Hi guys, I,ve got 13 rads, and a new Veissman boiler, however, 1 rad, which is the last one on the circs, in the lounge,( 2 others in lounge) only gets warm, whilst the others are hot.The system was flushed , 2 years ago, when boiler installed, I,ve taken thermostat off rad, the inlet pipe is hot to the valve, but not the rad, or, where the valve goes in the rad. Been like this for years.Bled it, even temp all over, just won,t get as hot as othersI,ve tried turning all rads off, leaving this one on, it does get hot then, but when all rads are on, it,s only warm??. Any advice welcome.
