Location of thermostat for underfloor heating in bathroom

[scotster]

I've had a look through quite a few posts on this but haven't seen a definitive answer so any help welcome.

My electrician has done a first fix for an electrical underfloor heating thermostat in my bathroom. I have read that this may not be allowed but other posts seem to say that it may be OK depending upon the zone and ip rating of the thermostat. The plasterer will be here in a week and I wanted to check this before it becomes more difficult to rectify.

The thermostat will be in Zone 3 and the electrician says its fine and I hate to question him further.

My house has a couple of 30mA RCD's fitted in the main consumer if that is at all relevant and the heating will be basic mat stuff of only 4 square meters in size.

Regards,
Scott,

Is your bathroom big enough to get it outside the zones?

Question him further. There is no longer anything called "ZONE 3"

Thanks for the replies.

I can do some measurements tonight to see if it is in Zone 3 but Taylortwocities is implying thats not worth doing??

Any more clarity on this please? Im more than happy to challenge my electrician but the two posts here seem to conflict.

If someone points me to the Part P regs document Im more than happy to do some more homework.

All help welcome.

There is only Zones 0, 1, and 2 now.

Anything past zone 2 is now outside of zones completely.

Have a look at the wiki for bathroom zones.

Cheers Londonboy.

So back to the Original Post. Is my electrician correct in saying he fit the t-stat in this zone?

What thermostat is it?

 

[scotster]

Not sure as he hasnt turned up with it yet. We requested something like an Aube digital one or anything similar http://www.floorheatingsuperstore-shop.com/aube-digital-thermostat-th-132f-982-p.asp

Certainly not IP compliant in any way by the looks of it.

The thermostat will be 1.3 m away from a sink and 1.5 away from a bath so according to the Wiki guide it is beyond zone 2.

Any conclusions please?

what kind of UFH system is it? i presume each room has its own dedicated zone with a room stat contorlling its dedicated actuators. Many of these are wired into a control unit which are 12v DC which will be fine

Sorry Safesinbad.

Its simple matt electric UFH heating for under tiles.
Thermostat controls just the bathroom.

Let's hope he's conversant with Section 753.
