Email SupportMost oil tanks have a float gauge on top that shows your fuel level. Look at the dial or marker - it typically shows Empty, 1/4, 1/2, 3/4, and Full. Enter the percentage in HomeHeat (e.g., 50% for half full).
Predictions improve over time as HomeHeat learns your usage patterns. The more deliveries and readings you log, the better the estimates become. Weather data also affects accuracy - colder weather means faster consumption.
The estimate updates based on weather forecasts. If a cold snap is coming, your predicted consumption increases, which reduces days remaining. This is by design - it helps you plan ahead.
HomeHeat calculates "days remaining" until you reach a minimum safe level (typically 10-15%), not empty. This gives you buffer time to order fuel and prevents running your tank dry, which can damage your heating system.
