Timed switch for electric underfloor heating

Have a look at these time lag switches:

The vacuum ones are quite popular and you can buy a splashproof shroud for it.

Most of them only go up to 10mins but the EK 560A-1 can be set up to 2 hours.

 

Pretty much a pointless idea, I come across this alot with customers, underfloor heating is not something you can just switch in and off, I've worked on bathrooms and kitchens that can take a couple of hours to start producing heat

Heating programmer's are the best ting for the job, just try to explain the concept to the customer

My mothers underfloor heating is now switched off it was a total failure. Main reason is it takes so long to warm up. Fitted in a wet room switched on and nice and toasty the shower is used which cools it down and it take 20 minutes to rewarm up before starting to dry the floor.

But there is also a second problem with underfloor heating there are two thermostats one in the tiles and one measuring room temperature they are combined together but the idea is the sensor in the tiles limits to tile heat to safe limits. As a DIY job removing the tile heat sensor may work but as a professional to remove a safety system is a clear no. So any timer has to be as well not instead of the tile temperature sensor.

Although the tiles are not of a material which will be damaged by heat below the heating mat there is often insulating material often wood which would be damaged by over heating. It's not just burnt feet which is the problem although clearly that is the main problem.
