Is radiant heat expensive to run?

Radiant heat can be expensive to run, depending on the type of system you have installed. Electric radiant heat systems are typically more expensive to run than hydronic systems, as they require more energy to heat the air. Hydronic systems use hot water to heat the air, which is more efficient and cost-effective. Additionally, the size of the space you are heating and the insulation of your home can also affect the cost of running a radiant heat system.
