Hello, Jean Marc Beauchamp,

In my workshop I use a very classic humidifier that works with ultra sons.
It contents 20 liters, but it is not enough for more than 2 days in a very
dry period (winter) .
of course these systems are cheap, and I use mine for 3 years without any
problem but the regular cleaning of the vibrating element.
Filters for the water have to be changed once/year too.

The 100$ you evocate is for an automat system I guess, some are even higher
priced. They are very convenient, as you don't have to be there to put water
inside.

The cheapest automatic systems I've find where more around 1500$, so I
bought 15 ultra sonic humidifiers, had a good price and sell them to my
customers (I paid around $85 each).

In fact, if the aeration of the room is not too fast, after a few, the
moisture stabilize a bit and less water is needed.

Systems based on ultra sound are silent enough  and they work the same if
the room is hot or cold.
But eventually a very fine dust (a very few, that I could not notice in my
shop) is produce by the particles in water, and depose on the furniture
around the humidifier.

System based on steam works better when the room is cold and far less if it
is warm. make a little noise generally?

Other systems are based on natural evaporation,under an air flow and they
are noisy and not very efficient if the temp is cold.

The good place for a "floor humidifier" is not on the floor really, as the
moisture then will not be enough distributed in the place.

Mine is on a little table, but higher could be better, I use the water
coming from the climate control system, so I have distilled water at hand,
and the extra water (sometime) is driven outside . Sometime enough water
coming, sometime I may add some.

To protect the place from the humidity coming from outside, I have a special
fan that blows very dry air (25% approx.) from another room in the workshop
, so the shop is then under a slight higher pressure and humidity does not
come in.

I've find a very precise humidistat with an electric switch for controlling
this last system (a long tube with a few hairs inside that react to humidity
changes)

That seem as museum conditions, and a bit excessive, but in fact I was
obliged to act like this, as my workshop could not be enough isolated
despite the works we've done on the walls and the roof.

Ceci mis à part, je serai très interessé d'avoir des données d'optimisation
ou générales sur un Steinway B , N.Y. (1961) accelerated action, et votre
expereince en ce domaine me passionne. Merci pour votre généreuse
proposition.

Hope that helps.

  Hello you all,

  I am the head pianotech at the Faculty of Music of the University of
Montréal (french speaking University). They will soon begin to build me a
new shop which will have 700 square feet. I want to find a good humidifier
for that room, a floor model. There is no humidifier system in that old
building. I would like to find one around $ 1000,00. Anyone could suggest me
something in that range.

  Also I would like to exchange info about the Stanwood metrology. I use
this metrology since 1995 to rebuild grand piano action. I cumulated over
the years datas. I would like to share, exchange and discuss with other
fellows who use that system.

  I hope my english is OK.

  Thanking you in advance,

  Jean-Marc Beauchamp RPT
