What are the Suitable Floor Coverings for Hydronic Heating

Slab Heating certainly has many benefits, however understanding which floor finishes and coverings are suitable and not suitable is important to understand before you make your floor covering selection.

In this article we hope to give you a greater understanding of what floor coverings are suitable for slab heating, and which are not.


Slab Heating with Polished Concrete in a Melbourne Office

Polished Concrete and Slab Heating

Polished concrete is an ideal finish for slab heating. The concrete is the direct conductor of the heat energy that is transferring into your room and this is how you will get full benefit of the slab heating system. We request that the thickness on top of the pipe is higher at around 70mm to prevent any hairline cracking. As all other floor coverings will hide any hairline cracks we request only around 50mm on top.

Tiles with Slab Heating

Porcelain and Ceramic Tiles are great conductors of heat energy and are therefore a recommended floor covering for slab heating. As they are covering the slab and therefore will hide any hairline cracks, we can install the pipes with only 50mm between the slab surface and top of the slab heating pipe.

Slab Heating with Marble natural stone Flooring in Melbourne

Natural Stone Flooring with Slab Heating

Natural Stone Flooring such as marble, granite and terrazzo are really good conductors of heat energy. Remember the heat that radiates from large stones at a beach on a hot summers evening? This is an example of radiant heat being released slowly over a long period of time even though the sun has long set. This is exactly what hydronic slab heating replicates and why we recommend natural stone flooring with hydronic heating.

Slab Heating with Engineered Timber Flooring in Melbourne

Engineered Board with Slab Heating

Engineered Timber board is ideal for slab heating. Similar to laminate flooring the manufacturing process gives engineered board a stable and strong base that won’t react to the heating. The top wear / dress layer is available in a wide range of finishes to match any natural timber or bamboo.

Slab Heating with Laminate Flooring in Melbourne

Laminate Flooring with Slab Heating

Laminate Flooring is manufactured by laminating layers of wood together in opposite directions. The laminate process gives it far more strength and stability that the same thickness of a natural hardwood and is why we recommend it as a suitable floor covering for hydronic floor heating. We highly recommend that you check that the manufacturer will warranty a laminate with a heated floor and if special installation requirements are needed.

Slab Heating with Carpet in Melbourne

Carpet Flooring with Slab Heating

Carpet is a suitable floor covering for slab heating as long as the carpet underlay is suitable for heated slabs. Also be aware that it doesn’t conduct heat energy so it won’t feel warm to the touch. The radiant heat will still warm your room as it will travel through the underlay and carpet. So carpet is suitable but these two things need to be taken into consideration.

Vinyl, Hardwood and Floating Floorboards with Slab Heating

Floating floor boards, natural hardwood and vinyl are not suitable for slab heating. This is because when heat is introduced to a natural timber, it will react by bending, bowing and moving. Vinyl may discolour and the heat may work against the glue. Consider using a different floor covering as described above.

Caution: Always Consult your Flooring Supplier

Always consult your flooring supplier as to weather your chosen product will remain under warranty when installed onto a hydronic heated slab floor. This will give you peace of mind in your product selection.
