Tumble Dryers

Introduction

A good tumble dryer turns laundry day from a chore into a breeze—especially in the UK where line‑drying isn’t always practical. But which type should you buy? Heat pump, condenser, or vented? What drum size is right for your household? And how much will it cost to run? This guide answers those questions in plain English, so you can pick a dryer that’s kind to your clothes and your energy bill.

Tumble dryer types (pros and cons)

Heat Pump (most efficient)

How it works: Recirculates warm air via a heat pump to dry at lower temperatures.
Pros: Uses up to 50–70% less energy than condenser/vented; gentler on fabrics; typically A++ to A+++ energy ratings.
Cons: Higher upfront price; cycles can be longer (though many now have faster modes).
Best for: Most households wanting low running costs and fabric care.

Condenser

How it works: Extracted moisture condenses into a tank (or drains via hose); no external vent needed.
Pros: Flexible placement; cheaper than heat pump.
Cons: Higher energy use; runs hotter; can warm the room.
Best for: Mid‑range budgets and homes without easy venting.

Vented

How it works: Moist air expelled outside via a hose/vent.
Pros: Usually the cheapest to buy; simple tech.
Cons: Needs an external wall/vent; higher energy use; heat loss to outside.
Best for: Tight budgets and utility rooms with an external wall.

Drum size: what capacity do you need?

7 kg: 1–2 people or light use (sheets/towels may need two loads)
8 kg: Small families or frequent gym wear
9 kg: Most families—handles bedding and towels comfortably
10–11 kg+: Large families, bulky items, king/duvet loads

Tip: Match washer and dryer capacity where possible (e.g., 9 kg washer with 9 kg dryer) to avoid half‑loads.

Running costs (UK 2025 ballpark)

Assuming 30–35p/kWh and mixed cycles:

Heat pump: ~0.5–1.0 kWh per cycle (£0.15–£0.35)
Condenser: ~1.7–2.5 kWh per cycle (£0.55–£0.85)
Vented: ~2.0–3.0 kWh per cycle (£0.65–£1.05)

Over a year (3–4 cycles/week), heat pumps often save £120–£200+ compared to condenser/vented—paying back the price difference in 2–4 years.

Key features to look for

Sensor drying (auto stop): Prevents overdrying and saves energy—essential.
Low‑temperature or wool/silk cycles: Protects delicates and activewear elastics.
Mixed load / cupboard‑dry / iron‑dry settings: Choose finish level for less ironing.
Reverse action drum: Reduces tangling and creases.
Anti‑crease tumble (post‑cycle): Intermittent tumbling keeps laundry fresh if you can’t unload immediately.
Fast cycle / time programs: Handy when you need items quickly.
Hygiene/Allergy program: Higher temps or longer phases to reduce allergens.
Drainage option (for condenser/heat pump): Plumb in to avoid emptying the tank.
Interior light: Sounds minor—actually very useful.
Filter access: Easy, front‑mounted lint filter cleans in seconds.
Heat pump self‑cleaning condenser: Keeps efficiency high with minimal effort.
Noise level: 62–69 dB is typical; anything under ~64 dB is pleasantly quiet.

Installation & placement

Ventilated space: Even condenser/heat pump models need airflow; avoid tiny, sealed cupboards.
Ambient temperature: Heat pumps work best in 10–35°C rooms; cold garages can lengthen cycles.
Stacking: Many 60 cm dryers stack on matching washers (use a proper stacking kit).
Worktop depth: Standard footprint is 60×60 cm; check door swing and hose clearances.

Smart features (useful, not gimmicky)

App control & notifications: See remaining time, get “empty filter” or “empty tank” alerts.
Fabric care assistants: Suggest the right program for the load.
Energy reports: Track consumption and adjust habits.

If you’ll never use the app, prioritise better sensors and drum design over Wi‑Fi.

