Finding new Fridge for use in Unheated Outbuilding


Postby Grandad99 » Tue Dec 20, 2016 5:24 pm

I've been using an old under counter fridge in an unheated shed, It's only switched on for about 2 weeks each year, during the run up to Christmas to hold the extra food.

It has packed up and not worth repairing so I'm looking for a cheap replacement. Info about some new fridges says not suitable for use in an unheated outbuilding. Would this apply to my very limited use?

Simply Build It

Unlikely you can find a fridge rated for use in unheated building, it can't maintain 4 degrees C if outside is lower than 4 degrees C. What I would do is convert a chest freezer, by replacing the thermostat in a chest freezer with something like the STC-1000 you can set the temperature to what you want, so same unit can be used as fridge or freezer, You just set temperature to -18 or +4 or even +12 to keep wine or +20 to brew beer.

Only chest freezer are suitable for non heated buildings, as they have no auto defrost and are officially always colder than outside.

I used an old fridge/freezer in the unheated garage which is frost free but the garage is part of house so although cold not that cold likely over 12 degs C which is normally the lower limit. I use it mainly to brew beer in, starts in freezer with STC-!000 set to 20 degs and a bulb to heat if required, after first 7 days moved to fridge section this now has no cooling just heating set at 22 degs to finish fermenting beer for another 7 days then bottled.

However if I wish I can remove the external STC-1000 and still use as fridge freezer. The Inkbird ICT 308 is a ready built STC-1000 no need to hard wire simply plug in so a freezer becomes a fridge.
