Both steam boilers and hot water boilers (also called hydronic boilers) involve the heating of water and creation of steam through the burning of fuel. That heated steam or water circulates through a radiant system to heat your home. Boilers are generally more energy efficient than furnaces, usually using less fuel to provide the desired temperature. That means potentially lower energy costs. Since boilers don't blow air, they don't spread dust or allergens or require filter maintenance. They also don't dry out the air as much as blown hot air would.
