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 - rested prior to the concrete pour and then tested again before connection to the supply.

Once the cement has been poured the new slab must be left for weeks before the system is switched on. The slab acts as a heat storage bank which warms up during off-peak times - while heat dissipates from the slab throughout the day.

The system can also be set to come on for a pre-determined at-day rate as heating requirements increase towards the end of the day. Woods Sewer and Drain offers a full design, quotation and installation service for in-slab heating.  Installation includes the supply of heating elements, thermostats and wiring for the system.
