Radiant Heating

Radiant heating is a method of warming your house by supplying heat directly to the floors, walls, or ceilings of your house. The heat is then transferred to people and objects by the radiation of this heat.  This type of system also depends on convection, the natural rising of heat from the floor to the ceiling. As an article on Inspectapedia tells us, there are a number of advantages to using a radiant heating system:

The radiant heating system is unobtrusive - in fact not visible in the occupied space, saving floor space as well

Radiant heating systems are quiet and clean and require little or no maintenance (depending on the heating source: an oil fired heating boiler supplying a radiant heated building will still require annual maintenance).

Radiant heating systems save energy compared with comparable convective heating systems where the same fuel is being used to produce btu's of heat. Savings accrue from lower air temperatures as well as the omission of duct or pipe heat losses in the system.

Heating savings from radiant heat systems depend largely on the amount of thermostat set-back that the occupants find comfortable. Occupants of a radiant-heated building often are equally comfortable (compared with other heating methods) setting back the thermostat 5 degF - about a 20 to 25% savings on heating fuel expense.

Radiant heat "feels special" or "like being heated by the sun" - (an opinion difficult to verify objectively).