Fabric care 101 (make clothes last longer)

Sort by fabric: Towels with towels, synthetics with synthetics.
Use low‑temp programs for activewear, elastane, and technical fabrics.
Don’t overfill: Leave a hand’s breadth at the top—air needs room to circulate.
Add dryer balls: Shorten cycles and reduce creasing naturally.
Remove promptly: Fold or hang warm to avoid ironing.
Skip the dryer: Air‑dry pure wool, silk, embellished garments, and waterproofs unless the care label says tumble safe.

Maintenance: keep efficiency high

Clean the lint filter every cycle (both filters if your machine has two).
Rinse condenser (on condenser dryers) monthly, unless self‑cleaning.
Heat pump: Clean fine filter and check evaporator area per manual.
Wipe door seal and drum; keep sensors clean (damp microfibre cloth).
Ensure drain hose (if plumbed) isn’t kinked.
Vacuum intake vents periodically.

Energy‑saving tips

Spin laundry well first: A 1400–1600 rpm spin on the washer saves big in the dryer.
Run full, not over‑stuffed loads; avoid lots of tiny cycles.
Use “iron‑dry” for items you’ll finish on a rack—saves time and energy.
Dry similar fabrics together; mixed loads extend cycles.
Warm, ventilated rooms speed drying and reduce cycle time.

What to spend (UK 2025 guide)

Budget (£230–£350): Vented or basic condenser, 7–8 kg, sensor dry.
Mid‑range (£380–£650): 8–9 kg condenser or entry heat pump, better sensors, anti‑crease.
Premium heat pump (£650–£1,100): 9–11 kg, A++/A+++, self‑cleaning condenser, quiet, smart features, wool/steam options.

If you dry weekly, a mid‑to‑premium heat pump is worth the investment for comfort, fabric care, and bills.

Safety notes

Always clean the lint filter—blocked filters are a fire risk and waste energy.
Don’t run overnight unattended if possible; if you do, ensure alarms work and filters are clean.
Keep softener‑soaked items and oily rags out of high‑heat cycles; use appropriate programs.

Tumble dryer vs heated airer vs dehumidifier

Heated airer: Cheap to buy, slow, can add moisture to the room; good for occasional items.
Dehumidifier + rack: Energy‑efficient, gentle, dries a roomful overnight; still slower than a dryer.
Tumble dryer: Fastest, most convenient, best for towels/bedding and regular family loads.

Many homes use a heat pump dryer for bulk loads and a dehumidifier rack for delicates.

Quick picks (by need)

Best for low bills: 9 kg A++/A+++ heat pump with sensor dry and plumb‑in drain.
Best small budget: 8 kg condenser with reliable sensors and reverse action drum.
Best for garages: Condenser with robust ambient tolerance (or keep garage above 10°C).
Quiet choice: Heat pump with <64 dB rating and balanced drum.
Family workhorse: 9–10 kg, large porthole, interior light, anti‑crease, mixed load program.

FAQs

Q: Are heat pump dryers really slower?
A: They can be, but newer models offer “speed” modes and better airflow. The energy savings usually outweigh a few extra minutes.

Q: Can I put a heat pump dryer in a cold garage?
A: It will work, but cycles may lengthen. If possible, keep the space above ~10°C or choose a model rated for lower ambient temperatures.

Q: Do I need to plumb a condenser/heat pump dryer?
A: No—you can use the water tank. Plumbing the drain is optional and convenient.

Q: Why do my clothes feel damp when the cycle ends?
A: You may have selected “iron‑dry” (intentional moisture), overfilled the drum, or the sensors are dirty. Try “cupboard‑dry” and clean the sensor strips.

Q: Will a tumble dryer shrink clothes?
A: High heat can. Choose low‑temp programs (heat pump excels here) and follow garment care labels.

Conclusion

The best tumble dryer for most UK homes in 2025 is a heat pump model: efficient, gentle, and increasingly quick. Pick the right drum size, insist on sensor drying and a decent anti‑crease, and keep filters clean. Whether you’re tackling family towels or rainy‑day school uniforms, the right dryer will save time, protect fabrics, and trim your energy bills for years to come.
