Re-piping the main loop of a cast-iron radiator system
I have a monoflow radiator system that heats a basement and two above-ground floors. There are a total of 14 radiators. The system gets the house nice and toasty in the winter.
The only problem I have is that the main loop in the basement is loooow. The basement ceiling is about 7' but the loop hangs down 14" from the ceiling. It is also set in about four feet from any wall. This makes finishing the basement pointless. I'm a tall guy, I need head clearance!
I want to raise the main loop up as close to the ceiling as possible and push it out towards the walls. Right now the system uses iron pipe.
I've gotten estimates from a few plumbers and they all said the same thing - they'll replace the iron pipe in the main loop with 1" copper and connect the main loop to the existing runs to the individual radiators.
After speaking to the pros this SEEMS like it would be a pretty straightforward project - simply copy the existing main loop layout. Same placement of the monoflow tees, same positioning, direction, etc. Only difference is that it will be 14" higher and closer to the walls.
Before hiring a pro I'd like to try my hand and doing some a section of this myself. I figure if I am going to be replacing it all anyway it can't hurt to try.
Are there any potential kinks that I am not considering? Is the job more complicated than it sounds? Is the risk of death higher than zero?:)
Any advice is appreciated. Thanks!
