Swipe across on a small screen.
Each bar puts a published or calculated figure on our fixed 0 to 5 visual scale. These are not official product ratings, customer review stars or an overall recommendation. Scores are rounded to one decimal and stay between 0 and 5. Search and selection do not change them.
Tank size 400 litres is the 5-point reference. This is the published tank volume, not an efficiency rating or a promise of how many showers. Larger tanks need more space. Household use and reheating speed also matter.
Parts warranty 7 years of main-product parts cover is the 5-point reference. Free registration requirements are shown in Specs; paid extensions are excluded. Accessories, labour and installation may have separate terms. Battery usage limits can end cover sooner; heat-pump component and tank terms are listed separately.
Noise More bars means quieter: 35 dB is the 5-point reference and 65 dB is zero. The bar uses the maker- or seller-published number; its source and original measurement conditions are in Specs. Seller figures are labelled separately. This visual scale is not a certification or a measure of how many times louder one unit sounds.
Reheating speed More bars means faster reheating. 150 litres per hour is the 5-point reference. Calculated rates use the same 45°C rise in water temperature. Colder air can slow reheating; makers do not all use the same air-temperature test. Separately labelled maker estimates retain their published basis. Original tests and assumptions are in Specs.
See note means the available source does not give a comparable figure. The note explains what the brand publishes, and Specs includes the exact source and conditions.
Larger capacity is not automatically a better match. Choose equipment sized for your home and needs.
