You’ll also need to consider which type of heat source you intend to use. This type of system is more expensive however. The pipes are generally 16mm diameter, so this arrangement gives you 50mm concrete cover over your pipework.Īs a final option you might look into a low-profile system such as Uponor Minitec which can be installed on top of an existing slab and is only 15mm-20mm thick. Then a second layer of steel should be placed over the pipes which helps stop the concrete surface from cracking. There should be two layers of steel mesh – the bottom layer on 20mm chairs, with the hydronic pipework tied on top. In this case, we recommend the topping slab to be 90mm thick. This is common if there is an existing structural slab, or if your floor will have a polished concrete finish – the topping slab has different properties to the structural slab which makes it better for polishing. In this case the hydronic pipework is installed within the structural slab.Īlternatively, you might pour an additional topping slab over your structural slab. Once the mesh has been laid, we can install the pipework, ready for the concrete to be poured. In a new slab, the easiest and most cost-effective method to install the pipework is to tie it to the steel reinforcing mesh. But if you’re remodeling an existing property, you might already have a floor slab. If you’re building a new home, chances are you’re pouring a new concrete floor slab. So you’re building your new dream home, and you love the idea of comfortable, radiant heat keeping you warm all winter? Here are 3 things you’ll need to consider before you start building.
