Some time ago, I asked a question about a climate control system install in a "box" for a piano at a small symphony. There were helpful posts but no pictures. I forgot to take pictures on the install date, but recently took these. I hope they will be helpful for future searches.
The box is made of 1" plywood and has been there long before I got there. No insulation--just wood. The piano is a Yamaha C7.
The system is for a vertical piano with an additional heater bar. I built the little box from scrap wood, then painted it. The box has sides on it, and was built so that all the parts would stay in the correct place. In other words, the humidifier would be in its correct position relative to the humidistat and dehumidifier bar, similar to the way a vertical system is installed. (I don't think it really matters too very much inside the box, but that was the thought I had.) The dehumidifier bar is supported by clips that are screwed into the top of the box...the same ones we use to suspend the bar.
Someone had suggested a fan to help circulate air inside the box. I thought that was a good idea. The fan was around $15-20 on Amazon. It plugs into an extension cord and is always running.
I stapled plastic sheeting to the inside walls of the box, and also made some 1" vent holes at the top of the box. The vent holes probably are not necessary with no insulation, but I figured it might be a good idea.
I bought plastic tubing from Lowes, and ran it to the top of the box so it would be easy to fill from the outside. The control panel is also outside the box near the fill tube.
The box is at the back of the stage of this old auditorium, and is on the outside wall. The auditorium is not cooled or heated very consistently. According to the hygrometer that I left on a beam, it does a pretty good job of maintaining consistent RH.
Anyone have suggestions for a new title for this thread? The search feature here is not very helpful and if there are better terms, I can edit the title.
