Oil furnace issue

don't use it unless you are sure the boiler is full of water, it could cause a fire

the pressure should be at least about 10 psi and it is at 0. you need to use that valve to fill it but wait until the gauge reads around room temp before doing it. it reads about 180 now. it likely will come pouring out the broken radiator before it builds pressure.

you could lift the relief valve and add water until it comes out there.

watch that you are not flooding something upstairs as you fill it.

the tankless coil for the domestic hot water sits in the hot water in the boiler. the boiler needs to be full of water for it to make dhw. the boiler is also designed t obe full of water when it is heated. it could crack if it isn't completely full.

your problems aren't with the boiler, they are with the system.

as a side note, in most areas oil is far less expensive than electricity. also keeping the boiler hot al the time to make dhw uses a fair bit of fuel, it is less efficient than a gas or oil or electric water heater if you aren't also using it for heating.

Me ,wrong low pressure …

@cooljazz1976 , where are you located? We might know someone who can help.

@cooljazz1976 , how about posting a pic of the bad radiator and the piping connections?

It wouldn't take much work to disconnect and cap those pipes on either end of the radiator. Any competent plumber could do it.

Yes, in fact that's the best way to do it because at some point someone will probably want to put another radiator back there. New cast-iron radiators are expensive, but used ones are generally available.

I live close to you, there are some good plumbers in the area i can recommend to you. I just scrapped a 1975 efm a lot like that because the base was bad. If you only use it for hot water I would suggest putting in a hot water heater instead of putting money toward the repair of a system you're using for it's secondary function anyway.

My brother is retired now but he lives in Richboro PA in Bucks County.  This is the company he built F T YOUNG Associates 24/7 Emergency Service Available Call 215.357.4300. Not sure if the new owner goes to your location but it would not hurt to ask.

I think there is a contributor in your area that goes by @STEVEusaPA . I don't know for sure if he is even still working but he knows his stuff. 

In Schuylkill County Pa I can’t believe that Electric Heat is less expensive that oil heat.  And if the boiler can hold water to make hot water, you can certainly heat your home with it after the bad radiator is removed, repaired, or replaced.

Oil is purchased at one time before you actually use the energy. Gas and electric is paid for after you use the energy. As a result of this difference, comparing the price you pay in one month of a utility bill with other usages like the refrigerator and lighting can't be equally compared as easily. You may also be heating the entire home with your oil heater and only heating a few rooms with electric, so the comparison is again flawed. (not heating rooms that have radiators may cause a radiator to freeze and crack)

You can reduce the amount of heat going to unused rooms by closing the radiator valve and get a similar reduces usage. Think of heating only three rooms with electric and then adding all your other rooms with electric heaters. That same $300 spike would turn into $700.00 real fast, but the reduce oil heat with radiators turned off might drop to only 75 Gallons extra in a winter month. That oil boiler with the proper tune up will also burn less fuel.

Have you thought of financing new equipment? The lower cost of operation will help in making the monthly payment on the new equipment. Just some thoughts from a guy with 40+ years in the trade. And I'm still learning.
