Condenser vs vented vs heat pump. Which one Is Useful?



Dryers with condenser coils are the most popular. The tumble drums are heated by blowing air over an electric coil. Heat and moisture are emitted into a container as vapour and condensed into water.

Condenser dryers are closed systems. The air passes over a heating coil and into the drum. The air is expelled into a condenser chamber, where water is extracted, and the dry air is heated and returned. Collecting water needs to be emptied regularly.

Condenser dryers are generally slower and less energy efficient than vented dryers. Additionally, they often have a “quick dry” feature, which is generally inefficient.

Condenser dryers generally come with medium (7-9kg) or large drums (10kg and up). Additionally, they are usually heavier and are not really suitable for mounting on a wall.

Upside: closed system – no venting

Downside: Fast, needs to empty a water reservoir, weighs a lot and cannot be wall-mounted.  Poor energy $ per kg/minute drying time ratio.

Emptying the water reservoir weighs a lot. A fan draws external air over a heating coil, blows it through the drum and expels hot, moist air out a vent. Air should vent to the outside.

It is fast, requires a water reservoir to be emptied, weighs the clothes before they are dried, and starts on a delayed timer to prevent over-drying or using low-price electricity. These are better and stretching to this level will get you the best heater/dryer.

A disadvantage is that it is slow, needs to be emptied regularly, is heavy,rating as low as £150. Here, air here is blown over a heating coil into the tumble drum and expelled through a large pipe, much like that used on a portable air-conditioning unit.

Negatives: Slow, must empty a reservoir, very heavy, cannot be mounted on a wall. either through a window or permanently fitted through an external wall.

Also a disadvantage is that it is slow, needs to be emptied regularly, is heavy,and mid. Thus, vented dryers are trickier to place in a room, with their installation a more complicated

It needs to empty a water reservoir, and needs the help of a professional.

extra programmes makes them more efficient and gentler on clothes, but this usually comes at a higher price. A reverse-action setting – which changes the direction of the drum towards the end of washing – is useful for avoiding tangled or crumpled clothing. 

Upside: Cheaper to make and buy. Quick-drying. Stackable or wall mount. Good energy $ per kg/minute drying time ratio.

Downside: hot, moist air needs to go somewhere so vent if you can or open a window in the laundry. Shorter replacement cycles. Not as gentle on clothes as one heat/time fits all. Can ‘ball’ clothes leaving damp patches inside.

Heat Pumps

Heat Pump

Condenser dryers without heating coils are heat pumps. The mini-air conditioner/fridge is a closed-system model. When a compressor compresses refrigerant gas, hot air is extracted and blown into the tumble drum during the process of blowing air through the coils. From the coils, water is collected. That’s why it’s cold inside the fridge and hot outside.

The energy efficiency of a compressor is much higher (7-9 stars) than that of a heating coil, but humidity and temperature can affect the performance of a compressor. Additionally, heat pumps require periodic draining of water reservoirs.

They are the gentlest on clothes since they use far lower temperatures. However, they can also take longer than condenser systems.

Operating costs for heat-pump dryers are the lowest. Although they are the most expensive at first, they also represent a larger investment. They’re particularly suitable as a long-term solution for those who frequently tumble-dry their clothes.

The heat-pump dryer is similar to a condenser dryer in that it has a water tank, but the heat is reused. A condenser dryer, on the other hand, does not have a heating coil, so it works like a refrigerator and air conditioner.

Tumble dryers also send hot air into the drum, but here the warm vapour is compressed and passed through the evaporator. The extracted water is pumped into a tank (or directly into a drain if you’ve attached the optional hose). The difference is that the warm air is recycled and reused, not dumped outside.

Since condenser tumble dryers repurpose the hot air, they are more energy efficient than any other type of dryer, but they can take longer to operate. Newer models, however, are offering faster cycles. Similarly to other tumble dryers, the best models tend to be on the more expensive end with features such as smartphone controls and extra programs. Generally speaking, they tend to be the quietest and gentlest on textiles because of their lower temperatures.

Their size is only available in medium (7-9kg) or large (10kg or more), and they cannot be wall-mounted.

Upside: low energy use. Said to be gentler on clothes.

Downside: Long time to dry. Cannot be wall-mounted. Need to empty a water reservoir. A lot of tech goes wrong. is a leading supplier, stockist, manufacturer & exporter of SA213 T12 Tubes. Get in touch with us for the best rates & availability.

  1. There are two types of tumble dryers, heat pump dryers and condenser dryers, that are both designed to dry clothes efficiently. In spite of this, the main difference between the two devices is the method they use to generate heat to make them work.
