Thermostatic Radiator Valves are an option.

Re: New Propane Boiler Options
there is an uninsulated hole up the middle of the tank (or sometimes routed differently in oil water heaters), that is going to significantly increase standby losses.

Re: Question about lining 90 year old cast iron sewer pipe
Cast iron and clay can be lined. It depends on the company doing the job and what product they use.
A reputable company will do a full accessment of your system and offer their advice. They should send a camera down the piping to determine how feasible it is to do the job.
I would also get a plumbers perspective on how to correct your issue. You might be surprised as to how plumbing can be re-routed, pumped and plumbed for a drainage upgrade. The cost can be less in some sercomstances, and be a better more reliable job.
Companies vary from how they do things. You will need to find a company(s) in your area.

Re: New steam boiler - newbie help
You can and in my opinion should total up the radiator sqft edr in you home yourself particularly if the contractor did not share the radiator by radiator details with you. It is not hard and then you know for sure whether you are getting the right size boiler. Below is one of many cheat sheets to use. Send photos of your radiators to this forum if you have any questions or doubts about the measures.
Re: What size liner?
NFPA 54 has the specifications. Don't take it upon yourself to do the job of the professional. The size of a chimney liner required by NFPA 54 depends on several factors, including the type of appliance being vented, the fuel type, and the specific venting system used. You know the size because you have selected the WM CGa4. but before you actually select that boiler, are you sure that it is not oversized for your needs?
Assuming that the proper heat loss calculation has been done and you know that your home has a heat loss of more than 52,000BTUh and less then 77,000 BTUh then the CGa4 is the proper size boiler for your home. Chances are, if you are replacing an existing boiler with the same size boiler, then the CGa-4 may be oversized.
The gas input of the CGa-4 is 105,000 BTUh so the gas piping and the venting must use that specification to select the proper size. Here is an excerpt from NFPA 54 published my MetalFab. These Venting tables indicate that if you are venting a single category I appliance that is rated at 105,000 BTU input when using a single wall vent connector (the connector is commonly called the "smoke pipe" that connects the draft hood to the chimney base) you must have a minimum diameter of 5" diameter based on table 6, and should not be larger than 12" diameter. There is some disagreement as the the maximum size number and I refer that issue to @Bob Harper, the Venting Expert on HeatingHelp.com.
However, I believe that Maximum size is not the issue for you. You just want to know the minimum size in order to select the proper liner size and 5" will do it. Now sliding a 5" corrugated liner into that chimney will actually reduce the free area to something like that of a 4.5" diameter smooth pipe. So I might opt for a 5.5" corrugated liner. Or you can line the chimney with 5" smooth pipe sections and hope you don't get stuck half way thru the project. 6" will also do it if you can fit it down your chimney. The larger one will allow you to add another gas appliance in the event that you want to add a water heater to that chimney in the future.
I hope this helps.
Still believe that you should leave it to the experts
