Espar heater starting to fail

The fuel pump should make a ticking noise each time it pumps, that will let you know if it is working right or now. It will not start pumping when you first turn the heater on, there is a start sequence where the glow plug will preheat before it starts sending in any fuel.

 

ThermoKing has the Espar parts

places to order online much cheaper though. MUCH cheaper.

 

You got to replace the glow plug screen they get carbon packed. Everything else is a waste of time and money. should be done each year. Go on you tube there are video's on how to maintain these units.

 

if you can't get it going eventually, the Chinese have copied these heaters and you can get one for about $150 I had ordered one to heat my little shed but when I got this truck it actually did not have a bunk heater in it so I pulled that one and installed it. it's rated at 5kw and does fine, some cases the heater will use the existing holes from the factory unit. If you go that route feel free to PM me or reply here and I can give you more info

 

Is there a brand or name for what you bought?

 

Jet fuel is mostly kerosene.

 

You are welcome to have a device below your bunk that has a flame and an unlimited amount of diesel fuel under pressure operating made by an unknown company.
When it burns your truck to the ground because you wanted to save a few bucks, let me know how that works out. That is assuming you got out alive.

 

It won't burn the truck down, a friend has tested a couple dozen of these heaters as part of his job and they are pretty safe if installed right.

The one failure point common is the control unit.

These things all use the same exact design and the same circuitry with the same safety system as the Espar.

The fuel pump is very low pressure, enough to pull the fuel out and put it into a very small orifice in the heater.
