The burner has to be running at around 20%, the return water needs to be below 100 F depending on the make of the boiler. A better estimate is 84% - 92% seasonal efficiency. This is still much better than the tradional boiler efficiency of ~82 % for new non-condensing boilers and 55% - 65% for older boilers.

Best Boiler Buying Guide - Consumer Reports

Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted.This condensed vapour leaves the system in liquid form, via a drain.

What is a Sludge? - Definition from Corrosionpedia

because it reduces the heat-transfer capabilities of the boiler, resulting in poor fuel-to-steam efficiency and possible pressure vessel damage. Sludge is removed by mud or bottom blowdown. During the surface blowdown process, a controlled amount of boiler water containing high dissolved solids concentrations is discharged into the sewer.
