A condenser hotwell is just a device that can be used to convert heat energy into electrical energy. The device works by using a condenser and a battery to provide heat. It is a device that will provide heating for the entire home. With a free-standing unit, it is generally used in larger apartments or houses where the electric lines are accessible and where the housing area is large enough to accommodate this equipment.
Since the term condenser simply means a closed container, it does not mean that it is a sealed one. The condenser can be any vessel that has a shallow lip. For example, a bowl can be used to hold the air inside the unit. It is always best to remove the material and reseal the unit. Then, use metal foil and put it inside the container. This will prevent moisture from entering the unit.
If the condenser is placed inside a metal container, the metal foil can be removed and replaced with cloth. This will then provide insulation to the interior of the unit. The metal foil can also be utilized to form a seal over the unit. It can also be used to place insulation between the container and the insulation. This will stop the unit from causing a draft while it is working. The freezer in the unit should always be on to prevent the unit from freezing. Sometimes the condenser can be connected to the freezer through a pump if the unit is cold when the compressor is operating.
