No. Unlike the fixed Bromic heaters, the Eclipse Portable plugs in. What it does need is a suitable outdoor-rated socket on an RCD-protected circuit that can carry the load - if you do not already have one on the terrace, that part is an electrician's job.

On a level, firm surface, yes - the base has concealed wheels and the assembled unit rolls easily despite weighing around 173kg. It will not go up steps or across soft lawn, so think about where it lives before you assemble it, because the ballast makes it a two or three person lift.

The 145kg base gives it far better stability than a typical mushroom heater, so ordinary gusts are not a concern. But radiant heat is carried away by moving air whatever the heater, so on a genuinely exposed terrace you will feel the benefit far more with some shelter - a wall, a screen or a veranda roof.

It uses the same 700mm ceramic-fascia head and covers roughly the same 13m2. The practical difference is geometry: a ceiling-mounted head sends heat straight down over a table, while the portable arm angles it across a seating area. Both work well, they just suit different layouts.

It is IP54 rated in double-coated corrosion-resistant steel, so it copes with British weather outdoors. It will last considerably longer if you cover it or move it under shelter through the worst of the winter, and if you are near the coast, rinse and wipe the head every couple of months.
