We havec recently changed our boiler from a conventional boiler to a condenser combi, feeding 7 radiators.The problem we are having is that the the rads are hot at the top but cool at the bottom. We have thermostatic valves on the rads and they sare all turned up full. Can anyone suggested how i can solve this problem. Do i need thermostatic valves on all the rads or can i change them
