I TOO have suffered frozen water pipes, despite having the heating on for 24 hours.

Having wooden floors, the air bricks which ventilate the area under the floorboards were letting in freezing cold air such that the pipes under the floor boards adjacent to one air brick in particular froze up, where pipes served the downstairs sink.

I managed to clear the blockage using a fan heater after removing the plinth under the cupboards.

I have since covered up the air bricks and they will remain covered through this cold weather.

I recommend this to those people who have air bricks and wooden floors. It might save them some misery and expense.
