Tip :-
To get the maximum heat out of the mat, just crack the valve open slightly (not full on) so there is just a slow trickle through the mat.
This gives the water a greater chance of warming up before entering back in to the flow at the end of the mat.
If you have the valves fully open the water will pass through the mat much faster and not gain much heat. Also it will put maximum pressure on the micro pipe running around the mat which can contribute to blowing the mat.
