Hi can anyone give me advice please . I have a baxi 128 combi and have 5 1m x800 k2 rads off it so is more than capable to add another . I only have 1 in the lounge and needs another. I have a 2mx800 k2 that I can fit . But my problem is the main pipes in the bungalow attic is 22mm then all radd are t off at 10mm . There is no way I can get in the attic due to very low pitch roof so it looks like the only way is to t off the existing rad in the living room and rute the pies round to the other wall so probly 10m 2 pipes. Would it work is the biggy. If not then I cannot fit another rad
