The current heat pump warning UK applies to certain tumble dryers with integrated heat pumps sold by Haier under eight different brands, not to domestic heat pumps used to heat a house. Affected appliances pose a serious fire hazard, as an internal short circuit may cause them to smoke or catch fire. Owners should discontinue affected models, and manufacturers should arrange modifications.
This guide explains the affected brands, model checks, immediate safety steps and updated repair programme before covering safe everyday dryer use. Once the appliance is determined to be safe, running costs and/or timing can be discussed. If households are now thinking about broader electricity management, solar and battery storage strategies can now be part of their long-term plans.
Understanding the Current Heat Pump Warning in the UK
The current heat pump warning UK is a product-safety issue and does not concern all heat pumps, but only certain integrated heat pump tumble dryers from the company Haier. It does not apply to every kind of heat pump dryer, and it has nothing to do with domestic heat pumps for space heating. Before taking any action, owners should first determine if their specific appliance is covered.
Scope of the Heat Pump Warning UK and the Appliances It Actually Affects
The ongoing heat pump warning in the UK applies to some of the integrated heat pump tumble dryers from the brands Baumatic, Candy, Caple, Haier, Hoover, Iberna, Lamona and Montpellier. The OPSS has identified that the products are a serious fire hazard and has developed a modification programme. Where specific models and product identifiers are listed, this does not necessarily mean that all dryers from this brand are impacted.
Serious Fire Risk Behind the Government Warning Heat Pump Dryers Notice
The government warning heat pump dryers notice states that during normal use, the dryer could have an internal short circuit. This fault can cause the tumble dryer to catch fire and pose a significant fire hazard. OPSS also says that impacted products are not compliant with the Electrical Equipment (Safety) Regulations 2016. The fault may result from normal use and owners of known problem appliances should not depend on shortened operating times but should follow the recommended stop use and repair instructions.
Distinction Between Affected Tumble Dryers and Domestic Heating Heat Pumps
A home-heating heat pump and a heat pump tumble dryer operate on similar heat transfer principles, but have entirely different functions. This warning only applies to particular tumble dryers and not to air or ground-source heaters that are used to heat homes. Readers who want to learn about individual heating technology can look at how domestic heat pumps work. This safety alert should not therefore be seen as a blanket warning against residential heat-pump heating systems.
Brands and Models Covered by the Heat Pump Tumble Dryer Warning
The warning is not for all dryers made by the affected brands, but only for specific products. That's why owners should know the specific model and serial number before assuming the appliance is safe or affected. OPSS has individual Product Safety Reports for each brand in the corrective-action programme.
Eight Brands Included in the Current Heat Pump Tumble Dryer Safety Warning
The heat pump tumble dryer safety warning applies to certain models of eight different brands: Baumatic, Candy, Caple, Haier, Hoover, Iberna, Lamona and Montpellier. Haier made integrated heat pump dryers under different retailer brands. But even if the appliance has one of these brand names, owners must confirm the exact product details.
Model and Serial Numbers Used to Identify Affected Appliances
The heat pump warning UK applies to specific dryers, depending on their model and serial number. Affected products include specific models such as Haier HDBI H7A2TBEX-80 and Caple TDi4000/TDi4001, as well as selected models from Hoover, Candy, Lamona, and Montpellier, each with different identifiers. Owners must transcribe the model and serial numbers from the appliance label and check them against the official list; don't rely on how the appliance looks.
Checking an Appliance Against the Official OPSS and Manufacturer Safety Lists
The best way is to refer to the appliance via the official OPSS Product Safety Reports or Haier's product-safety service. Anyone whose model is listed, or who does not know their model, is advised to contact the manufacturer, OPSS. The existing corrective-action page also contains the helpline 0808 178 0516. Owners should rely on these official checks, not unofficial recall lists or marketplace information.
Immediate Action for Owners of an Affected Tumble Dryer
If a dryer is determined to be impacted, safety is first, not energy consumption or convenience. OPSS recommends that owners immediately stop using the appliance, isolate it in a safe location, and contact the manufacturer to arrange the approved modification.
