achieve the same comfort level, potentially reducing heating costs and expenses. Heaters increase the efficiency of a fireplace and hence the amount of heat that makes it from the fireplace out into the home. They work by having naturally convected and forced air funneled into the metal heat exchanger tubing that is then heated by the coals and/or fire. They draw in cold air from the floor and blow heated air back out into your home. This adds an element of conductive and

heating to the radiant heat typical of a basic fireplace. Grate heaters have been called many things: heatilator, hearth heater, fireplace blower, fireplace grate heater, Fireplace
Furnace, tubular grate heater, etc.

This tubular fireplace grate heater has a large surface area heat exchanger in a compact design, with a fan or blower (fans and blowers are not the same) to multiply the effect of natural convection.

This is a very basic tubular blower that sits under a grate and heats the air being pumped through it from the heat of the coals. It has a high rate of airflow but a small surface area.

The most critical elements of any tubular grate heater are: 1) Safety - construction material and method, design and features. 2) Material - quality steel that enhances
