Unions on boiler system

[Kamil]

Hello everybody,

I am repiping old heating system into loops with the boiler remaining the same at this time but it will be changed in the future. I want to use unions to facilitate future boiler replacement. Is there any problem using unions on boiler system. I was wandering if they cause leaks due to constant cycles of heating and cooling.

Thank you very much for tour feedback. Happy 4th of July!

If your piping skills aren't great they can leak, but generally they are fine.
