    Low hot water pressure in entire house (Heatslave External 25/32)

    We have low hot water pressure in the entire house. Boiler is a Heatslave External 25/32, fuel in kerosene. The central heating is still working. Water initially heats up but soon flow ceases. The gauge pressure is correct. Do I need to release air or residue somewhere? Thank you.
