Like most items - all freezers aren't equal. It is worth delving into the electricity consumption VERY closely, sometimes the price saving can be eaten up by extra power costs within 3 or 4 years.I need someone to talk me off the ledge.... Im looking up Chest Freezers. I dont even want to hoard but it would be nice to know I have enough to not have to shop beef & chicken ect for a couple of months.
With an apples for apples comparison (same quality & same manufacturer etc) - a chest freezer should use much less power than a vertical one with similar capacity.
Reason - cold air drops & hot air rises. Open a chest freezer and the air does not immediately flow through it vs open the door of a vertical unit and the cold air drops instantly and the much warmer air (30-40+ degrees C) rushes up.
BUT (you knew that was coming...) if you are not organised with a chest freezer then it's cost increases due to digging for treasure. Best outcome is a chest freezer with moveable dividers (1or 2 or 3 if large enough). People are known to create their own dividers...
Always store like with like - don't just go for the largest empty space = more time searching later on.
Location, location, location...
If possible never have a freezer (or fridge for that matter) in a place (if possible) that receives direct sunlight. Ideally on a south eastern wall/position. Make sure you leave (yes this is more than manufacturers say & for a reason) at least 90 mm clearance ideally on all 3 non-door (vertical) sides as well as much distance as possible above (really only relevant for vertical models). Good 'paid' kitchen designers put only 2/3rd or 3/4 depth cabinets above so that the hot air can completely escape...
At least quarterly use your vacuum cleaner to suck/clean dust from air intakes (if your model has them). BE GENTLE!
Read 'instruction manual' (you know that thing you DIDN'T throw away with the packing materials...).
Before turning on after delivery/unpacking - let it stand at least 3 hours (longer is better) to ensure there are no bubbles left in the coolant otherwise that can cause a burnout and all the coolant past that point ceases functioning so the compressor has to work much harder & for longer.
