Heat While Driving

Looking for some advice here...

I removed the stock Heater from the front of the bus as well as the two main coolant lines running from the back where the engine is (I did this almost immediately in the renovation)

Now,I'm wishing I left those in and had heat while driving!

I have found "Kickspace" or "Toe-Kick" heaters as a potential option but am not sure if I could run new lines tapped into the coolant system.

If there are better or more obvious options I'd love to hear them.

When the bus is parked we will have a Dometic Ac/Heat Pump in the middle of the bus as well as two MaxxFan's in the ceiling. Plan is stay where temps are mild but I'm currently in Maryland and potentially heading South this January. Seems like the cold is something I need to plan for

My little bus never had a heater so I used a trans cooler and a few computer fans to make up a slim line heater that tucks nicely into the toe board between the driver's and passenger's seat. I put an electric solenoid valve in the heater line to allow me to turn off the flow of hot coolant to the core. Little darling blows out a LOT of heat. Jack

just reconnect the original bus heater / defrost.. thats the best and cheapest way to kjeep that biog windshield clear too.. if you threw away the original bus defrost system.. shame on you but hit ab us junkyard and replace it for cheap... if tyou are crusing in the winter you need defrost / defog as well as heat.. that computer fan is neat for a small bus but not gonna defrost the windshield esp when the snow gets on the wipers.. Bus heaters are rather large BTU.. driving into the wind is chilly in an RE where you dont have the engine heat in front of you..



if you want the fancy expensive stuff proair llc makes osme nice heaters and also heater, A/C combos that work well.. I used these in my DEV bus as I wanted dashboard A/C, i kept the original right-side bus heaters but gutted and rebuilt my driver heat box.. I stay OK warm in the winter, but i'll be hooking up another heater for this winter as even with 50,000 BTU of heat in near zero temps I was chilled..

Haha, yes, shame on me!

I think a Salvage yard may be a decent way to go to. If that proves difficult based on where I'm at I may have to go a different route.

After market defrost option???

Any thoughts on Diesel Heat System?

you can use multiple units and deidcate them to purpose.. a single hot rod heater like a summit or jegs heater can be used for each purpose.. a ducted heater for each side of thew windshield and then one for driver heat.. 3 smaller consumer style units can work.. just make sure when you hide them to look nice that you make it so the ycan still be serviced.. to clean the coils, replace the motor ,etc..



something like this can be mounted center for your defrosters..

other options here..



https://www.jegs.com/p/JEGS/JEGS-Hot...97917/10002/-1


install electric solenoid 3/4" valves at the rear of the bus in the engine bay..

run 1 inch lines up to the front... use 1 inch to 5/8" T fittings to each heater.
run your heaters in PARALLEL.



this should giuve you great heat up front.. the blower CFM is a little low for a bg windshield but with directable vents it can be made to clear the parts you need.. installing heated wiper blades is a big help if you plan to drive in the snow and ice at all

The original heater had probably NEVER had the coils cleaned and had an opening from the outside into the box and no air filter at all. I don't even know if it works for sure, but I have cleaned it up. I can seal the opening to the outside (it's a crack where the edges of the side wasn't lined up properly before being screwed together). I don't really understand where the air intake is on it. I hate to pay $400 for a new driver heater. Does anyone have pictures of an old one that has been cleaned up and modified a bit to have an air filter and be cleanable?
