How much does it cost to run a dehumidifier?

As the title really.

Just bought one from screwfix for my new garage and ideally would like to leave it on 24/7 but would like to know what the likely running costs would be. It's this one by the way:

The single most important thing about maintaining a dry garage is insulation. It's no good drying and/or warming the air if it then escapes and is replaced by cold wet air and/or moisture through the floor, walls or ceiling. And garage doors are particularly difficult to insulate and seal.

If the OP provides some details of the type of garage he has, we might be able to make some suggestions.

Ok then.

It is a double garage 7.5 x 6.0m internally with a 2.4m ceiling height. The walls are two 100mm blockwork skins with a 100mm insulated cavity.

The garage has a room over and I have installed 100mm celotex between the joists with 50mm under the joists. I have also installed 170mm mineral wool insulation under the floor on the upper floor.

The garage doors are 45mm insulated sectional up and over doors with rubber seals.

The slab is 100mm concrete on 200mm type 1 stone.... Enough info?

Cheers
