Moving A Boiler

Doug_2

How far can one move a boiler from its current position on the heating grid? We'd like to relocate the boiler to one of 2 postions: the first is only about 5 feet from its current location at about the halfway point under tha main pipes on the grid, the other would require a good 25 foot run to reach this same position (although we might be able to shorten the distance to about 15 feet if we were to tap into a new place on the main grid. We have hot water radiators. We would like to use the existing grid to avoid repiping to each radiator in the home.

With a hot water boiler

Relocating it shouldnt be a problem . The main concern is how far away would the connection to the chimney be ? There is a certain maximum distance you can run a flue pipe , and it needs a certain minimum pitch .

If youre connecting to a monoflow system , you have to make sure there are no air traps in your piping , or you can try to purge out the air in the main pipes , bleed the radiators and hope for the best . Good luck .

Thanks for your reply. The boiler is being repositioned (in either case) next to an exterior wall for side venting. We have been side venting the boiler from its original location to the sidewall right next to the proposed 5-foot relocation for 4 years now with great success using a Field PVO power venter.

In our system, there are main and branch lines suppling each radiator with hot water and a separate set of branch and main lines returning from each radiator to the boiler.
