A Heat Pump is a small portable heater designed to operate with a Sheltersuit. A Heat Pump is designed to be plugged into a Sheltersuit but can be used independently. When activated, the self-contained battery is good for an average 30 days continuous operation. The heat pump can also be used to heat or cool a shelter, such as a tent or small cave, but its duration is reduced considerably
A combined Sheltersuit and Heat Pump weigh 2.0 kg.
