The effect of the environment

A piano does not like to be too hot or too cold. A constant 18 to 21 degrees Celsius (65 - 70 degrees Fahrenheit) is ideal.

Central heating systems can dry the air, and draw moisture from the wooden components of the piano. When the heating is switched off at night the humidity rises, and conversely, as it is switched on in the morning, the humidity drops. These changes in relative humidity cause the wood alternately to shrink and expand, causing tuning instability. Ideally, you should try to keep your piano within 45 - 60 per cent relative humidity.

Keep the piano away from windows if possible. Do not place your piano near a radiator or other heat source, or on an inside wall where there is a radiator in the next room backing onto the piano, resulting in heat being transmitted through the wall. These locations, where constant excessive or fluctuating heat causes low or changing relative humidity, are often responsible for tuning instability and other serious problems, such as loose tuning pins, split soundboard and disruption of regulation. A separate music room is ideal, but a dining room is often suitable, as this will usually be maintained at a lower temperature, and have a reasonably constant humidity level. Should you feel that your piano is in an unsuitable environment you should consider buying either a humidifier to counteract excess dryness, or a dehumidifier for excess dampness.

If in doubt ask for advice. That's what I'm here for,
