I got a lovely new rug and just realised the website says it is not suitable for underfloor heating. I have underfloor heating with an engineered wood floor. The rug is 7mm 100% polyester. I would love to keep it as the colour and size is perfect, I cannot find anything else suitable. However I am worried it will damage my floor. I would love some advice if anybody knows about underfloor heating and rugs. I do have an underlay to go under it which is apparently suitable for underfloor heating. Thanks.
