Calculation logic
What it calculates
Formula
Volume × a heat factor based on room-to-water difference, rounded up to 25 W.
Limits
Tank surface, lid, insulation, draughts and extreme room temperatures alter heat loss.
Next step
Use an independent thermometer and consider two smaller units where one failure would be serious.
