OK Bob, thanks for clearing that up, 0.29 GPM makes a lot more sense than
29 GPM.

The only catch is that the bucket must be straight sided. An ordinary
bucket that is flared out at the top will over estimate the rainfall because
the water will be deeper at the bottom of the bucket than it should be. The
flared out top catches more rain than the bottom can hold and keep the

I don't know if its an apocryphal story, but I heard that in response to the
outcry over killing whales with explosive harpoons, Japanese whalers tried
electrocuting them, but when the large dose of electricity necessary to kill a
whale hit it, the ship also was electrified to the same degree.
I like to use pipe dope instead of the tape. The tape can cause a problem
if you start to wrap in the wrong direction and it can also cover some of
the opening if it is wrapped a little too far.

That's how they measure it.; An inch in the bucket equals an inch of rainfall.

by anything like runoff from a roof or gutters. I'm sure there could be lots

Clear water is a pretty high resistance, so you'd need a more
complex circuit to measure the change in resistance when both your
high resistance finger and the water arrived at your chosen level.
Also, water will tend to wick up things that are placed into it,
so there is a loss of accuracy that wa
Sounds right to me.
The more area you expose to the rain, the more accurately you will record the
rain fall. Presumably you could collect the water from your roof provided you
know the area it covers and can do the math. Don't use the area of a sloped
roof though, only the area it covers. There

I'm not denying your numbers or even your experience since you have been

They have had tankless water heaters a lot longer than that. It is nearly 40

stated are the least expensive. A unit with a water supply rate
from .29 gal to 8.5 gallon a minute is available for 1400 bucks. Some
of these units for houses go for over 3 grand with a 7 year warranty if
wanted.
I would say that "not perfected" is a bit strong since folks in Europe
have been using tankless water heaters for a couple of decades now.

Further to your experience Dan, they have so called intelligent units which

When I was looking at tankless water heaters, these were a single heater
in the basement to heat the water for the entire house. So, the pipe run
to the fixture would be the same distance as with my regular hot water
tank, and thus no instant hot water at the fixture and no water savings.

One inch of rain is in deed one cubic inch on the ground.
A bucket with a surface opening and vertical sides of course will accumulate a
hundred cubic inches of water when an inch of rain falls. A very narrow tue

To increase accuracy
I would think weight would come into this calculation.

It's a highly scientific form of measuring. At the airport they have a bucket
with a float in it. The float raises and lowers on a scale that shows how much
rain has collected in the bucket during a period of rain. If interested in
making the same measurements on your own you'll have to buy
I still won't know how much rain that is. I don't think an inch of rain
constitutes a cubic inch of water per every square inch of surface. So how
do they measure an inch of rain?
