Households that use natural gas spend about $950 a year on heating costs, while the price tag for those who rely on oil to keep their houses and apartments cozy is a whopping $2,115 annually [source: National Energy Assistance Directors Association]. It requires more energy to maintain a temperature than it does to reduce the temperature for a period and then turn it back up. While in vertical installations, the flow up position can perform slightly better due to the positive effect of gravity. There are also cases where the discharge temperature is more than 3 degrees of saturation temperature. Heat naturally moves to places where it's cold. Thermocouple Response Time Study for Steam Temperature Control Temperaturforskjellen mellom utlpet fra kompressoren og kjlemediets kondenseringstemperatur vil gi tilgjengelig mengde overheting. That's not to say that your sunny apartment needs to be converted into an igloo.
