难的是自己买个拖回来，没pickup的话。还有就是搬，最好两个人搬。
但装的话，我一个人一边琢磨一边装，4小时都足够了。

Water runs hot and cold
Manufacturers of tankless water heaters are fond of touting their products'
ability to provide an endless amount of hot water. But inconsistent water
temperatures were a common complaint among our poll respondents. When you
turn on the faucet, tankless models feed in some cold water to gauge how big
a temperature rise is needed. If there's cool water lingering in your pipes
, you'll receive a momentary "cold-water sandwich" between the old and new
hot water. And a tankless water heater's burner might not ignite when you
try to get just a trickle of hot water for, say, shaving.
Nor do tankless water heaters deliver hot water instantaneously. It takes
time to heat the water to the target temperature, and just like storage
water heaters, any cold water in the pipes needs to be pushed out. And
tankless models' electric controls mean you'll also lose hot water during a
power outage.
Up-front costs are high
The tankless water heaters we tested cost $800 to $1,150, compared with $300
to $480 for the regular storage-tank types. Tankless models need electrical
outlets for their fan and electronics, upgraded gas pipes, and a new
ventilation system. That can bring average installation costs to $1,200,
compared with $300 for storage-tank models.
Tankless units might need more care
During our long-term testing, an indicator on the tankless model warned of
scale buildup. We paid $334 for special valves and a plumber to flush out
the water heater with vinegar. Many industry pros recommend that tankless
models be serviced once a year by a qualified technician. Calcium buildup
can decrease efficiency, restrict water flow, and damage tankless models.
Experts suggest installing a water softener if your water hardness is above
11 grains per gallon. Ignoring this advice can shorten your warranty.
Efficient storage models are pricey
We also tested the $1,400 Vertex, a high-efficiency storage water heater by
A.O. Smith. The manufacturer claims its installation costs are similar to a
regular storage model. But its high cost offsets much of the roughly $70 per
year the Vertex will save you. Instead, we recommend buying a conventional
storage water heater with a 9- or 12-year warranty. In previous tests, we
found that those models generally had thicker insulation, bigger burners or
larger heating elements, and better corrosion-fighting metal rods called
anodes.
