i have been told to buy a indirect pumped hot water cylinder. but when looking on the net and in the screwfix cataloge i do not see any refurence to pumped on non pumped cylinders. .i can find indirect cylinders but they do not say whether they are pumped or not.can any one help me with this. many thanks.
peter8899,
Indirect cylinders have a coil in them which is heated by the primary circuit, this can be either pumped or gravity fed. If pumped the pump is located in the circuit to the heating coil.
