From: john hamilton on 1 Jun 2010 12:20 We need to buy a freezer. The *chest* type is what we want with the lid on the top. 'Which' magazine recommends the Miele GT263 and for a hundred pounds less the Zanussi ZFC 321 which comes in at �260. The Miela has this feature which is suppose to expel the air inside, after the lid is closed. With less air trapped the theory is that it will not need defrosting as often as normal. Knowing that its just not easy to get an airtight seal, the suspicion is that it might draw the air out but; it will creep back in again anyway. Would anyone with experience of the Miele freezer know if its worth paying the extra �100 for this 'de-frost' feature. In other words does it work as a means of cutting out defrosting? Thanks for any advice.

Allowing moist air to enter the freezer will allow frost to build up, increasing the need to defrost. Will you be opening the lid of the freezer frequently? Once open, will you have the freezer lid open for long periods of time? How humid is the room in which the freezer will be kept? Cellars tend to be humid. Warm summer air can hold more moisture than cold winter air. Opening the lid in a humid cellar in the summertime will increase the need to defrost. Modern fridge and freezer seals are quite air-tight. Do you have cold air leaking from your current fridge? Probably not.

Probably not. We had little problem with one opened little. A tip I learn from the lab. Get flat sheeting to put under the lid, so air does not get whirled when you quickly open it up. Just slide the separate sections out of the way for access. Given a 6 foot freezer, you can make 2-4 sections. This can also be insulation foam sheeting. 1/2 inch. You should get very little infiltration. greg

For the freezer it's the absolute moisture level, not the RH, that counts - to be exact the amount that will freeze out at minus whateveritis you set it at. Warm, humid cellar in summer?
