There is a steam boiler and several steams pipes varies from 5" to 1" hanging in basement.

Due to energy efficiency concern, the owner wants to abandon the 15 years old problematic boiler systems. Although all steams pipes are in good shape even with rusts on the pipe surface. The owner bear the historic preservation mindset and think someday these pipes might be able to reuse again with new boiler. HVAC professional came and stated all steams pipes and boiler must be removed before he can start the new installation.
The owner is trying to convince himself if that is the right thing to do. So he asked me to post this for him. Have anyone done that before without removing old pipes? It is always easy to remove but harder and cost more to install. Pleae advise. Is that a wise to keep the pipes or not at all? [img][/img]
