I am trrying to determine what type of heating system I have. I only have 1 water tank in the loft. My water storage cylinder appears to have a coil in it which is fed from the boiler and heats the hot water supplied to the taps. From this I would think it is an indirect system but I cannot find a second tank for topping ou the heating circuit. Any help would be appreciated.

Thanks
