Is it OK to over-size an Econoburn?

0

Prior to selecting boiler size, a heat loss calculation for the system is critical. Under-sizing a boiler can result in a system unable to maintain an indoor temperature of 70 degrees; plus, a too-small boiler will shorten burn times. On the other hand, over-sizing a boiler slightly is acceptable and will lengthen burn times on systems without thermal storage. Please note, however, at some point during the heating season, any boiler without thermal storage will be oversized for its application. An over-sized boiler will likely spend more time idling and less time gasifying. Excessive idling will reduce the efficiency and cause creosote to build up in the combustion chamber and heat exchanger. To maximize efficiency and reduce creosote, only fill the firebox enough to maintain a fire until the next refueling time is feasible. This will force the boiler into gasification more often by reducing the portion of the heat load satisfied by the upper chamber alone.
