Heat Pump Tumble Dryers

Heat pump tumble dryers recycle the hot air they use to dry your clothes rather than venting it outside. This helps save energy, making it a cost-efficient option for your household.

John Lewis has a range of tumble dryers that include both vented and condenser models as well as heat pump tumble dryers. Learn more about the options in our guide to tumble dryers.

Cost

Tumble dryers are great for eliminating the need to hang laundry in the sun and to save space for storage, but they also are prone to using lots of energy. If you're looking to lower your energy bills, it might be worth changing to a high-temperature tumble dryer. They are more expensive initially, however they will save you money over time because of their lower energy consumption.

Heat pump tumble dryers work by reheating the air that was already warmed up during the drying process and results in lower energy bills than condenser models vented or vented. This type of tumble dryer typically consumes up to half as much electricity as a vented condenser model, and as such could save you up to PS173 per year on your utility bills.

When comparing the performance of heat pump tumble dryers to other types, there's generally a small price difference. However, it's important to consider the amount of energy that is being used and the frequency you'll use your tumble dryer. You'll need to take into consideration the wattage as well as your electricity bill when calculating the amount each tumbler will cost.

Vented tumble dryers use gas to dry laundry and are powered by gas from the mains which means they are a more expensive option when you're on a strict budget. The installation options are also limited as they must be installed in a space with enough ventilation to the damp air.

Condenser dryers take the moisture from your laundry by transferring hot humid air into an additional unit which is then converted into water. This water is then drained away either into a removable container that must be emptied manually or be plumbed into your drainage system for continuous removal. This allows for greater flexibility in the installation areas, however you will have to be prepared for additional maintenance by making sure the drain pipe is in good condition.

Energy efficiency

If you're concerned about your energy costs, a tumbler heat pump could provide substantial savings. The technology requires less electrical power to warm the air in the tumble dryer, allowing it to dry your clothes faster and at lower temperatures than vented models.

The dryers also make use of a coolant to liquefy the humidity in the air and then discharge it through the condenser. This means they consume less power than traditional vented models. They may take longer to complete your cycle of laundry than vented dryers however your clothes will remain looking and more comfortable for longer due to the lower temperatures for drying.

They'll cost you an additional $500 to $700 up front however the energy savings will easily make up for this. They are also more expensive and require adequate ventilation.

As with all electrical appliances, it's vital that the installation of a tumble dryer is done by an Gas Safe engineer. A vented dryer requires a long, flexible vent hose that is permanently connected to the appliance at one end, and a drainage point at the other end - either a drain or window. The hose is not shared or used in a way that could damage it.

Condenser dryers operate in a similar way similar to heat pump dryers. They use an electric element to heat the air and then expel the moisture via the condensation tray. They tend to be heavy-duty dryers with greater wet load capacities ranging from 6kg to 10kg and are more quiet to operate. They are more expensive to purchase than tumble dryers with heat pumps and they can't be installed without a permanent wall connection. The cost of running them is higher than heat pump dryers because they require more heat to evaporate the moisture from your laundry. They're less efficient than vented models. They still require electricity to turn the motor which rotates your clothes.

Noise

Tumble dryers produce plenty of noise however, the level of loudness is dependent on a variety of variables. The decibel rating can only be one of the many variables. The frequency of the sound also affects how loud it sounds. The sound may be amplified by resonant objects in the vicinity, such as cabinets, work surfaces or furniture, and could be affected by the acoustics of the room. The sound produced by the tumble dryer could be dampened by acoustic absorbent fabrics such as carpets, or it can be drowned out by other appliances that are operating within your home.

Heat pump and condenser tumble dryers are quieter than vented models, but it's important to remember that they're still loud. They are less harsh on fabrics and dry your laundry more slowly due to lower temperatures of air. They also have a longer cycle. They are less damaging to clothing and less likely to cause color loss which is usually associated with tumble dryers of the past that make use of high temperatures.

It is important to keep in mind that when you intend to utilize your tumbler dryer mostly together with a washer machine both appliances should be placed near each other to avoid noises or vibrations during operation. To prevent this issue, the washer and dryer stacking set is available for both types of appliances.

Heat pump tumble dryers need a constant flow of air to function, so they should be set up in a location that is well-ventilated in your home. You'll need to ensure that the vent hose is permanently connected to the appliance, and it's securely positioned outside of your house, rather than directed through a window or door.

The condenser tumble dryer, however does not require a permanent connection to a vent and can be placed anywhere in your home. It collects the leftover vapour and water in a condensation container that can be manually emptied or connected to a drain via a drainage tube which will automatically empty it.

It's possible to turn an unventilated tumble dryer into a condenser model with an conversion kit, however this will invalidate the manufacturer warranty and should only be carried out by a certified professional. The kits come with components needed to put in vents, as well with a small pump to remove condensation.

Maintenance

A tumble dryer with a heat pump is different from vented or condenser models as it doesn't require venting externally to draw out the hot air. The warm air that passes over your clothes is collected and then run through a condenser that is used to separate the heated water from the air. It is then collected in a water reservoir (sometimes called a tank) within the appliance. This means you'll have to empty the tank at some time however it also allows you to store the dryer in smaller spaces than if you needed to install a vent for the machine.

Compared to vented models, the heat pump model consumes approximately 50 percent less energy. According to Which? it is also less expensive to run. You can save between PS42 and PS51 per year. However, it's not a cheap tumble dryer to buy and you need to make sure you can afford the initial cost.

In general the heat pump tumble dryer needs little maintenance other than clearing the lint filter and looking for fluff around the heater unit each time. However, you have to clean the condensation drain often and it can take longer than a vented tumbler to dry your clothes.

Think about a sensor-controlled tumbler when you're looking to buy a low-cost model. It will shut down the machine after your laundry is done, preventing over-drying and damaging your clothes. You'll have to manually program your dryer's drying cycle when you have a large number of different clothes.
