While I am renovating my kitchen I would like to downsize the huge radiator I currently have (53x22x9). I have a smaller radiator (24x19x5) that I am not using and would like use in the kitchen in addition to an electric underfloor heating mat. The larger radiator has a 1 3/4" pipe feeding the it while the smaller radiator has a 1'' pipe feeding it. Does this impose any concerns with how this will impact the system as a whole? The kitchen is on the main floor of a two story house, and the boiler is down in the basement.
