Under floor heating (electric)

[NozSpark]

Got to do some under floor heating in the next week or so, and have been thinking about what type of conduit to use for the sensor..

I have a KO box on the other side of the hollow block wall, about 3" off the floor and a hole made through the wall to floor level and I'd prefer to use a smooth bore conduit as it's got to come out of the back of the KO box, down the inside of the wall and then out between the heating element --- so that rules flexi is out.

Is std 20mm conduit suitable or is there something else that's better??

15mm polypipe works a treat.

Don`t forget to tape up the end that goes in the floor..........

I was thinking of getting some plastic microbore off a plumber mate!!

Should be OK??

if you can get the floor probe down microbore?? I wouldn`t have thought it`d work. An offcut of 15mm pipe`ll work perfect though - I usually use it
