Now the boiler, since it is not my first one I prefer to have a
standing pilot, reason being the pilot will provide a slight amount of
heat during summer which will keep the cast iron boiler from rusting
away. ...

That may be the case in a few cases, but, at least for water heaters
test does some years ago proved that the pilot actually increased the rust
situation. The increased temperature and the moisture from the flame
(natural gas byproducts (H²O, CO and CO²) caused additional rust.
