In-Slab Floor Heating
VCD In-Slab
In-slab heating uses heating cables embedded in a concrete slab floor to provide home heating. The slab stores the heat and releases it to provide continuous warmth to the home during the day. It also takes advantage of off-peak heating rates and can be used in combination with other systems such as solar power during the day or as stand-alone heating using some day-rate energy.
In-slab heating is generally used in new constructions but can also be used on top of an existing slab, providing there is a sufficient top cover of new cement of at least 35mm.
Installation
In-slab heating involves the installation of an electronic element to the concrete reinforcement mesh prior to the cement pour. This is usually done as close to the day of pouring as possible. Cables are pre-tested before leaving the factory, tested prior to the concrete pour and then tested again before connection to the electrical supply.
Once the cement has been poured the new slab must be left for 6-8 weeks before the system is switched on.
In-Slab Floor Heating
-
Versatility
In-slab heating is not limited to tile floors. It can be used with various flooring materials, including hardwood, carpet, and laminate.
-
Higher thermal mass
The concrete in-slab heating systems have a higher thermal mass, which means it can store heat for longer periods. This can lead to more consistent temperatures and reduced energy consumption since the heating system doesn't need to run continuously.
-
Durability
In-slab heating systems tend to be more durable and long-lasting because they are protected by the concrete slab. Where as under-tile heating elements can be directly exposed to potential damage during tile installation or if the floor is ever renovated.
-
Cost efficiency
In-slab heating can be more cost-effective when heating larger areas because it leverages the thermal mass of the concrete slab, reducing energy consumption in the long run. Paired with solar, the slab can heat during the day with excess power produced.
