Hey guys hopefully I can make this clear enough to understand. I have and older house built in the 50's. Just replaced the boiler about 2 years ago and the heat just isn't that great. I have from the boiler at the rear of the house two 2" pipes running to the front of the house. One is the supply and one is the return. There are four tee's in the supply line running to each of the four radiators in the house and four tee's in the return coming from each radiator back to the boiler. Am I right saying that the system is not a loop? Shouldn't the supply run from one radiator to the next and then back to the boiler?
Can I remove all the lines in the basement and start at the boiler with 1" pex and then continue to the first radiator then to the second and so on then back to the boiler?
first pic is existing
second pic is what i want to do
