hi ...looking at getting a new double convector radiator for living room ( rad measures 1200 x 500 )...i have found a few that i like..and i understand that btu's relate to heat output etc but on one site the following is written.."Output BTU's @ 50 degrees: 6527btu...
Output BTU's @ 60 degrees: 8362btu".....what exactly is meant by the 50 degrees and 60 degrees and why two different readings? the radiator is to heat a room approx .. 5mtrs long x 4 mtrs wide x 2 mtrs high... would this radiator be ok for that ? and again what do the 2 different btu's figures mean ?..hope you understand what i am saying....many thanks in advance

50'c & 60'c is referring to the water temperature flowing into the rad
it is common to run Condensing boilers at a lower temperature to maximise the efficiency, the hotter the water the greater the output of the rad. this maker is being helpfull by giving outputs at difrent water temperatures ;)
