Methodology & sources
Specs from the manufacturer, prices left to the retailer, nothing invented.
Sources
- Boiler architecture, PID, pre-infusion and machine type come from manufacturer spec sheets and product documentation.
- We store only a coarse, stable price tier — never a live price (those change weekly; check the retailer).
What we never do
- No invented "scores" — groupings reflect boiler/PID/price facts, not opinions.
- No sponsored placements.
- Dated "last verified" on every page.
