All figures at a glance
How this ranking is made
This selection is put together automatically from the 160 models in our database that meet the criteria above. We only include models whose figures for the ranking are known: without those values a model cannot be compared fairly, so it drops out. The list is recalculated with every data update, so the order can change as soon as manufacturers or registers publish new values.
The order follows a single feature: Water heating efficiency ηwh (highest first). Where values are equal, the alphabetical order of brand and model decides. The other features are shown as extra columns in the table so you can see how a model does on other points; a model at the top for this one feature can be weaker elsewhere.
The reasoning for each place is derived automatically from the same data. We name the features on which the model is in the best quarter of this selection, functions that not every model has, and a weaker point if the model falls in the bottom quarter on it. The line ‘Choose this model if …’ links the most heavily weighted strength to a situation where it matters. This is not a test and not personal advice: the installation, your home and the price also decide what works best for you.
The values come from EPREL; the product page shows the source of every value. How we collect and check the data →
