Re: copper oil supply line
I'd only go bigger if it's recommended by the pump manufacturer for proper sizing. Bigger can make more it harder to eliminate air, especially if it's not a gravity job.

Re: Line Chimeny or Buy New Boiler?
take comments like "I don't see much if any savings by going direct-vent." with a very large grain of salt.The OP wanted to compare the relative costs of direct-vent vs. lining the chimney. This is a question that professionals get asked all the time, and most of us do our best to make sure that ALL the costs are factored in. This includes the additional cost of a direct-vent or mod-con boiler as opposed to a chimney-vented one, the additional cost to install it and the additional and more-complicated service it will require.
This last is one of the most important factors, and it's why we prefer chimney venting. The more complicated a piece of equipment is, the greater the chance it will break down. And when it does, guess who gets the angry phone call? And the even angrier response when we have to tell the customer that the part they need is two weeks away, which happens frequently with mod-cons? We've had to do this, on equipment installed by others, and it's not fun. It's not practical to stock every part for every mod-con or direct-vent boiler out there. They're all different, and the parts for one almost never fit any of the others. But a chimney has no moving parts.
For instance, both myself and my in-laws went through this process last year and we each went different routes.From this, I conclude that you are not a heating contractor. You don't get those no-heat calls. Is this correct?
I would assume the OP posted on this board for the professional opinions available here. This is one reason the board is as good as it is. In general, professional heating contractors know what to install and how to install it so they don't get angry customers calling them when their systems break down. So it might be best to consider that.
Re: Odd Radiator Piping
No, it will remain a mystery. I was only in the house once, and briefly, so I've no other clues.

Re: Pumping Away Piping
How can I apply this air bleeding technique to a primary secondary piping set up ?

Re: Line Chimeny or Buy New Boiler?
Old retired guy here, and father of the current owner of this site. Yes to what @Jamie Hall said, and what Erin said.
And I would trust Steamhead with anything. I'd also trust Joe. Both good men. Both have strong opinions. There is more than one road. Old guys have learned that.

Re: Any pointers?
If you read, understand and follow the manufacturer's instructions, you don't have to calculate velocity.
Think about it. Manufacturers want to sell boilers. They are not going to sell boilers for any length of time if their boilers don't produce dry steam when piped properly. This is why they test their boilers to see what minimum pipe sizes will work, then include this information in their I&O manuals. All you have to do is Read The Freakin' Manual.
I'm sure you've scrutinized our install pictures, and if so, you've noticed that our steamers are all installed using the manufacturer's instructions as a minimum specification. Let's see some of your install pics.

Re: FREE Powerpile Self Generating systems class
I'd love some kind of pdf/PowerPoint self-study. Docs to keep on my phone/laptop are what I like the best.

Re: California radiant heating code needs to be fixed
The soil under my slab is like rock. It is old densely packed sea bottom that holds so little water that the water table is essentially non-existent.
The project I am doing is an addition to my existing radiant heated workshop. The project is a retrofit over an existing slab that used to be outside. There is a topping slab whose purpose is to level the existing slab, but is thick enough to allow radiant heat tubing. I have no room for insulation due to the height differential it would introduce between the existing shop and the addition, but the code does not address or make exceptions for retrofit cases.
And it really seems strange that the code requires insulation for a radiant heated slab but not for a slab without radiant heat, even though the heat loss through the slab is essentially the same. In the case of an uninsulated slab on grade without radiant heat, it just becomes part of the energy calcs, so why not allow the same for a slab with radiant heat.

Re: Oil Gauge Help
I'd say your low...about an 1/8th of a tank or 30 to 40 gallons...old tank and that low equal issues down the road...
