I should add to my prior post, just briefly. Those steam / return pipes (to and from the boiler) must be correctly sized and pitched as well. The near boiler piping needs to be BIG. If you're replacing a boiler, follow the boiler manufacturers directions for the near boiler piping very closely. And make certain the steam lines in the basement are insulated – it makes a huge difference to efficacy and speed of heat delivery to the right places.
Good point and also use copper pipes in place of the cheaper common black pipe that actually rusts inside and ends up like a heart attack victims clogged arteries.
If you have 'old black pipes' as your leads to and from boiler that date back to way back when - it's worth replacing them with copper for much improved heating efficiency.#Winter
