I consider that in future any complaints of over- heating should be tackled by making more ample means of the air to get away. There is hardly anything to chose as regards efficiency with either the Orme Evans square honeycomb, the Marston honeycomb and the Moreux honeycomb, but the Marston is by far the lightest, it is 20% lighter than the Orme Evans. Before we can decide anything as regards weight the Marston will have to be tried on the bumping rig for strength. For appearance I consider the Orme Evans is the best. We have received an Orme Evans square honeycomb radiator built up in brick form with wires soldered to the bottom tank, there is no difference as regards efficiency and weight but the bonded type which we have adopted is very much neater. | ||
