No, they don't. The majority of "boilers" merely heat hot water.

That's ONLY because they have an upper heat limiter installed on them
and/or by design won't reach steam level temps, otherwise, they'd be
making steam. They're used for 'hot water' only because they're much
more efficient at doing it, and much quicker. Many commercial
restaurants for example use a tankless water 'boiler' to provide hot
water to the devices in the store.

Aside from that, the term 'hot water heater' is still a bit of an
oxymoron if you're using it to describe the device in your house that
makes water hot for you. The incoming water isn't hot, obviously. Only
the outgoing water is. So, it can't very well be adding more heat to
something that's already 'hot' -- None of this takes into account homes
built with geothermal technologies. That's another ball of wax.
