Fan convector vs traditional radiator
Take a typical cheap radiator e.g. Milano Compact Type 11 1400x600mm (£104) It has these specs: BTU at Delta T30 2178 BTU at Delta T50 4208 BTU at Delta T65 5902 Watts at Delta T30 638 Watts at Delta T50 1233 Watts at Delta T65 1730 And stands 73/86mm off the wall The same sized fan convector, the Milano Mono 1400x600mm (£409) Has approximately double the heat output: BTU at Delta T30 4203 BTU at Delta T50 8166 BTU at Delta T65 11475 Watts at Delta T30 1232 Watts at Delta T50 2392 Watts at Delta T65 3363 And stands 134/147mm off the wall Other fan convectors I have found: Smith Eco PowerRad 1500x400 1.5kW @ 50degΔC = 20% better, but slightly smaller Myson iVector MK II iV60x160 BN 4.4-9.2kW @ 50degΔC = 4x better than standard radiator! Mitsubishi iLife2 Slim 80 1537x579x131 2.4-4.2kW heating @45deg flow and 20deg room temp (is that a delta T of 24deg? In that case the ratio is similar to the Myson)
