How we choose and score
Each heater becomes a normalised data sheet: we take its specifications from the Amazon page and the manufacturer and translate them into a fixed set of fields with their units, so two models can really be compared.
The seven scores
From that data we calculate seven scores from 0 to 10, always with the same criteria:
- Heat output: watts relative to the recommended area.
- Speed: how quickly the heat is felt depending on the technology.
- Efficiency: thermostat quality, power adjustment and thermal inertia.
- Quietness: noise level and whether there is a fan.
- Safety: tip-over and overheat protection and moisture resistance.
- Ease of use: remote, connectivity, display and weight.
- Value: all of the above relative to the indicative price.
They are editorial judgements, not manufacturer data, and they are recalculated when the catalogue changes so they stay comparable with one another.
What we don't do
We don't invent specifications: if a figure is missing, the page shows a dash. We don't present a price as “current” without a date. We don't change a score because a product pays a better fee.
