Hi,I have a friend who wants his ensuite to have a heated floor which means ripping up existing tile and putting in ufh,this is not a problem,what he wants to know is can I unhook the existing baseboard heater (220v) and use that to power the heating mat,I would probably do it at my house and I'm sure there's a hundred "by the code reasons"I can't,but theoretically,can it be done?They're retired and we're trying to save a bit of money,I'm doing the job for free and would like to save them the expense of having a sparky run a new line which is what I've always done in the past,thanks,Mike

If its 13amp it should be ok. Is it off a ring a radial or a spur? That what id check first

my electrician insists a switched spur is used for the ufh too.

It must be RCD protected, either on the spur or the fuse box.......

I'm in Canada,to me a spur is on a cowboys boot,what is it to you?I was just going to hook up the power from the baseboard heater(220volt)and change the thermostat over,they both use the same amount of electricity,Dave,Doug,Phil,Sir Ramic,what do you guys think,remember it's for a good cause,my friend is a retired carpenters union president so it won't be a hack job

Sorry i just realised where you are! The wiring in the UK is mostly ring mains which im guessing is differetn to you guys? You can then 'spur' from the ring with a single wire to a switch, preferable to extend the ring though

Leave the electric UFH mat with cold tails for connection by a qualified electrician.
Test it during installation for resistance and confirm it is within the manufacturers variants, draw your plan, mark the postion of the floor sensor, and fill in the warranty.
The final connection for the ongoing guarantee and signature is that of the Electrician and is handed to the householder for sending off to the manufacturer.
Failure to comply will nullify the guarantee!

In the UK.. a heating mat will in theory be an extension to a wiring circuit and is governed under regs to be tested as TJ says above..
