Description
- This application claims the benefit of provisional patent application No. 61/206,038 filed Jan. 27, 2009 by the present inventor.

- 1. Field:
- This application relates to residential or commercial hot air and/or water heating or furnaces.
- 2. Prior Art:
- Fireplaces, stoves, inserts and other hearth appliances are one of the most popular features in American homes. In fact, half of all U.S. households (55 million) have at least one fireplace or freestanding stove. Fireplaces rank among the top three features desired by new home buyers, after outdoor porches and upgraded kitchens, according to the National Association of Home Builders (NAHB).
- The strength of any fireplace is the look and feel of an open fire. No insert or stove has yet been developed which can match the esthetic value of an open brick wood burning fireplace. Forty Eight percent of all new homes built today have at least one fireplace.
- The critical weakness to any wood burning brick fireplace is inefficiency. It is well known that brick fireplaces are inefficient. A majority of heat from any brick fireplace is lost up the chimney. Further any wood burning brick fireplace will typically only heat the area immediately adjacent to the fire itself.
- One combined and complicated chimney and fireplace design has attempted to incorporate a heat collecting mechanism in a chimney and fireplace structure. U.S. Pat. No. 4,043,313 to Sherman discloses a complicated design for the construction of an entire fireplace and chimney structure.
- Thus if this design (U.S. Pat. No. 4,043,313) is used an entirely new and expensive structure, chimney and or fireplace, or significant and expensive alteration to the chimney or fireplace is required. Being relatively cumbersome and complicated Sherman's design cannot be easily installed. Also, by attempting to collect heat at levels far above the firebox less heat is collected. Sherman's design relies upon convection or the naturally occurring and slowly rising volume of hot air to provide heat, thereby limiting the amount or volume of hot air and the control of its introduction into the heating system. Sherman's design provides a cumbersome and incomplete integration system and fails to provide a simple control mechanism or thermostatic element to control the switching functions between the design and the primary home heating system.
- The American Chimney Furnace is easily installed pre or post construction into a fireplace or smokestack chimney structure. Heated air rising from the fire, typically wasted energy, contacts the top, bottom and both the interior and exterior walls of the open ended prefabricated assembly, thereby heating the air contained within. The embodiment has one intake and one exit vent both connected to the pre existing or newly constructed heating system and fully integrated thereto via the American Chimney Integration System. Untreated air is forced or drawn through the intake valve, passes through the hollow interiors walls of the embodiment and exits as heated clean air through the exit vent. The heated, clean air is then delivered directly to the plenum or furnace of the preexisting primary heating system for distribution throughout the premises.
- Thus, several advantages of the embodiment are as follows: The embodiment significantly increases the efficiency of residential fireplaces, chimneys or commercial smokestacks. Ease of installation and integration. The embodiment can be manufactured in a variety of standard shapes and sizes engineered to fit a majority of existing chimneys including residential and industrial chimneys worldwide. The embodiment provides a secondary heating system. The embodiment allows fireplaces to be enjoyed as designed and built with no obtrusive or cumbersome inserts, stoves, significant alterations or esthetic changes. The embodiment significantly reduces heating and energy costs. The embodiment distributes heat and energy to an entire premises or significantly larger portions thereof. The embodiment reduces wasted energy. The embodiment reduces dependence on foreign oil and gas. The embodiment reduces greenhouse gases from burning fossil fuels for heat or energy. The embodiment increases the use of renewable energy resources. The embodiment has low maintenance requirements and costs. The embodiment may be used to provide higher temperatures to
habitable spaces 80, 90 or 100 degrees, with no additional cost, as turning your thermostat to 80, 90 or 100 while burning wood or other combustible fuel in a fireplace at a roughly constant rate, will not result in wasted energy or heat, by burning additional wood or other fuel. The embodiment allows the user to simply start a fire without further thought as to switching between the embodiment and the primary home heating system, as that function is automatically controlled by the combination of the embodiment, working with the temperature sensor and the thermostat. - In accordance with one embodiment the American Chimney Furnace is an open ended stand alone durable heating system or furnace installed into a fireplace typically just above the firebox and/or in smoke chamber and/or chimney system, collecting and providing heat.

Reference Numeral 22—FIG. 2 ). - When the interior of the embodiment's hollow walls achieve a sufficient temperature from the rising hot air from the fire, as determined by the interior temperature sensor (
Reference Numeral 10—FIG. 1 ), the Thermostat (Reference Numeral 22—FIG. 2 ) starts the Air Pump (Reference Numeral 38—FIG. 3)—thereby forcing or drawing air through the air supply pipe into the embodiment, the clean air is heated within the hollow walls of the embodiment and exits as hot air via the heat output, directly to the primary heating system (Reference Numeral 300—FIG. 3 ). The thermostat (Reference Numeral 22—FIG. 2 ) simultaneously shuts off the gas, oil, electric or other primary furnace, therefore, heating the habitable spaces solely by means of the embodiment in conjunction with the wood burning or other fire. - Cool or untreated air is forced through the embodiment from the air supply (
