Adding a boiler to an 86 PT

[Pete Masterson]

My coach came with an AquaHot unit as standard. I note that it has its own small Racor fuel filter. The burner nozzle has a very fine hole to turn the diesel into a mist to burn efficiently. Any debris that gets to the nozzle has a high chance of clogging it. There is a second fuel filter in the fuel line after the Racor. So, do consider adding appropriate fuel filters (and regularly replace the elements as necessary).

To me, this is most useful for hot water and engine heating rather 

than coach heating.  I really must say that I think not giving the 

option of propane for water heat is the biggest error BB made in 

these coaches.

Here's  what I did.  Mounted the boiler in the front curb side 

compartment, tapped the generator for the fuel supply.  Using T-

connectors I accessed the supply and return water lines wired it up 

and flipped the switch.  I replaced the auxillary circulation pump in 

the rear of the coach with a higher capacity unit.  I doubt this 

upgrade is cheaper to operate as compared to propane but it adds an 

additional heat source and preheats the engine faster than the 

electric engine heater.

A word on fuel supply, it's always a good idea to isolate the 

supply to each fuel using component with a dedicated check valve.  

Back flow and air in the lines are your enemy.
