Re: Different valves?
OK… I'll ask the dumb question. What's the matter with the old one, other than it needs a good wire brushing? There isn't much that can go wrong with those things that can't be fixed in an hour or so…

if a motor doesn’t have a thermal overload a starter switch is required.
Does that motor have a thermal overload?

Re: System Sizing
Pipe the boilers in PARALLEL with primary/secondary manifolding. Piping them in series will give you all kinds of grief.
Re: System Sizing
primary secondary piping is how that is piped and how I would pipe two boilers
Do you could run either/ or, or even run both together for full output of 300k
Primary loop would be 1-1/2”
Boiler piping 1-1/4, manifolds 1-1/4”

Re: buying a hydronics business
For the large amount I would want to see his client list, and financials showing what he has paid himself.
Do you get the company name and phone number?
How many hours a week does he work for that salary?
Tools, truck, inventory?
40 hours a week, 50 weeks a year= 2000 hours
So you need to add at least $50.00 and hour to your labor rates just to pay him
If all three if you want 100k a year, $150 per hour per billiable hour just for salary.
Its doubtful you will have that many billable m, productive hours a year, so maybe pushing 200 per hour
Here is a really good deal 😁 to maybe help with some number crunching

Re: How much does size matter?
it is 97,000 output, but that is in a lab test. how close it comes to that will depend on how cool you can run the ci radiators and get the design output. if the house is 2 story that calculator is way off because it will be guessing about 2x the roof area you actually have.

Re: Will I have to drain my whole heating system?
if it is the relief valve there should not be a valve between it and the boiler.

Re: buying a hydronics business
I would assume for half a million dollars you are also getting 4 eager employees ready to work for you, all with vans and tools right???? If this is an owner operator business just respectfully decline, most of those business are barely worth $100k to anyone other than the owner operator and he wants 5x that amount.
If you have the licenses just start doing business yourself and his customers will still call you when he retires…. If you don't have the licenses well that would be step 1, 23 is awfully young to have a master plumber license, that would be the youngest I ever heard of personally so I would be amazed if you had a master plumbing license, and your boiler installer and unlimited service license at that age.

Re: Thin Tube Steam/Hot water in Barre VT
I have a home built in the late 1800's. Fieldstone foundation and a high water table. When I first moved in we'd get multiple leaks into the basement whenever it rained heavy. The previous homeowners poured a slab over the dirt floor and sloped it to drain to one corner of the basement.
There were no gutters and all of the water from the roof drained right next to the foundation and easily made its way inside. Over the years the soil eroded away and created a negative slope towards the foundation, making the problem even worse.
I fixed the soil grading issue and installed gutters making sure the downspout outlet was about 6ft from the house and draining away from the house.
Big improvement. The only time we ever get a hint of water down there is during extended torrential rainfall when the rain is going sideways and running down one side of the house. Even then it is barely a small puddle.
You can't waterproof a fieldstone foundation. The lime mortar needs to breath and moves with the earth. It will deteriorate rapidly if it is sealed over.
I'd avoid putting heavy plastic down on the dirt floor until the water issue is resolved. You will be sealing in the mud, muck and organic materials and it will get nasty under there.
Solve the water problem first. Make sure all rainfall finds its way as far from the foundation as possible and improve the grading to naturally drain runoff away from the house.
And make sure you don't have any sewer flowing back through the soil. I think one of those "Drain Cleaning" companies can do an inspection for you and locate any potential blockages or cracks. Many repairs can be made without digging up the sewer line.
Re: How much does size matter?
that calculator gives me a load of 103,554 BTU/hr. My boiler is an 85k mod/con and when I checked up on it this past winter when it was -15f outside it satisfied a call for heat in less than 10 minutes. That calculator is pretty far off, that being said a 125k with a 10:1 turndown is going to be fine, I just don't think your actual load is anywhere near what SH suggests.
