Insulating a chest freezer

[nun_hunter]

I have a chest freezer in an outside shed. During the winter there is always condensation on it as it's so damp and wet around where I live.

Even during the last few days where it's been 18⁰C but raining it's still got condensation pouring off it and a puddle on the floor.

Is it worth trying to insulate it a bit better or is it beyond that sort of improvement and a newer more efficient quality freezer the more cost effective option?

The fact that it's cold enough on the outside to develop condensation makes me think it's probably costing more to run than it should.

Probably best to start by finding out what temperature the freezer is at and if its to cold.
If temperature is OK rap in kingspan or similar but insure the motor vents are clear

Good point I'll check that first.

I know little about freezers, but as an observation, having lived in both Sussex and Scotland, I have freezers in an insulated shipping container, and they routinely produce condensation. It’s worst in the humid months, but has never had an effect on their running. One is ‘new’ and one is ‘old’ and both behave similarly. I just accept occasionally I need to wipe up the odd drip/puddle as so far, no issues.

I did move a large rubber mat under the freezer to give some protection to the wooden floor. Good to know that both the old and new freezers were the same.

I drilled a dozen holes each end of the shed walls.1 patch above the freezer and the other directly opposite.
A covering of fine mesh to protect from bugs and touch wood no condensation issues.

If mine was producing that much condensation I would make it a coat of 50mm Kingspan

It's another anomaly the spec for a commercial walk in freezer is 150mm walls but a household freezer has somewhere between 60 - 75mm walls.
Just think thicker.

Isn't "think thicker" an oxymoron!?

Sorry,

CORRECT

The shed is already pretty draughty so I don't think that's too much of the issue.

I think I'll give it a go and see if it makes a difference.