Stopping Use Immediately After Confirming the Heat Pump Tumble Dryer Warning
Owners should immediately stop using the model if it is covered by the heat pump tumble dryer warning. Until the required current modification is performed, the appliance shall not be used again. Continual or intermittent use, or use under watch, is not a workaround, as the fire risk can occur during normal operation.
Switching Off and Unplugging an Affected Appliance Where It Is Safe to Do So
If the plug is accessible, OPSS recommends that its owners turn off and unplug the affected dryer. This deters the appliance from being used while repairs are made. Don't disassemble the machine or attempt electrical repairs. Do not move or interfere with the appliance unnecessarily; if access is unsafe or difficult, follow the manufacturer's guidance.
Contacting the Manufacturer to Arrange the Required Safety Modification
The affected owners are asked to contact the manufacturer and register the appliance for the approved safety modification. Haier's programme applies to the affected brands, and the helpline is 0808 178 0516 for owners who need help or are unsure if their dryer is covered. The appliance should not be used until it has been repaired to the last approved repair.
Repair Program and Previous Safety Modifications
The previous corrective action did not fully address the safety concern and is why the current repair program is being implemented. OPSS considered the original modification and asked Haier to stop that program and resume repairs only after an updated solution had been evaluated. Owners who have had their dryers repaired in the past should therefore verify which modification their dryer had.
Development of the Government Warning Heat Pump Dryers Corrective-Action Programme
The government warning heat pump dryers program started after the OPSS found that more than 100,000 heat pump dryers posed a serious fire risk. In May 2025, Product Safety Reports were issued, and Haier began recalling the affected dryers. OPSS then studied the failure and the effectiveness of the proposed repair, and ultimately had to modify the original corrective action to allow the rest of the program to proceed.
Earlier Repairs and the Reason an Updated Modification Became Necessary
OPSS suspended Haier's first repair program, saying it was not convinced that the changes to affected dryers made them safe. In August 2025, the owners of the machines fixed before 1 August received a warning that there may be a fire hazard and that they should not use the machines. Haier subsequently made a second modification, which OPSS reviewed before it could proceed with the repair program again.
Confirming That the Latest Approved Repair Has Been Completed Before Reuse
Owners should check that the dryer has the latest approved modification before use. According to OPSS, any appliance with the "J7" marking on the rating plate has been modified and doesn't need further work. Items labelled "HM1" (or not modified at all) are still affected and should NOT be used until the most recent repair is finished.
Safe Use of Heat Pump Tumble Dryers Outside the Affected Recall
The current safety alert is not intended as a warning against all heat pump tumble dryers. Appliances not affected by model ranges may be used as per the manufacturer's instructions. Safety, efficiency, and long life of appliances still depend on regular maintenance, proper installation, and prudent operating practices.
Why the Heat Pump Warning Does Not Apply to Every Heat Pump Tumble Dryer
This heat pump warning applies only to models and serial numbers included in the Haier corrective-action programme. The fact that the same drying technology is used does not automatically mean that other heat pump tumble dryers are affected. Owners should therefore check their appliance details for safety information and not assume that all models are unsafe. Dryers that are not affected should be used as directed by the manufacturer and/or product-specific safety information.
Filter Cleaning and Appliance Maintenance for Safe Everyday Operation
Heat pump tumble dryers require good airflow, and you should clean filters and other user-maintainable parts as often as the manufacturer recommends. Lint build-up can reduce drying performance and increase drying time. Regularly checking seals, vents, and accessible filters also helps detect problems early. Household energy monitors can compare the energy costs of running a dryer with maintenance and operating practices.
Installation, Ventilation and Manufacturer Instructions for Unaffected or Repaired Dryers
Even if the heat pump is unaffected or properly repaired, installation should still follow the manufacturer's guidelines. Do not interfere with or modify clearances, ventilation, electrical supply, or drainage arrangements. Owners should avoid overloading the drum and investigate any unusual odours, sounds, or recurring fault codes. If the recalled dryer has been repaired, confirm the most recent approved modification before making any of these normal-use recommendations.
