Abstract
With small, generally residential heating systems, it is common to use a single forced-air furnace for heating and cooling of all levels. The basement is normally provided with supply air from the furnace, which is distributed to the space from ceiling diffusers. The result is that the area where the furnace thermostat is located (normally the main floor) is comfortable but the basement is warm at ceiling level and uncomfortably cool at floor level. The invention that we have devised provides a means of effectively heating a basement (or other) floor, wall or ceiling slab using a conventional forced air furnace as the heat source.
Description
Disclosure This invention relates to an apparatus that uses a forced-air furnace as a heat source to heat the fluid circulating through an in-slab radiant heating system.
It is common, when utilizing an in-slab hot water heating system, to use a boiler as the heat source for the fluid. Boiler systems are more complex to design, operate and maintain than forced-air furnaces.
We have found that by using this invention to provide heated fluid from a furnace, a radiant floor heating system can be incorporated, resulting in a warm comfortable basement without incurring the expense and complexity of adding a boiler.
In the drawing which illustrates the embodiments of the invention, A hot water coil is placed in the supply air duct from the furnace. Plastic tubing, specifically designed for radiant floor heating applications, is cast, either into the floor slab (new construction) or is cast into a new concrete slurry topping over an existing slab.
A heating medium (water, treated water or glycol) is pumped through the coil then through the plastic piping cast into the floor slab.
In a typical single or two story house, the furnace will be controlled by a thermostat located on the main floor occupied space. When the thermostat calls for heating, the furnace burner will ignite and the furnace will supply heated air. The heated air will first pass through the new coif. Water will be pumped through the coil and will in turn be heated. The heated water will circulate through the floor slab piping network and return to the pump.
The result is that when the furnace is on, some of the heat will be drawn by the coif, slightly reducing the temperature of the heated air being supplied to the space. The furnace will run longer to satisfy the space heating requirements because of the lower hot air temperature and the basement slab will become warm, thereby creating a comfortable environment in the basement.
To stop the basement from overheating, the pump is also controlled by a thermostat, which is located in the basement. When the basement reaches a comfortable temperature, the pump will stop, and the system will operate like a conventional furnace.

Claims (2)
1. A fluid coil / pump / thermostat assembly that uses a forced air furnace as a heat source to heat fluid for a radiant floor system.
2. A fluid coil / pump / thermostat assembly that, during the cooling season, draws cool fluid from imbedded floor slab piping and transfers cooling to the supply air stream of a forced air furnace.
