures five times on a calculator, and getting five different results), whenever I have an algebra problem I build a quick-and-dirty tool on an Excel spreadsheet and let the computer do the math for me. This I did, and after working with this tool for a bit realized that it could be of value to others in the HeatingHelp community.
So I prettied-up the spreadsheets, added tabs with a Specific Volume look-up, and a tool to calculate Gross Output in lbs/hour from other types of gross and net boiler outputs. The result is the attached Excel workbook (Steam velocity.xlsx). Anyone who has Excel, or any other program that can open and run Excel workbooks is encouraged to download and try it; comments and suggestions are most welcome. For those who lack the software or inclination deal with an Excel workbook, I've also attached three tables, in .pdf format which can be viewed and printed using Adobe Reader. Here's what one of those tables look like:
And here's are examples of using the tables:
I plan to add more tables and such, as I have time, and upload them here. This will likely include tables with the data for popular residential-size boilers already filled in. This is a small way of giving back to the HeatingHelp community.
Please let me know what you think.

Re: ***Installation Disaster*** homeowner needs advice
They could have looked at the installation instructions.
Make sure the next guy installs isolation valves and unions at each piece of equipment, insulates his pipes, wipes the flux off any soldered fittings and reads and understands the installation instructions.

Re: That would be nice
I've seen that point made in quite a few Dead Men's Books. Everything old is new again.
Re: Sharkbite for Refrigeration Lines?
I haven't seen a flare connection on a cond unit or coil in the last 30 years.Have you done any mini splits?
Re: What phrase do you associate with your dad?
Other things Dad said that stuck
"Never say you Hate anything, you can dislike many things, but hate is such an ugly word"
"Kids are young goats, young humans are Children"
"I really do not care what career path you choose, but whatever you choose aim to be the best you can be, whether you are a Doctor or a Dishwasher"
"if you would drink one less six pack a week, soon you would have money for all the tools you would need"

Re: What phrase do you associate with your dad?
My father would also say, "Never expect anything from anybody. You'll never be disappointed."
If I was sick and complaining, he would say, "Look kid, two things can happen here. Either you'll get better or you'll die. If you get better, that's good for you. If you die I gotta bury you and that's my problem. So how about you just shut up."
And then, of course, there was, "Wanna see a match burn twice?"
He was a pipe smoker. I have the scars on my forearms to prove it.
I miss that guy.

Re: Plumber says `Normal Corrosion` - Lochinvar Radiant Heat KBN080
I agree that the leaks in and of themselves are fairly normal. The threads may of may not have sealed themselves over time. There may still be an intermittent leak. You are likely not looking at corrosion but just calcium and mineral deposits leftover from the leak. It is puzzling that the someone came to look at the boiler corrosion but did not bother to clean it up and reseal the threads.
My concern on this is not the corrosion damage effecting performance. My concern is that this boiler has likely never been serviced at all. There should be an annual maintenance schedule in the owner manual. This maintenance should have included not only fixing leaks like these, but should also include opening the boiler, cleaning the heat exchanger and performing a combustion analysis.
Imagine going to purchase a used car with 100,000 miles. Would you be concerned with oil stains around the transmission seals? What if the same car with the oil stains had no service records? No evidence of 30K, 60k 90k service or even an oil change?
Lochinvar is a solid boiler. This boiler probably just needs a thorough cleaning (inside and out) and combustion analysis. I would be surprised if the condition of this boiler turns out to be a deal killer on a home sale.
Just like a used car example, download the manual, ask for the service records and negotiate the price based on the service history.

Re: AMERICAN MADE
I'd be surprised if everything in a "American Made" boiler was made in the USA. PCBs from Germany fan motors from Slovenia relays from mexico resistors and switches from China. At least that's what I've found to be the case.
