Cheapest system: Electric Cable at $2,410.75Electric mat systems are the easiest to install for DIY projects and work well for single rooms. Electric cable gives more layout flexibility around obstacles. Hydronic systems cost more upfront but are the most energy-efficient for whole-house heating and pair well with a boiler or heat pump.

Electric cable requires careful spacingCable must be spaced evenly (typically 3 inches apart) and secured to the subfloor with strapping or mesh. Uneven spacing causes hot and cold spots. Professional installation is recommended for best results.

This is a material and labor estimate only. Actual costs vary by region, system complexity, and existing infrastructure. Hydronic totals do not include the boiler or water heater. Always get multiple contractor quotes before committing.
