I have to fix a new toilet to my daughter's downstairs toilet.She has just had the floor retiled. The house has piped underfloor heating. I am just a bit concerned about screwing the pan to the floor and whether the pipes will be far enough down not to worry. The previous wc was plugged and screwed down in the normal way.Any thoughts please.

Turn it on, does it become warm in the area. If in doubt then don`t use screws however if the pan fixings use`s L brackets with horizontal screws I`ve seen blocks of wood stuck to the floor to replace the brackets. 😉

Epoxy resin. Or change the toilet to a wall mounted toilet.
Not easy to take out again if I epoxy it. Toilet already bought and wall mounting not possible anyway.
I agree with simong and bogrodder; screw cistern to wall and then run a nice bead of silicone around base of pan (use leveling packers first to ensure no rocking of the pan - cut them off flush with the porcelain). I've done this many times, can easily take out in future if needed but is rock solid for normal use. DO NOT consider screwing into floor.
If there is a toilet there already surely you should be fine? I personally wouldn’t be too worried if there was a toilet there already.
Not every engineer has thermal imagery to hand.
A joiner has put some boxing behind where the previous toilet was so the new fixings would be about 200mm away from the previous so I think it would be taking a big risk to drill new holes.
What the alternative? No toilet or get someone that has a thermal camera
Don't do it silicone it down to the floor and screw it back to the wall . Cheers kop
Seems a bit DIY to me mate. I wouldn’t except that in my house. So wouldn’t do it in a clients.
I posted this on purpose to see people’s responses. I know exactly what I would do (I posted it 2 posts down from this one) but there is another post on here still ongoing at the moment that is very similar to this one and the engineer and customer are debating it. Non of the professional engineers that commented on the other post have mentioned any of the ideas here. Just wanted to see how people would react
Old school it cement pan down ?
I will admit on some toilet pans I have solely fixed them to floor using silicone.
I sometimes won’t drill floor when pipes could be below.
Yes, if the pan ever came loose, then I could be accused of incorrectly installing it.
But on large pans on top of clean flat tiles and cistern screwed to wall, they are often very stable without any floor fixing, so silicone added will be very strong. In fact it is very difficult to remove.
Toilet pans are a big footprint so would be hard to pull loose if siliconed.
A basin will glue solid to a tiled wall if silicone used, so same on floor, but perhaps silicone might not grab to some types of tiles.

That method is flawed, heat spreads.....
In a ideal world it would be fixed via the L brackets but why take the risk if there is a underfloor heating loop there I could fit the pan securely without screwing down and have no problems, hit a pipe and its a hole different story i have respect for the other guys views but we all have our ways of working. cheers kop
Wouldn’t be any risk with thermal camera mate. You should be able to see where they run. In my opinion obviously

Go to Toolstation and buy a tube of Stixall. As others have said fix it back to the wall with screws and plugs and set pan down on a bead of Stixall. It WONT move after 24 hrs.
Or come off in the future.
Is this one still going .. lol
Side fixing toilet , block of hardwood stuck to the floor with sticks-like ****, screw into hard wood,
( pre drill first ) silicone seal around pan and “jobs a gud un “

Cheers for the confirmation. Got a link for your one? Would like a look.
