Here are the important facts and steps mentioned in the article, relevant to the keyword 'heated driveway DIY': 1. Ground preparation and compaction are crucial for optimal performance of the heated driveway system. 2. The spacing of the heating cables should be planned in advance based on desired heat output. Data from ASHRAE can help determine the heat requirements for melting snow in specific geographic locations. 3. Limit the number of times the cables pass through crack control joints and use joint jumpers for protection. 4. Start by attaching the cables to wire remesh following the planned layout. Elevate the remesh on castle chairs to position the cables in the center of the concrete pour. 5. Install jumpers at crack control joints. Install the activation device and control units and make the necessary connections. 6. Run any tests required by the manufacturer before pouring concrete over the snow melting system. 7. Take care to avoid damaging the cables while pouring concrete and run any additional tests required by the manufacturer. 8. Once the system is installed, it can be operated with an automated activation option or manually with a switch or timer. Watch the weather and activate the system when snow is expected.
