My daughter has just had a new boiler, her system is radiators to upper floors and underfloor to all of ground floor. Despite the valve serving the underfloor being turned up to a high temperature and the pipe leading to the pump being very hot the flow and return pipes on the manifold are only luke warm. The valve is on 60 or 65 but the temperature on the dial after the pump is only 30 degrees. I enclose a photo with the flow and return marked in yellow and the hot pipe leading to the pump marked in blue. The pump sounds as if it is working ok. In addition I can’t see how the flow on each circuit can be adjusted as the flow indicators do not look like they can be adjusted but there has to be a way.
Any advice would be much appreciated
