An economizer serves a similar purpose to a feedwater heater, but is technically different as it does not use cycle steam for heating. In fossil-fuel plants, the economizer uses the lowest-temperature flue gas from the furnace to heat the water before it enters the boiler proper. This allows for the heat transfer between the furnace and the feedwater to occur across a smaller average

Of course, boilers can be used to heat potable water. But, when a boiler is being used as a heating system for a home, it relies on the thermostat to tell it when to start heating the water within its system. Most boilers are on a closed loop system, which means they don't continually use new water when sending the steam through the home
Sep 28, 2020 · Boilers are generally more expensive than furnaces and forced air heating systems. Because boilers hold water, if the tank leaks or a pipe bursts, you may have a mess on your hands. There's also the potential – though rare – of the water freezing and pipes bursting if the temp goes too low and there's a prolonged power outage.
