Ah heck; I'm getting confused! But what is new! [img]/forums/images/icons/tongue.gif[/img]
You want long term heat? Always go with thermal mass.
You want quick heat? Go with convection/radiant.
You want consistence? Go with a combination.
The heating systems will work mainly on the thermal mass but you have radiant/convection for quick surface comfort.
