Rumford 1000H

In addition to the features of the original Renaissance, the 1000H offers a heat recovery system.

The Rumford 1000H comes with a gravity vent system designed to increase efficiency and potentially heat additional rooms.

Gravity vents are simply ducts that use hot air’s natural tendency to rise to re-distribute heat. The ducts can be installed in the same room as the fireplace, into an adjacent room or up to 15 feet up to a second floor. There is no power required in order for the gravity vents to operate. We also offer an optional blower that can increase the air flow through the gravity vents. The optional blower boosts efficiency and helps to move warm air throughout the home.

With the door closed and the optional blower installed the efficiency of the Renaissance Rumford 1000 H approaches 50%. The efficiency of a traditional open fireplace is often somewhere between 0% and 10%, and can actually be negative. They achieve negative efficiency by having more heat drawn out of the room with the fireplace than is being created by the fire. Fireboxes that are made the traditional way with a deep square back do very little to push heat into the home. The Rumford firebox design allows for optimal heat output in any log configuration.

*It is very important to note that, although there is considerable heat radiated from the front opening of the RR1000H with the door open, the net efficiency of all fireplaces with the door open is very low because of the huge amount of heated air which flows up the chimney. To achieve maximum output and efficiency, the Renaissance Rumford 1000H must be operated with the door closed.
