A little advise from the "learned the hard way" guru...
If you have a forced hot water system and leave the system set at 50 or whatever and turn off the water (prudent), be sure you have a source of water for boiler makeup. Hot water systems will need to draw water from time to time. Most people have a separate line to the boiler so they can shut off the rest of the house. I did not and over six months the pressure got low enough to munch a circ. pump. I had someone come in to check on things and I mentioned the boiler pressure but he didn't understand so did nothing about it.
Now, if you do supply water to the boiler, make sure you route the P/T valve to a sump with a pump. I had an expansion tank go (while I was home) and the P/T valve lifted when the boiler kicked on and put an inch of water in my basement in just a few minutes.
The so called experts here will say that if a system has no leaks then you shouldn't need makeup water. I operated a nuclear power plant in a previous life (absolutely tight!) and it needed periodic makeup as well.
