Hello to all, Im Gary from Chicago, just looking for some help with my radiator issue. I have a hot water boiler with 3 zones and a pump for each zone and a Taco switching relay. 1 zone goes to my 1 story addition on the back of the house with a crawl space underneath.
To make a long story short, I replaced the cast iron baseboard radiators that were in that room and added 2 walls of slant fin copper radiators (approximately 20' total). The problem is when the temp drops below 25f outside, the thermostat in this backroom won't go above 65f. We do have a little electric oil radiator that we plug in and that gives off enough added btus to allow the thermostat to reach whatever desired temp.
I have 10' of extra radiators I am getting ready to install in that room on another wall. My main question is how would you guys run the piping. Currently I have it in what I understand is a 2 pipe direct system. I eliminated all the old galvanized piping that was in the crawlspace and changed it to 3/4" copper.
I am wondering if I should keep the piping the same way when I add this extra 10' or run it in a series loop. The extra 10' of radiator will bring me to about 30' total. The crawlspace is not below grade and is only insulated with very thin fiberglass insulation between the floor joists. I did insulate all the copper with 1" fiberglass( 1" or 1/2", cant remember).
Here is a diagram of the piping that I currently have.
