Why choose the Aspen Vertical Radiator 1800 x 540mm Double White?
1

8,397 BTU Verified Output

2

540mm Wide — Widest in the 1800mm Range

3

Double Panel — 79mm Depth

Double panel construction doubles the heat output versus the same-size single panel. The 79mm depth is a modest trade-off for the extra warmth.
