08 HI-LO Round Top HI-LO ROUND TOP The hi-lo Round Top is our signature product. Engineered by QRL experts and featuring our unique third-generation technology, it is also the most efficient panel radiator on the market. Put simply, the hi-lo Round Top is the better choice for performance, quality and durability. With a heat output that’s 10% * higher than competitor radiators of the same size, you can choose a smaller radiator and still get the same results – meaning more pennies in your pocket. The savings don’t stop there, either. Thanks to its super-efficient build, it also uses less water, which takes less time to heat. This means your rooms get warmer, faster and your bills stay low. For an even more efficient way to heat your home, the hi-lo Round Top is fully compatible with low-temperature heat sources, including renewable technologies (e.g. heat pumps). * Comparisons based on existing competitor catalogue outputs (Double Convector) HI-LO Round Top Actual Dimensions Mounting Details Note: Dimensions H1, H2 and H3 refer to the lugs on Double Panel Plus and Double Convector radiators.
