One pipe systems suck big time, it depends on how far away your new rad is to your existing system, if you have put it miles away don`t expect it to get very hot. A one pipe system works on the rad nearest the boiler getting nice & hot, the water then passes on & transfers to the next rad albeit cooler, it then passes to next rad & is cooler still. If you have added a rad about 20 miles from your existing setup then it might get warm by next Christmas.
