Concrete Slab Underfloor Heating Concrete Floor Construction

Response from the underfloor heating pipes is slower than with the screed method but because the thermal mass is greater it will hold more heat energy for longer.

Concrete slab underfloor heating concrete floor construction.

Embedding your radiant heating system into a concrete slab is one of the most cost effective ways to install it and most energy efficient being that concrete is a great thermal mass. There are generally two types of floor construction those of a simple concrete slab construction and those which incorporate a reinforcing wire mesh grid at mid level in the floor. There are arguments for and against both but if you are to use an underfloor heating method of some kind the insulation is often placed on top of the floor slab under the screed. However it is possible to achieve this effect on a suspended floor by means of laying the pipes in a dry screed pug biscuit mix or with aluminium.

Here screed is being laid over warm water underfloor heating pipes to the correct depth in this install using products by the wunda group image credit. The advantage of a is one concrete slab however this build up is not always suitable in all circumstances. Note that on the 24hr heating requirement the floor insulation is under the concrete slab to allow the thermal mass of the concrete to absorb the heat. Floor coverings must be fitted after the screed is dry.

Warmafloor systems can be incorporated within load bearing structural floors in a variety of applications from factories and warehouses to sports complexes. Since the concrete forms a structural slab the thickness should be 150mm subject to local planning regulations. Quite simply concrete floor radiant heat is a system of pex tubes that carry hot water throughout a concrete floor or slab. Conventional floor build up is dpc insulation concrete tile or polished concrete etc.

Radiant heat can be an electrical heating element embedded into a very thin concrete overlay then tiled carpeted or have wood flooring installed over it. Wunda group if the pipes are housed in the concrete floor slab sometimes the case for new homes this is could be 150mm thick and give a reaction time of over four hours. As the heat that is stored with the concrete disperses it is evenly distributed into the room. Depending on the type of building construction or standards there are a number of methods for laying underfloor heating pipes in concrete floor structures.

This is the best choice for new construction and areas receiving new slabs. In concrete screeded floors the screed acts to diffuse the heat across the surface providing an even temperature at floor level. This is a wet floor construction gives a high heat output and works well with a longer heating cycle. Underfloor heating traditionally relies on the thermal mass of a concrete floor or screed for heat.

The floor insulation can be placed under the slab or between the slab and the floor screed.
