I took out the heating channels when I foamed insulated the bus.
I now can't get heat out of the back floor vents. from the bus heat, only from the front vents.
Are the ones in the back only return vents and is there a way to get heat to the back of the bus from the orginal bus heat
thanks carl mci 9 |

the return air to the heat/ac is the louvers in the ramp that goes past the 1st 4 rows of seats.... the blow side is the stainless duct work on each sidewall, right next to the floor... the duct comes up thru the floor about the 4th row of seats....if you removed this stainless cover.. it sticks out about 4", and is about 10" tall, then you took out the ductwork....if you look close at the exterior siding of your coach body, you can see a louvered panel.... about 10-12' back from the front, this is the fresh air inlet for your a/c--heater.... |

Hello carl mci9.
In my MC8, there are air returns on each side in the rear, just aft of the last baggage bay bulkhead, in the area of the rear wheels. The duct work back there has a seperator built onto the wall: lower portion is grated for return air from the floor, upper portion is part of the continuous flow from the front. This return makes it's way forward under the centre aisle, below the floor and above the "utilities" which you can access from the baggage bays.
In effect, think MC7 sunken aisle with a cover on it.
Otherwise, in original service, it would have been fairly impossible to get anyone's feet warm towards the rear of the bus in winter/sub-arctic conditions.
I believe that the HVAC systems in the '8 and '9 are similiar in execution.
You may be able to re-direct the HVAC output to run your conditioned air "backwards" down the return, since some heat, is better than no heat.
You may need to temporarily remove the heat exchanger and AC evaporator or lift the floor to get at the appropriate place to divide the return from the rear and the intake mentioned in the last post found in the aisle ramp/step behind the driver.
With the use of some directional control, you should be able to blow the output out along the floor in the rear, instead of up the wall as in the stock configuration, to good effect for a conversion. After all, you don't have to provide cooling and heating for 47 souls anymore, half of whom were leaning against the outer walls and windows!
happy coaching!

Sorry, to clarify:
In stock configuration, there are HVAC intakes located in the aisle ramp/step alongside the first few rows of passenger seats, and an intake on either side of the floor, inside the duct work, just ahead of and above the rear wheels, which runs forward under the aisle, and joins with the intake found in the ramp/step, then goes down into the HVAC cavity found behind the big piece of plywood in the forward end of the front baggage bay bulkhead.
The HVAC output is found coming up through the floor, inside the duct work, one to a side, in close proximity to the front intakes, so alongside row two or three of passenger seats.
Removing the ductwork will also cut off any HVAC supply to the vents in the top of the driver's side switch panel. The defroster air circulation is unrelated to the main coach HVAC in relation to duct removal.
Hope this clears things a bit.
happy coaching!
