Hi I would like to install manifold near my boiler with is in the loft. I know it should be on the same level as all loop, but I have a huge problem with the place.. I will have 4 loop all on first floor , the biggest one 80m and 60,38,40 Boiler viessmann vitodens 50 combi, manifold + grunfos pump . 2 zone valve ( downstairs radiators ). Next year I will convert grand floor on ufh so then all house will be ufh , so this configuration need to work well for one winter. What is your opinion on manifold in the loft , will it work?? thanks
