Hi
need a bit of advice, i have just renovated a house and had a brand new system installed, ground floor is 7 port, 3 zone underfloor heating (pipes in screed) and first floor radiators, Boiler is a Ferroli Optimax 30, and tank is unvented Santon 210, first floor, ground floor heating and water are seperated by a 3 channel programmer, on a very cold day when i run the ground floor underfloor heating and i run the upstairs radiators, the radiators take a very long time to warm up, actually its almost impossible to get any heat out of them, the underfloor heating has its own pump and mixer, i was thinking whether the first floor needs a additional pump or do i need to change the ferroli for a powerful Keston C40 or vaillant 637 , when i switch the underfloor off then whitin a couple of minutes the radiators are piping hot... any advice please
