Hi
Ive go a 2 bed bungalow, Im looking to put a CH system in this summer and am just wondering if i use a combi boiler system if its ok to run the main flow and return pipes up in the loft dropping down to the rads in each room or would pressure be an issue on the return pipe going back up into the loft, in which case i would need to chase all the pipe work into the concrete floors
Hope that makes sense :)
Many Thanks