Home Energy Planning After Appliance Safety Is Resolved
Once a tumble dryer has been identified as unaffected, or as having the most current approved modification, it is time for energy scheduling to come into play. At that time, households can consider the time of use, the amount of electricity consumed, and whether that electricity can be generated using solar generation and/or battery storage without impacting safe operating guidance.
Scheduling a Safe Heat Pump Tumble Dryer Around Solar Generation and Household Demand
A safe heat pump tumble dryer can also be used when it is most useful, when rooftop solar is producing a useful electricity output, so as to minimise the electricity drawn from the grid. If solar generation is not available, households with appropriate tariffs may want to look at when electricity is cheapest and use smart appliances then. Always remember safety first: scheduling only applies to dryers that are not affected or repaired properly and shall not be a substitute for the manufacturer's operating instructions.
EcoFlow STREAM 5000 for New Solar and Battery Storage Planning
EcoFlow STREAM 5000 can generate solar power at the same time and store it for later use by household appliances. This can help support the use of a safe tumble dryer when solar production is at its highest and reduce some electricity imports later on.
EcoFlow STREAM AC 5000 for Existing Solar Homes Adding Battery Storage
For households already equipped with rooftop PV, EcoFlow STREAM AC 5000 provides storage, allowing them to keep more of their PV system's generation for later use. This retrofit solution can enable flexible appliance scheduling while keeping the existing solar system.
Conclusion
The current heat pump warning in the UK does not apply to all heat pump domestic heaters or heat pump tumble dryers; it applies only to a limited range of integrated heat pump tumble dryers covered by the Haier corrective-action programme. Owners of affected models should refrain from using it until the latest approved repair has been completed, verify the model and modification, and only use the appliance if modifications are not applicable.
Once the appliance's safety is fully resolved, the focus can shift to electricity timing and solar self-consumption. By storing daytime solar power for later use in household appliances, EcoFlow STREAM 5000 can help fill gaps in the power grid for new solar-and-battery planning.
FAQs
Is Every Haier or Hoover Heat Pump Tumble Dryer Included in the Heat Pump Warning UK?
No, the heat pump warning UK only covers particular models and product identifiers in the Haier corrective-action programme. If you have a Haier or Hoover heat pump dryer, it doesn't automatically mean it's affected. Owners should verify the specific model and serial details with the official OPSS safety reports, or contact the manufacturer if in doubt.
Can a Second-Hand Owner Still Arrange a Repair for an Affected Heat Pump Tumble Dryer?
Yes, the safety programme is about affected appliances, not their purchasers.
Please see the model and serial number first.
Check the model and serial number first.
Contact Haier if the appliance is included.
Keep the dryer unused while the required modification is arranged.
Affected households should contact the manufacturer to have the appliance made safe, OPSS says.
Can an Affected Tumble Dryer Be Used Occasionally While Waiting for the Repair?
No, occasional, supervised or short-duration use of an affected heat pump tumble dryer while waiting for modification is not recommended. Because normal use of the appliance may pose a serious fire risk, OPSS has recommended that affected owners stop using it. Do not use the dryer until the existing approved corrective action is finished.
Can Home Battery Storage Make an Affected Heat Pump Tumble Dryer Safe to Use?
No, home battery storage will not fix a tumble dryer safety defect.
Battery power does not remove the electrical fault.
Solar electricity does not make an affected dryer safer.
The approved manufacturer modification is still required.
Changes of energy source should never be viewed as an alternative to the OPSS safety instructions. Do not use the affected appliance until it is made safe.
Can Battery Storage Use Daytime Solar Energy to Run a Safe Tumble Dryer Later?
Yes, if a dryer is confirmed to be unaffected or has been modified to be compatible, it can store excess solar energy generated during the day and use it later that day or at night. This can help shift peak solar use and increase solar energy consumption on-site. The number of drying cycles that can realistically be supplied from stored energy will depend on the battery capacity, solar surplus and dryer consumption.
