    Hi all. I built a garden room last year in first lock down. Used as a bar with 2 beer fridges in there and beer machine on counter. All fully insulated in walls, plasterboard and skimmed. Have a heater for winter when needed. But jeez this weather and heat from 2 fridges. Any recommendation on how to remove heat. 1626799199044247096049973510537.jpg

    Leave the fridge doors open :D

    You could also try a fan to push the air around and encourage some circulation

    you can have a small extractor fan above and behind the fridges, especially if they are undercounter or integrated.

    Reading about the small Ac units....says they are poor. Leaving the fridge doors open is clever...but warm beer no thanks. :(. They are under counter fridges but would an extractor fan actually work that well anyway, and vent the heat. Might just have be a fan.

    Leaving the fridge doors open, will just make for even more heat produced at the back of the fridge - it is self defeating.

    Caravan's use a vent at the bottom rear, vent at the top rear and seal the fridge to the wall/ from the rest of the caravan. That way all the heat flows straight out and the fridge is able to work more efficiently - could you do something like that?

    An extract fan, placed up near the ceiling or as high possible will help draw air in and extract heat from where it collects near the ceiling. A ceiling mounted fan to stir the air will also help anyone in there to stay cool.

    Thanks for reply harry.
    Ceiling fan is out of the question for head room limited. I'll look into the caravan vents idea. Will a extractor fan actually take the heat out of the room then? Only thought they were for bathrooms to take moisture or steam away.

    They are for extracting air of any sort, including moisture laden air in bathrooms. In caravans, some add a 12v computer fan, to improve the cooling of the fins at the back of their fridges in hot weather.

    It's about air movement,

    Though to get the cabin physically cooler you'd need a lot of air flow and it's basically not going to be worth it.

    A different colour to the building may help as it is dark colours soak heat, whereas light colours reflect it

    how about a wall fan? I bought one for about £40 for my bedroom and it works a treat, and is not in the way like free-standing ones.

    Do those windows open? Getting air flowing through will help

    Prevention better than cure.

    White EPDM roof
    A reflective awning on the side which catches most of the sun

    Mrs wouldn't let me paint it any other colour now anyway.
    Roof is insulated yeah. And rubber roofed grey.
    Windows don't open unfortunately. To be honest, I wouldn't leave them open when not in or at work anyway. Just ordered a woozoo fan to see what that does. Still may put a vent high up on wall. As soon as I get home I open the doors to get air flowing and it cools down slowly. Bloody hot at moment not helping

    To remove heat you need flow.

    So the doors are open, but really you need another point of exit somewhere.

    The same with installing a fan, you'll need a point of exit.

    Also really like that, I want to do something similar in my garden but need to work out a way to build over a ditch as filling it in isn't really possible due to logistics through the garden
