Hi,

I'm in the UK and have Step Warmfloor heating on my ground floor and I'm looking for a timer that works on 24v so I can control a small off shoot of my system which just acts as a floor warmer in my small bathroom,  its linked to the DigiLux controlling the main area but I thought as the bathroom floor only needs to be warm morning and evening I'd put it on a timer. I have tried a normal battery controlled 240v (UK system) 7 Day Digital Timer with no luck, the programmes switch on and of but the 24v power does not get through. The 24v power travels perfectly through the normal 13amp 3 pin plug and socket without the timer in place. I estimate under full load the floor only draws about 65 watts as its only a small area in a bathroom.
I don't seem to be having any luck with electrical supplies in the UK and I've tried Truck supplies as they work on 24v but no luck.
Any ideas how to make this work?

Many thanks,
Richard

It should be possible to put in a timer switch that can handle the 2.7 amps at 24v and achieve what you're trying to achieve, but the switch and the time spent looking for the right one is likely going to be more expensive than the power the floor would use if it were just left on.  65w at 230v is less than .3 amps.

This explanation is made pretending that the elements, when on, will always draw that much power even though they will not due to their self regulating properties.

As for what switch, or where to get it, I'm sorry but that's outside our area of expertise.

Your probably right but even though its a small area ( approx 1.25 m2) it still seems a shame to waste the power but I guess from my research so far when I find a timer the cost will be prohibitive.

Thanks for your interest.

Studies from the "Sick Building Syndrome" show a direct relation between indoor climate and symptoms such as fatigue and headaches.  Research shows that thermic indoor climate is also related to productivity.  The level of comfort with radiant heat at lower temperatures increases productivity by 20-30%.
