I'm remodeling my kitchen and I was leaning towards a radiant floor system, but the contractor plans to install toe-kick warmers because he thinks they are more efficient. The kitchen (about 10'x10' floor space) is on the side of the house with one wall exposed to the outside and a room above the kitchen.

The toe kick warmers will be less expensive. Are they comfortable? I worry that the heat will rise too quickly to make the bottom of the kitchen feel warm enough. Any advice will be appreciated. Thanks.
