I noticed that you have the same radiators that I installed last year with my new boiler. I LOVE these radiators! They put out nice heat. Most homes with a boiler here in US use baseboard heat (finned copper pipe with shroud) which you need to put along every single wall to heat and they still are not good! I heat my 1300 SQ FT home with four 48x24" and 3 smaller ones. And they look a lot nicer too.
