wishing to leave a gap in coverage, I’m continuing the
discussion of on-demand hot water with the assistance of
Jean Cunningham of Philadelphia says:
have an oil-fired hot-water heating system with what is
called a ‘summer-winter hookup’ — the oil burner
also heats our water, and we have no separate water
heater or water tank.
had this system with two different oil burners for 30
years and no complaints, no problems at all, and
unlimited hot water any time.
don’t know if it even matters, but frequently in the
summer after we’ve taken showers, we just switch off
the system at the top of the basement steps until the
next day, when we need hot water again, thinking maybe
we’re saving a bit of oil, although I’m not sure if
we are or how much."
Michelle Flack of Egg Harbor:
three weeks ago, we had installed a Rinnai tankless
1989, when the house was built, we replaced the water
heater two times, and this third time we made the
decision to go tankless.
tankless cost is very high, $3,000, plus the added
charge for a grounded outlet to be put in by the
have very hard well water, and even though we use a
softener, our washer still becomes clogged with
minerals, as well as (our) faucets, which also caused
the corrosion of our third water heater. We anticipate
that we will need to ‘flush’ the tankless heater at
least once a year.
only drawback, thus far, is lack of pressure will not
trigger the hot water to come on.
have a handheld showerhead in our master bath. If we do
not run the hot water at a slow-trickle in the bathroom
sink, once we adjust the shower temperature downward,
the sensor will shut off the water heater.
this time, I would wholeheartedly recommend a tankless
above a standard tank heater, but once again, facing
mineral buildup in the future, we may or may not be
regretting this decision."
