Here at UK Swimming Pools ltd we believe that although the United Kingdom does experience extremes of weather both hot and cold, swimming pools and spa’s suffer less damage if left in minor operation during the cold winter months. The fact that ‘Moving’ water has to be colder to freeze, gives room to allow the inlets of a pool and spa function during the winter time. If the pool is set to standard filter mode with the surface water skimmers and inlets working in good operation, then the surface water will ‘move’ allowing the temperature to drop lower without freezing. By keeping the water in liquid form it prevents damage occurring to the pool tile band and water run through system. You can see below some examples of frost and cold weather damage to mosaic tile bands and pool deck areas.
