A. Both electric and hydronic towel warmers are designed for in-home use. Electric towel warmers typically have very low energy consumption rates - many consume the same power as a standard light bulb (60 Watts). These models contain one of two types of low wattage elements: some use a dry element, while others use an element to heat mineral oil within the unit. Electric towel warmers are available as either hardwired or plug-in. Hardwired units will need to be integrated into the building's electrical system, while plug-in models simply plug in like any other appliance. Both types of electric towel warmers may be operated with an on/off switch or with a timer. Some of the larger electric units can provide enough heat to warm a room, though electric units are typically used in conjunction with another heat source to heat a room. Hydronic towel warmers simply utilize your hot water plumbing to produce heat by running the hot water through the towel warmer. This can be done one of two ways; by connecting to your home's hot water heater (open system), or to a specific hydronic heating system (closed system). In most cases the hydronic towel warmer is going to be the most efficient method (energy savings-wise) but can also be the most difficult for installation unless the installation is part of a complete remodel or new construction.
