If you are buying a new tumble dryer in Bulgaria in 2026, the practical choice is now mainly between different heat-pump models. Since 1 July 2025, EU requirements have allowed only in-scope new household tumble dryers using this technology to be placed on the market. You may still encounter an older model that entered the market before the change, but do not compare appliances by the energy-class letter alone.
If you already own a working condenser dryer with an electric resistance heater, the question is different: will the electricity saving be large enough to justify buying a replacement now? The answer depends on the two specific models, your annual number of cycles and your electricity price—not on a universal percentage.
First: a heat-pump dryer is also a condenser dryer
The two names are often presented as opposites, but technically they are not. A heat-pump dryer also removes moisture from clothes and condenses it. The difference is how the machine heats and reuses the air.
- An older condenser dryer with a resistance heater heats the air electrically. A cycle can be shorter, but energy consumption is higher.
- A heat-pump dryer uses a refrigeration cycle and recirculates heat. This reduces energy use, although the eco programme can take longer.
“Faster” therefore does not automatically mean “more efficient,” and “heat pump” does not mean that every model performs equally well.
What the current EU label shows
Since 1 July 2025, tumble dryers use an A-to-G energy scale. The old A+++–D classes cannot be compared letter for letter with the new ones. Look at the numbers and the test conditions.
- Label value: kWh per 100 cycles · How it helps: Lets you estimate annual electricity use from your own number of cycles.
- Label value: Capacity in kg · How it helps: Should match your normal laundry load, not just the washing machine's maximum.
- Label value: Eco-programme duration · How it helps: Shows the efficiency-versus-time trade-off at full load.
- Label value: Condensation-efficiency class · How it helps: Shows how effectively moisture is collected as water instead of remaining in the room.
- Label value: Noise level and class · How it helps: Matter when the appliance is close to a living room or bedroom.
The label values are based on the eco programme. A short, intensive or specialist programme may use a different amount of energy and take a different amount of time.
How to estimate whether replacement pays back
A common mistake is to take a marketing savings claim and turn it directly into a payback period. Use the data for the two actual appliances instead.
1. Find the old dryer's consumption in its manual or product sheet. If it is stated for one cycle, record it as kWh/cycle. 2. Divide the new label's kWh per 100 cycles by 100. 3. Multiply each appliance's consumption by your real annual number of cycles. 4. Multiply the difference by your final household electricity price. 5. Divide the total purchase and installation cost by the expected annual electricity saving.
The formula is:
simple energy-only payback = replacement cost ÷ annual electricity saving
This is a guide, not a complete financial appraisal. It excludes future repairs, the old appliance's residual value, financing, changes in electricity prices and the environmental impact of manufacturing a new machine.
If the old dryer is used rarely and remains reliable, replacement for electricity savings alone may take a long time to pay back. With several cycles each week, the difference accumulates more quickly. Use your own numbers.
When a longer programme matters
Heat-pump models can dry more slowly, particularly in eco mode. That matters if you run several loads in sequence or depend on a quick laundry turnaround.
Do not compare only the shortest advertised programme. Check the full-load eco duration on the label and the conditions and maximum load for quick programmes in the manual. Smaller loads, well-spun laundry and clean filters can affect real cycle time.
What else to check before buying
- Filters and heat exchanger: check which parts the user must clean and how often. “Self-cleaning” does not mean maintenance-free.
- Water drainage: the tank must be emptied, or the dryer needs a suitable drain connection.
- Size and installation: check the full depth with the door and hoses, and use an approved stacking kit if the dryer will sit above a washing machine.
- Capacity: a large drum adds little value if you normally dry small loads.
- Noise: compare dB and the noise class, not only descriptions such as “quiet.”
- Repair and parts: check the warranty, service network and availability of important parts. From 1 January 2027, the EU label must also include an A–E repairability class. In 2026 it may appear voluntarily, but it is not yet mandatory.
The decision in three scenarios
You are buying a new dryer
Compare current heat-pump models by kWh per 100 cycles, duration, condensation, noise, capacity and maintenance. Do not pay for excess capacity or features you will not use.
The old machine works and you dry infrequently
Run the calculation first. If the annual saving is small, keeping the appliance, maintaining its filters and planning replacement when a significant repair is needed can be reasonable.
You dry frequently or face an expensive repair
The lower consumption of a heat-pump model then carries more weight. Compare the repair quote with the cost of a new appliance and calculate the saving from your real cycle count. Also check whether the longer eco programme fits your routine.
The right answer is not automatically “replace the old dryer” or “use it until it fails.” For a new purchase, heat-pump technology is the practical standard. For a working older appliance, the answer comes from the label, your usage and the actual replacement cost.
