Abstract
A multiple boiler has at least two separate heating systems incorporated therein. Whereas boilers with two heating supplies have been known, they have been complicated systems that require heating to occur outside a water tank. The multiple boiler has an insulated water tank with a heater to heat the water in the tank without circulating water outside the tank. At least one circulating coil is located in the tank in heat exchange relationship with water in the tank.
