As with all heating sources, care must be taken to ensure that the ambient temperature is kept as close to 20☌ as possible and the piano should not become warm to the touch. Provided the temperature and humidity are correctly regulated, this need not cause any problems. Underfloor heating is becoming more common, especially in newer houses. These are available from Steinway Hall, or from your local piano dealer. To avoid damage to wooden floors castor cups can be placed under the wheels. As a general rule if the piano feels warm to the touch from any heating source (including direct sunlight) it should be moved. The piano should not be placed close to a window, an outside door, a radiator or other heating source. If humidity needs to be controlled artificially we recommend using a humidifier or dehumidifier to regulate the humidity of the room rather than localising it in the piano with a climate control system. Large swings in humidity should be avoided and it is advisable to purchase a thermometer and hygrometer to monitor conditions. The ideal conditions are a constant temperature of 20☌ and humidity between 45% and 70%. In the short term, this will keep the tuning and regulation stable and in the longer term will avoid more serious problems such as cracks in the soundboard. It is important to keep the piano at a constant temperature and humidity level. A piano is largely made of wood and felt which, as natural materials, react to changes in temperature and humidity.
