We are renovating our kitchen with addition and wanted to do radiant (hydro) as the primary heating source for the room. It is about 450 sq ft. total.

My concern is that the radiant would run off our existing boiler(3rd zone). Given the nature of radiant that it needs to stay warm to be effective I wonder if it would wind up running our gas boiler much more and be less efficient than going with toe-kick radiators.

Currently we usually are out all day and have the heat go down to 60 when out and then back up when we get home at night.

Also, we plan to run this under engineered bamboo.

Any suggestions on whether toe-kick or radiant would be more efficient?
