At 72 inches wide by 84 inches long, the California king mattress is perfect for those who want more length in the bed. The California king is 4 inches narrower than a king size mattress, but it is 4 inches longer. This bed size still gives each sleeper 6 inches more sleeping width than a queen size bed.
An induction heater is a key piece of equipment used in all forms of induction heating. Typically an induction heater operates at either medium frequency (MF) or radio frequency (RF) ranges. Induction heating is a non contact method of heating a conductive body by utilising a strong magnetic field.
Heat pumps are like central air conditioners, except that the cycle can be reversed and used for heating during the winter months. (Heat pumps are described in more detail in the heating section.) With a central air conditioner, the same duct system is used with a furnace for forced warm-air heating. In fact, the central air conditioner typically uses the furnace fan to distribute air to the ducts.
