Range cooker too heavy for insulated floor & screed?

[Marybelle]

Hi All

We're about to lay insulation on top of the distribution pipes and concrete slab. After that we're putting in UFH and then the screed. In the kitchen we're having a big cast iron Esse.
Will the celotex insulation be ok with something that heavy on top of it? we are concerned that it might not be a solid enough base?

Thanks

What does the thing weigh and what's it's footprint?

Will likely be fine though.

Its approx width is 1.4m and depth 60cm.
Weight is going to be around 450kg I think.

Thanks

Good. Now call celotex and tell them what you've told us. If no good then I'd omit insulation under there and make it all solid. Obviously that's a bit naughty though.

If you're really lucky someone else will be along in a minute and give you a more useful answer

Frankly if I were specifying this set up I'd be on the phone too. Or talk to your UFH supplier, its not something that unuasual.

..Unlike you spilling of the word.... deliberate spolling mistike God i'm boring.

Thanks All. Think we're going to just put a solid slab down in that spot to be on the safe side.

Or decrease the insulation depth in that area and increase screed depth? I'd stick 20mm of marmox/insulated tilebacker where the normal floor inso would go, and use the extra depth gained for a thicker screed/concrete.

A compromise, but at least you end up with some insulation, better than none.


If celotex gave the ok, I'd still probably put a 10mm steel plate under it, to distribute any point loading when installing, or from the feet/base.

Have you seen the price of steel plate recently ?

Have you seen the price of Esse cookers!
I'd use an old roadplate tbh.
