If solar energy, wind energy, or hydro energy is available, then the DC electric freezer operating cost will be low. However, the freezer must have power available at all times to keep the food storage at good freezing temperatures. When electrical sources become unavailable (the sun sets, or the wind stops blowing), freezers will require a battery bank for power storage. With hydro power, batteries may not be needed. Solar power however is not free. Solar power requires battery back-up and batteries wear out and must be replaced.
Gas Freezers can operate from stored LPG (Propane) gas or Natural Gas (a constant source of power). n some cases, a natural gas well is available on the property site and a natural gas freezer would be ideal. An un-metered well means free power to the natural gas freezer. Propane gas is also supplied either by truck to a permanent tank on the property or smaller portable tanks that can be transported and filled at a filling site.
Differences:
DC / Electric: Recovery time (time it takes for temperatures to come down or recover to the thermostat set temperature) when adding non-frozen foods – 2 hours
Retrieving a few frozen items: recovery time – a few minutes
It’s portable, if it’s operated with batteries or small solar cell.
Weight – 80 pounds lighter.
Gas / Absorption: Recovery time – when adding non-frozen foods recovery time – 8 hours
Retrieving a few frozen items: recovery time – a few minutes
It’s portable, mainly because of the power source (propane) being stored in tanks.
Weight – 80 pounds heavier because of the absorption system
Chest Style: The lid opening is at the top and cold air falls, so less cold air escapes.
Upright Style: These are open for less time since the goods are staring you in the face and are more accessible than the buried goods in the chest style. If the freezer is full of food then there is less air to fall out when the door is opened.
