Hi
In the Summer I had underfloor heating installed under a tiled floor. Now it is being used regularly I have noticed that some of the floor area is cooler then other sections and some is even cold. I've tried contacting the plumber but have had no response (he's been paid).

Does the system need bleeding? If so any ideas how I go about doing it please?

Thanks in advance

sorry to say but it sounds like the cold spots are simply areas where no pipes were laid. Was the floor properly insulated? if it was then I would be suprised if you had any "cold" areas.

Hi deepbluearcher sorry about the delay in getting back been away. Yes the floor was installed, and the pipework was laid out in accordance with the manufactures instructions as I was present during the installation, the package came with strips of cradles in which to place the pipes. The problem seems that some of the tiles are warmer then others, could there be an air-lock?
