Hello replaced my boiler to a valiant ecotec plus 832 before i changed my boiler i only had 1 out of the 2 radiators on and never needed the ones upstairs on cause it was always warm enough.... Now i have to have all the radiators in the house on...all radiators are on full and boiler is on hottest settings.... All radiators are all red hot but when you put your hand over the top you can't feel any heat pumping out.... Does anyone know what this could be.... Thank you...

hi

have you bled the rads?

best to always have flow through all rads even if your warm enough as it prevents sludging the system.
if you want to be frugal then turn boiler out put down to 50degrees or so.
