Hi,

As I live in south east asia and due to the high humidity condition, It is quite necessary to use a piano heater 24/7. I was advised by the technician (who happens to be also the dealer who sold me the used piano) to install a second heater for better distribution and control of humidity within the cabinet. He tied the second heater on the hammer rest rail.

I had both heater functioned for about 2 years. Recently I engaged another established technician to tune my piano. I was surprise to be told that the second heater is not necessary and will damage the hammer action. I was further told that the heater had already caused some damages to actions, causing them to loosen due to the intensity of the heat. He advised that the heater should never be installed near the actions.

To play safe, I had the second heater removed now and with just 1 at the bottom of the cabinet.

As both technicians that I encounted have very extreme different opinion, I would like to seek the professional views in this forum on the correct method of placing the piano heater.

Thanks.

I am not expert, but I think one heater would be enough.

I also think that the heater at the action rail can actually cause damage to the action parts. Action parts (except Kawai) are made of wood, and swell under high humidity and can crack under low humidity. Thus, it's advisable to have the heater on to maintain the humidity at around 40-60%.

I think having the 2nd heater near the actions definitely make the humidity goes less than 40%, which is the optimum humidity for the piano.

I have never heard of 2nd heater, and I believe one heater is enough!

I assume that you mean a Dampp-Chaser heater bar? I have seen this done in the past to help alleviate problems with "sticky keys" due to tight action centers. I agree that it's probably a bad idea for the action, but I'd be even more concerned for the pinblock!

I guess in South East Asia we do not need the Dampp-Chaser mechanism. A heater bar is always sufficient to regulate our steady RH. I wonder why the dealer/tech wants ingenz to get another heater. Profit? A heater bar doesn't cost much... LOL

Hi Ingenz,

I am no expert either, but my gut instincts and common sense tells me that you should never ever install a heater bar anywhere inside the action area of a piano; you want to dehumidify the general area around the piano and not inside the piano (especially the action). In fact, I would go so far as to say the first used piano salesman/tech was incompetent and negligent to suggest or do such a thing. Of course, this is just my opinion and worth about what you paid for it \:D .

I would say you did the right thing removing the heater bar from inside the action.

Best regards,

Rickster

To begin with, what piano is it?
New or 2nd hand?
Brand? Year?
History?

2 heater at the bottom would be a good idea as a booster to reduce RH inside if you live near hill side .. hehe

Each heater bar is typically 25w 50~45degC, not infared 200degC type use for muscle ache healing.
I'm quite puzzle how the 2nd heater can cause harm to the action. Although the placement isn't so idea for convection current, it could have been place there for tight bush healing in the first place.

You will have to give us more info for us to offer more accurate advise.

It's good that you seek opinion when you have doubts. We also like to know more about piano here. It may turn out to be an interesting thread... both are right, both are wrong, it could be the parts were already loose, or it was not loose but just scare you ??

cheers
