This is the simplest to add to an existing home and any existing heating system. A standalone cabinet, you simply find a convenient place to locate it in your room, and have it hard-wired by an electrician. Cabinets vary in size, but they’re generally only about 10” to 12” deep, so they integrate well into most homes' décor.
Proper sizing is critical and all brands do not provide the same amount of heat storage. Ensure that the units are strategically placed throughout the home to provide maximum comfort and savings. If the units are undersized, other heating sources in your home need to turn on to maintain a comfortable temperature and this will offset potential savings.
