The freezer in the garage or outhouse thread - successes and failures please?

Furts

A different angle to this thread could be does the freezer operate effectively at high temperatures?

With an old freezer in a detached unheated garage, which has a substantial tiled roof, the temperature can easily exceed 40 centigrade in the summer.

Thus, I would assume an old, poorly insulated freezer, would be working much harder and consuming more electricity than a modern one.

Mine does work and has done so for 20 years. But with rising electricity prices I am intending to introduce some ventilation to try and cool the garage.

Can't buy that one I'm afraid, there'd have to bee an almighty amount of glass in the walls for it to get to those temps, plus what temp would the house be at under the same conditions.

Mind, I do have that much stuff stored in the roof space of my garage that there is never any radiator effect.

I can honestly say my brick/block built garage with conventional tiled roof never over heats, but it is half below ground level to the rear and has no windows to the sunny sides,;);)

I do also have an insulated sectional door that does face the sun (on the odd occasion), maybe that helps

I think older (better made) freezers keep quite well in garages and depending on how sealed the garage is they work okay but maybe a bit harder when really cold or too hot.

The modern ones (cheaper built/cheaper parts) do not seem to cope well in garages (hence the warnings). I would advise to lift of a cold concrete floor by either blocks under a chest freezer or put a door freezer on a work top/cupboard to get it off the floor.

Which do you think is the coldest, the floor or the freezer?

But in respect of new versus old freezers, maybe most survive because they get relegated from the house when a few years old, or are bought 2nd hand because they are going into a garage where external cosmetics are secondary, either way they are generally older models, for now anyway.;);)

There is another question, has anyone ever had a freezer fail in a garage for reasons that can actually be attributed to the cold?

No doubt someone has but I'm pretty sure there can't be many.

- You can to decide that one!

Has anyone ever had a freezer fail in a garage for reasons that can actually be attributed to the cold? - And yes I have had a recent (new) freezer fail due to cold in the garage where one that is over 15 years old works fine in there!

I think you're right - though the statistics are probably skewed by the fact that older freezers (which didn't have this problem) were better built, last longer, and there are more of them (ours is at least 15 years old - possibly even 20) around.

The real problem is the warranty - the manufacturer/retailer can just point to the instructions and disclaim all responsibility for any failure whatever.

This extract from a current Bosch chest freezer manual is pretty typical (the UK climate class is SN):


Ambient temperature

The appliance is designed for a certain climate class. Depending on the climate class, the appliance can be operated at the following ambient temperatures.

The climate class is specified on the rating plate.
Climate class Permissible ambient temperature

SN +10 °C to 32 °C
N +16 °C to 32 °C
ST +16 °C to 38 °C
T +16 °C to 43 °C

Note!

The appliance can function within the ambient temperature limits of the specified climate class.

If an appliance in the SN climate class is operated at lower ambient temperatures, damage to the appliance can be excluded up to a temperature of +5 °C.

Which goes to prove what I was saying about not putting a new freezer in the garage, should have gone 2nd hand methinks;);)

Do you understand that, can't quite get what they are saying?

I used to deal with industrial refrigeration engs at work, I'm sure one of them told me it was largely down to the effects of condensation causing failures. His view was that's what you got on consumer products, industrial stuff was simply better insulated

I have a history of construction site thermometers stored in my garage after the sites are complete. A number have failed at 35-40 plus centrigrade. Clearly, the temperature rose above this.

I did have a garden /external thermometer that exploded- the fluid in the maximum limb expanded and blew the glass bulb off.

My house roof is too hot to be inside during hot summer days. I have never tried to record these temperatures, but the pv panels on top of the roof offer some shade and cooling. These do have a temperature read out. Over 60 centigrade is a common occurrence.

I don't doubt what you say in your case, but quite seriously my garage is used as a cold store even during summer, I never see any temps even approaching that of the outside even on the sunniest day.
And yes, my house roof space even though cross ventilated, ridge vents and several intermediate vent tiles, is impossible to breath in for more than a few minutes after a hot summers day.

Back to the garage, I have quarantine tanks for my fish keeping hobby in there, water temp never rises over 21 c.

I also use the greenhouse type max/min thermometer to ensure that conditions are kept correct, I have no issues of the type you mention.

The only thing I can say is that mine is totally open at the eaves, there is an air gap of 3" along the whole of both sides, meshed to keep out birds and vermin, the windows are also double glazed pvc as is the side door.

We have 2 very different garages, I think you need to pursue your ventilation plans;);),it sounds like the major difference.

Anyway, gone off topic, apologises all round.:)
