Apparatus, systems and methods of using 70 CFM ventilation fans with heaters for bathrooms having depressibly engageable and depressibly releaseable light covers. The novel ventilation fans and heaters can be mounted to structure in ceilings and inside walls with telescoping suspension brackets that are affixed directly to separate sides of the housing to support the housing against joists and structural supports behind the ceiling. Adjustable louvers on the grill cover allow for outgoing heated air to travel in a different direction into a space from the incoming air travelling into the housing. Plastic type housings around blower wheels reduce undesirable noise effects. The light covers can be easily opened and closed by using depressible engageable fasteners, and depressible release fasteners.

1. A ventilation fan for bathrooms, comprising: a housing having top, side walls and open bottom, and an exhaust outlet through one of the sidewalls of the housing, the open bottom adapted to be mounted adjacent to an opening in a ceiling;a first blower wheel and a first motor for running the first blower wheel, both mounted inside of the housing, the first blower wheel being rotatable in a plane perpendicular to the top of the housing, wherein the first blower wheel has a volute and an outlet;a plenum removably attached to the outlet of the first blower wheel for redirecting air from the first blower wheel in a substantially vertical direction;a heating element positioned inside the plenum adjacent to the outlet of the first blower wheel;a second blower wheel and a second motor for running the second blower wheel, both mounted inside of the housing, the second blower wheel being rotatable in a plane perpendicular to the top of the housing, the second blower wheel adjacent to the exhaust outlet in the housing;a grill cover covering the open bottom of the housing having a first longitudinal end and a second longitudinal end, the grill cover having a first grill portion on the first longitudinal end and a second grill portion on the second longitudinal end separate from the first grill portion, the first grill portion having an outlet for allowing all outgoing air from the first blower wheel which has been heated by the heating element to be passed out of the housing, the second grill portion having an inlet for allowing all incoming air to be pulled into the housing by at least one of the first blower wheel and the second blower wheel; anda light in the grill cover between the first grill portion and the second grill portion with a removable lens cover for covering the light. 2. The ventilation exhaust fan of claim 1, wherein the motor is an approximately 70 (seventy) CFM (cubic feet per minute) generating motor. 3. The ventilating exhaust fan of claim 1, further comprising: a receptacle box for the motor located outside of the housing against an outer wall of the housing for providing power connections to the motor and blower and light. 4. The ventilating exhaust fan of claim 1, further comprising: a first elongated side telescoping bracket directly mounted along one side wall of the housing; anda second elongated side telescoping bracket directly mounted along an opposite side wall of the housing. 5. The ventilating exhaust fan of claim 1, further comprising: female sockets in the grill cover behind the lens cover; andmale prongs extending below the lens cover for being inserted into the female sockets, wherein the lens cover is attached to and released from the grill cover by the male prongs and female sockets. 6. The ventilating exhaust fan of claim 5, further comprising: moveable inner parts inside of the sockets, wherein the springs are positioned beneath the inner parts; andbendable arms are attached to the inner parts, wherein initially depressing the male prongs into sockets causes the bendable arms to hook about enlarged heads on the male prongs to lock the lens cover in place, and subsequently depressing the male prongs causes the springs to push to out the inner parts to release the lens cover. 7. The ventilating exhaust fan of claim 1, further comprising: a plastic enclosure for completely surrounding at least one of the first blower wheel and the second blower wheel to guide the air in a controlled path to prevent excess noise and provide maximum performance to exhaust or heat the air, so that air is trapped once it enters at least one of the first blower wheel and the second blower wheel, and guided to the outlet without any corners for the air to be stuck. 8. The ventilating exhaust fan of claim 1, wherein at least one of the first grill portion and the second grill portion includes adjustable louvers so as to direct at least one of the incoming air and the outgoing heated air in separate directions. 9. The ventilation fan of claim 1, wherein the first blower wheel and the second blower wheel are simultaneously switchable to both run at one time. 10. The ventilation fan of claim 1, wherein the first blower wheel and the second blower wheel are separately switchable to run at different times. 11. A ventilation fan for bathrooms, comprising: a housing having top, side walls and open bottom adaptable to be mounted adjacent to an opening in a ceiling;a first blower wheel and a first motor for running the first blower wheel, both mounted inside of the housing, the first blower wheel having a volute and an outlet;a plenum removably attached to the outlet of the first blower wheel for redirecting air in a substantially vertical direction;a heating element inside the plenum adjacent to the outlet of the first blower wheel;a second blower wheel and a second motor for running the second blower wheel both mounted inside of the housing, and side by side with the first blower wheel and the first motor, both the first blower wheel and the second blower wheel each rotatable in a vertical plane relative to the bottom of the housing;a grill cover covering the open bottom of the housing having a first longitudinal end and a second longitudinal end, the grill cover having a first grill portion on the first longitudinal end for allowing all outgoing heated air from the first blower wheel to be exhausted outward therefrom, the grill cover having a second grill portion on the second longitudinal end for allowing all incoming air to be pulled inside of the housing by at least one of the first blower wheel and the second blower wheel; anda light in the grill cover. 12. The ventilation exhaust fan of claim 11, wherein the motor is an approximately 70 (seventy) CFM (cubic feet per minute) generating motor. 13. The ventilating exhaust fan of claim 11, further comprising: plastic enclosures that completely surround at least one of the first blower wheel and the second blower wheel which helps guide the air in a controlled path to prevent excess noise and provide maximum performance to exhaust or heat the air, so that air is trapped once it enters the blower wheel and guided to the outlet without any corners for the air to be stuck. 14. The ventilating exhaust fan of claim 11, wherein at least one of the first grill portion and the second grill portion includes adjustable louvers so as to direct at least one of the incoming air and the outgoing heated air in separate direction. 15. The ventilating exhaust fan of claim 11, wherein the first blower wheel and the second blower wheel are simultaneously switchable to both run at one time. 16.
