What Is Radiant Heat?

Radiant heat is a heating method that warms objects and people directly through radiators or in-floor piping, rather than heating and circulating air the way a furnace does. Boiler-based systems in older homes typically deliver heat this way through cast-iron radiators.

This definition is pending sign-off from a licensed HVAC reviewer.

Why It Matters to You

Radiant heat from a boiler is often described as more even and less drying than forced-air heat, which is one reason many older Western Suburbs homes with existing radiator systems keep their boilers rather than converting to a furnace.

Practical Guidance

If you're weighing whether to keep a boiler system or convert to a furnace, factor in that converting means adding ductwork your home may not currently have.
