  • The Difference Between Boilers And Water Heaters

    Jun 08, 2009 · There are two common options for using a home's boiler for water heating. The most common is referred to as a "tankless coil." This is a relatively small heat exchanger that fits into a gas- or oil-fired boiler. These are popular for people with hot-water baseboard heat because they're inexpensive options or retrofits for standard boilers.Learn More
