Source sentences:
text: 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.
text: Condensing boilers also achieve high efficiencies so if the unit has an ErP A rating then you’ll know that it’s condensing.
