Most reliable heating and ventilation products
Our annual reliability survey reveals which heating and ventilation products are most reliable.
Our members have once again told us if their appliances and devices – from expensive cooktops to cheap-as-chips heaters – are reliable and satisfying to own.
About our survey
We asked our members about products they’d bought new in the last ten years. We wanted to know the brand, the year it was bought and whether it had ever needed repair. We also asked respondents if they were satisfied with their product. Our thanks to all who participated.
We only analyse brands that got 30 or more responses in a category. For each brand, we calculate our reliability score as a weighted percentage of its products that have never needed repair.
Where we haven’t re-surveyed a particular product, we’ve included the reliability data from surveys conducted between 2017 and 2019.
