Because condenser dryers do not use a constant stream of heated air like conventional tumble dryers, they cannot heat and dry clothes simultaneously in the same way. Condensing water to remove it can be a time-consuming process comparatively. Condenser dryers may take one or two hours to handle a full load and do not usually get clothes as warm or dry as alternative options.
Condenser dryers are designed to be compact and efficient. This helps them fit in a wide variety of places and save money on energy costs. It also means that they will not be able to handle the same size loads as traditional dryers. A normal condenser dryer may need two loads to handle the same amount of clothes that a non-condenser alternative could manage.
Sometimes condenser dryers have separate hot air motors that they use to run the evaporators and cycle the air back and forth from the dryer. These motors may be improperly connected with other systems in the house, such as the air conditioner system. This can cause a disconnect between how the thermostat reacts to the temperature of the air and how the dryer runs, putting temperature control and dryer operation at odds.
Condenser dryers typically have condenser tanks where they store the excess water drawn from the air. This water must be emptied regularly. If the water is not emptied, the dryer may not start or will not be able to operate at peak efficiency. A number of electrical problems can also occur, from fuse and breaker problems to electrical programming issues.
