Please explain just how a condensing boiler is inherently quieter than a
non condenser. Similarly why it will warm up quicker. If you can manage to
before your lunchtime nap, or if still sober.


I didn't say that a condensing boiler is technically quieter then a
non-condensing. My last boiler was 28 years old and suffered from bad,
noisey kettling. In that respect a new boiler is quieter.

My new boiler warms up quicker presumably due to it firing up on all
cylinders in its modulating mode, which a lot of old boilers may not have.
Additionally, due to our system being modified with the new boiler
installation, our boiler warms up the house quicker.
