Floor Probes for Heated Slab

[Spinny]

I have a concrete slab approx 120mm thick with heating pipes embedded in the middle. Controlled using Heatmiser and a wireless thermostat.

 

I will be having levelling compound and LVT laid in a few weeks and am therefore contemplating getting a temperature probe into the top of the concrete slab to provide a continuous monitor of the floor temperature. As I understand it the floor temperature shouldn't rise above 27C for an LVT floor. (Up until now I have just used a temperature gun occaisonally to check the concrete surface temperature).

 

I currently have a floor probe from Fast Warm which terminates in two wires, and a Sonoff zigbee temperature probe which terminates in the zigbee device and small screen.

I also have some small diameter flexible conduit, and some spare u/floor heating pipe from my suspended floor.

(See pic)

I plan to cut or hand chisel (will this work?) a recess into the top of the concrete slab, lay the conduit or pipe in the recess, and chisel it into the plaster to run it up the wall into a cupboard (See pic). Cover the recess/pipe with Ardex 45 and the levelling compound when laid.

 

Any advice please ? Should I use the flexible conduit (more easily bent through 90 to run up the wall but much less robust than the pipe) or the pipe. If the pipe, how can I straighten it and bend it through 90 at the wall ? How important is it to have the temperature probe ? Might the floor crack or move if any heavy furniture is placed on top of the pipe location ?

I just wouldn't bother, more tatt sold to people. You going to need high flow temps for a long time to get to 27 degs.

 

What is your heat source and how is it plumbed in to the UFH?

 

Is this a new build or retrofit?
