Posted By: iObsessed How to Control Humidity w/o Dampp-Chaser - 06/16/14 09:35 PM
I'm curious as to whether it is possible to set up a humidity system (e.g. humidifier and/or dehumidifier, depending on the needs) in lieu of the Dampp-Chaser. It is a great system, but I heard that it isolates the piano, while in an ideal world, you want the whole room to be affected so that your piano will be ideally humidity-controlled. Also, I'm not really a fan of having holes drilled in my soundboard for the system. I think the ideal humidity range is like 40 to 50 percent, right?

I also see people pour this capful of solution their jug of water when they refill the Dampp-Chaser. What is that made of, and what does that do?

Oh, and BTW, drilling holes in the soundboard will lessen the quality of the piano's tones, will it?
Dampp-Chasers are attached via tiny holes in the huge beams, NOT the soundboard. There are metal bars fitted under the soundboard to hold the water tank (held by gravity) and a thick, plastic flashing to protect the board from any water damage. The only screws are to hold the little plastic brackets for the heat bars and hose and those go into the case and beams.
I use a small room dehumidifier in my piano shop; it consistently maintains about 55% RH.

I do get tired of emptying the fill bucket though... smile

Oh the solution is simply Lysol. It's to keep the humidity pads from getting gross. I recommend using DC's actual solution, as I'm sure it's a certain concentration for their system and they give you a ton of it when you order the tank.
iObsessed,

The best way to keep the temp and humidity controlled is by means of a full house HVAC system with a humidifier installed into the system. Another method is to control the humidity in the room in which the piano is located using humidifiers and dehumidifiers as appropriate to the season.

Many of us choose the full home approach with the addition of a D-C system as a final "tuning", as it were.

First of all, let me emphasize that the soundboard is not, in any way, touched or altered by the installation. For a grand piano, all of the components are attached under the piano and in an upright, they are inside the cabinet. For full information, there is a link to the Piano Life Saver System (D-C) on the side of this page.

The treatment fluid that you mention is to keep any mold and algae from growing in the tank and tube and to make sure the water is electrically conductive. The D-C system monitors whether the tank needs to be filled by means of a low electrical current sent through the reservoir. As it is a heat/evaporative system, any minerals in the water supply will start to build up on the evaporator pad as 'lime' deposits. To guard against this, and increase efficiency, using distilled water is recommended. However, distilled water doesn't conduct electricity so the D-C fluid is added to serve two purposes.
Thanks for the replies.

I'm curious as to how you knew this...

April Air offers whole house humidity control systems. Humidex is excellent for high humidity areas.

I looked up the chemical on the back of the bottle and it's the same stuff that's in Lysol. Also, I know the rest of it because I have a Dampp-Chaser.
Could anyone furnish a picture of the metal bars mentioned above? and where they are placed?

Oh yea, if they drill holes into the piano, where do they drill?
iObsessed,

Here is the link to their website. You will find the information you are looking for there.

When I was shopping for a D-C PianoLifesaver system for my grand, I contacted several distributors. One said he needed to drill a hole in my soundboard, to route the fill tube up under the lid and make it easy to fill. No one was going to deface my new soundboard in my fully rebuilt piano! I scratched that installer off my list.

The more common installation method, and which I selected, is to keep the fill hose clipped to the beams, below the soundboard. I merely reach under the rim to unclip the tube end, and then fill the system with the watering "can."

Tone Depth, you did the right thing in shopping elsewhere. There are idiots everywhere installing everything incorrectly! Drilling through a soundboard is not standard installation procedure.

Yeah I can't imagine the sense in routing the fill tube up through the soundboard in a grand. I don't have a D-C system, but if there's any chance that water could dribble down the outside of the tube when filling it, the soundboard is the last place I would want it to end up. It's just not worth the supposed convenience.

To be fair though, drilling a hole in the soundboard is standard installation procedure for vertical pianos, and is used to pass the electrical cords.

At risk of asking a stupid question, if I have sited my piano in its final location I could do worse than having a floor mounted power outlet under the piano so I would have no trailing cords going to the wall?
@Voltara a very loud WHAT? I would NEVER, EVER, EVER let anybody drill a hole in the soundboard, are these guys out of their mind?

Do you really need a dampp chaser there? Bulgaria doesn't have a very extreme climate does it?

I am just asking the same thing of my friend, Veneta Neynska, a professional pianist who lives in Bulgaria.

The temperature range is fairly pronounced from maybe -15 in the winter to 35 in the summer. (Roughly zero to mid nineties Fahrenheit) Humidity I am not so sure about. Anyway I shall be guided by what Veneta says.

Whilst typing that I got a response from Veneta. She said not to bother. So I won't!
