road heat

[jlaney]

hello
i have removed the heating coil on my prevost . also killed the a/c unit
is it worth the effort to run engine water up to the dash for the small amount of heat it will put out. also thinking on using the  water lines to run my refrigenent lines  up to a remote blower unit. which i will mount under the kitchen cabinets. the water lines look to be 1 3/8 " AND

I think I would keep it for the defrosters if nothing else.

sorry
must have hit wrong key.
the old hot water copper will make a good conduit to run the a/c lines from the compressor that is mounted on the aux gear box that runs the radiator fan.
any help will be great.  j.t

Hi JT,

I would certinly keep the dash heat, not only for what busnut 104 said but, also for heat.

The front of the bus is also a big heat loss while driveing not to mention air leaks...

Good Luck

thanks
do you think the engine water pump will circulate enough water to the front of bus. since i have taken the circulating pump out of the  system.
thanks j.t

Hi JT,

I certinly think so... Your only talkin a small coil. My bus doesn't have a seprate circulator and both coils heat just fine for me.

JT,
I think Nick is right! I don't know what kinda bus you have, but heat is one thing that is hardly ever complained about on most buses! It's usually too HOT, even in the winter! LOL! FWIW   BK

 Yes  keep it, you will be glad that you did, it will cook you out of there, well at lease ours will. It will keep the front of the bus warm while you are driving.

You never know when you will need the heat, keep it, you will be glad you did. I had to install a heat exchanger in the front of our Eagle because the old one expired due to age. You can never have too much heat or a/c in my opinion. You can shut either down if needed.

Happy Trails,

Paul

A windscreen defroster would be regarded as essential safety equipment so you will need something to keep the screen clear.

I removed the A/C and heat system from under the floor.  I kept the heater coil which is about 6 ft by 14" and about 3" thick.  I mounted it inside the bus under the hanging closet with two 14" elec radiator fans to power it.  The big heat exchanger is on a ball valve I can turn off during summer.  In the winter, just having the ball valve open creates alot of heat where the fans rarely run.  But when they do, I can count to 10 after I hear them turn on and feel heat in the front of the bus- and they are not ducted-just dumps into the hallway.  When  I run the big heater, I also turn on the booster water pump.  I also kept the front defroster, also with its' own ball valve (which works fine without the booster water pump running).  I cut a hole in the wood covering in the dash I built so I can feel if the pipes are hot or not.  I can tell you that just with the vent open and the movement of the bus, just the front defroster keeps most of the bus warm enough where the big heater doesn't come on.  When it gets below 50 outside, then it does come on, but for only a couple of minutes at a time.  Since the big heater is so powerful and it hasn't been used much in the 12 years that it has been in, I'm think on taking it out and replacing it with two smaller auxiliary Red Dot heaters.  They are less than $300 each, and two would work well.  Then there will be enough space left over where I can install a Dometic truck A/C that is all in one of 7,000btu and have my quiet night time air conditioning.  Also will install another 10,000btu unit under the dinette/sofa for a quiet A/C for the front-just for night time use.  Will keep the 3 roof tops for during the day-but too noisy for sleeping.  Good Luck, TomC

I removed the A/C and Heat out of bay on my Prevost. The small defrost exhancer and fan is only good for the window defrost ... I had to add a cirulation pump that I hook up to the defrost blow fan, so when I turn on the fan the pump starts up.

You're going to have too add some other heat for the winter ... I installed a Hydro-Hot system and it's been well worth the price.

thanks
the heating coil looks to be a little  small to me also. i also still have the a/c coil mounted in the dash area. could i use it for cooling up front. the exspanion valve looks to be a f 22 refrigerant.  i have a webster blower coil that was used as  an aux air in  the rear of bus. i am trying to move it to  the front area . cutting holes in the stainless wall of the bays is a megger job.i had to just grind a hole for my gray water drain.
thanks jt.

my bus had the heat removed and that worked fine inAZ.  I'm in Ak and on my way back on Sunday.  I use a hair dryer to keep the windshield clear.  When it gets snowy the rv heaters keep the back of the bus warm but that windshield will give you fits.  KEEP THE FORNT HEATER AND DEFROST
