With each cycle, pre- and post-purge air flow removes heat from the boiler and sends it out the stack. The energy loss can be reduced by using a high turndown burner (10:1), which keeps the boiler on even at low firing rates.
If the pressure is below 1 bar, then your boiler is likely to have low pressure. What to do if your boiler has low pressure Once you know that the drop in pressure hasn’t been caused by a leak, or a leak has been fixed, you can re-pressurise your boiler to bring it back to the normal level (1 bar) – check the instructions that came with your boiler to find out the boiler pressure
