You have a direct cylinder heating the water directly - like a kettle. An indirect cylinder is heated by a boiler situated somewhere else - indirectly. You have two immersions.

My Mum and Dad have the same problem in the lounge. They get damp spores on the furniture though - sofa, and cupboards. The concrete floor under the lounge is lower than the concrete floor under the dining room. We once pumped out the water from the lounge but moments later it refilled as we watched...
