I have my boiler outside my home and the system is filled with antifreeze. I only add water when I service the system once per year and I do not have a direct connection to the water system; I fill the system with a temporary hose. I do not want to have city water push my antifreeze out of the system through a leak I did not discover because I had the system automatically filled AGAINST the pressure reducing valve manufacturer's instructions.

So the answer is:
Yes. Install the low water cutoff control in the system and close the feed water valve to the LEAK-FREE and SEALED hot water heating system. The deoxygenated water will not harm the metal in the system as can fresh water running through a constant leak and the boiler will last indefinitely, if not FOREVER, which is more than your lifetime.

I live in Northwest NJ and have an oil-heated boiler that heats both drinking water and also provides hot water baseboard heat.
I have heard of horror stories of people going away on vacation and pipes bursting, etc. So, when we go away on vacation in the summer, we open up all the taps, shut off the main water to the house and turn off the boiler.
In the winter, for obvious reasons, we cannot shut off the boiler and the heat.
Thank you in advance, symboltech
The proper control to protect the boiler is a Low Water Cutoff. If one is not installed, install one and rely on that to save the boiler from the damage of running out of the less than ten gallons of water in the system. here

A new energy-efficient boiler could save you hundreds off your heating bill every year.
If you have an electric shower — and don't take baths during the summer — and a dishwasher, only water used at the kitchen sink and in a bathroom hand-basin would need to be heated. more
Read on to find out if turning off your boiler for the summer is a good idea.
Tankless water heaters last much longer than tank-type heaters and produce an unlimited supply of hot water, but are much more expensive to purchase, install, and repair. more
The water that enters your home through the main water line is pressurized, which allows it to travel against gravity through your pipes. This means that water can flow very quickly, whether from a faucet, hose or through a broken pipe in the case of an accident. If you do have a broken pipe, it’s important to use your emergency shutoff valve to avoid heavy flooding. here
In other cases, turning off your water heater may be desirable, but not necessary, like in the case of a leak . Leaks can happen for a number of different reasons:
The water that enters your home through a water line and the connected pipes is usually cold or cool, even in the summertime. For you to have warm water in the home, the water needs to be heated after it’s delivered through the pipes.
