Product family
Space heating, boilers and ventilation
Space heaters, solid fuel and packaged boilers, and ventilation units. How their energy test behaves, what Energy Mark reads early, and where each product is regulated.
The test
What the energy test looks like
Heating appliances are brought up to steady output, then measured at one or more load levels. Boilers and heaters can take hours to reach thermal equilibrium before the measurement period starts.
The early read
What Energy Mark reads
- Warm-up and approach to steady output
- Flue or outlet temperature trend
- Fuel or electrical input over time
- Ambient and return temperature
It predicts: Steady-state and seasonal efficiency, with a range. The certified result still comes from the full test.
