A friend gave me some mint, and didn't mention what type it is. How can I tell if it's spearmint, peppermint, apple mint, lemon mint, or some other variety? I googled some pictures, but quite frankly, all the pictures look very similar -- four leaves growing from the center which a textured leaf and a rich, green colour.
A water source air-conditioner or heat pump is a variation of a traditional air source heat pump. The explanation that follows first describes how a cooling-only water source air-conditioner. works. A description of a heat pump (heating and cooling) will follow.
A heat pump is an electric powered piece of equipment that both heats and cools your home. In the summer, a heat pump is no different than an air conditioner. In the winter a heat pump operates in reverse and heats the indoors. Heat pumps need auxiliary heat (electric heat or gas furnace) to help them when it is very cold (below 42 degrees in the North Georgia Mountains) or when the thermostat is moved more than 2 - 3 degrees at a time.
