Any details..?

They have Pex line on underside of trailer and use a Wabasco heaters to heat the coolant.

After using mine a few times it’s pretty slick. Was about -5 out and I set mine on high and left it on for about two hours, was too hot in my trailer. Mounted my battery tender and a 12 volt fan( same as the ones in a school bus) Moves the air around hood a d dries the floor out pretty quick.

How long will a battery run these? Need 2 batteries or 1 good ?

Easily over night with heater and fan running !

I believe an enclosed battery must be vented to the outside...

Only if you sleep in it!

What kind of fan? Where did you mount it?

Never been around floor heat so wondering if you lose heated air by opening rear door, then close it, does it recover quickly enough to change clothes inside?

I replaced my Rv battery today. Added a 6 amp battery minder and a fan.

After the battery died while the heater was running it did not want to start.

Today I took it apart. Cleaned out all the carbon and crap from poor burning from trying to restart it with a crappy battery
It took 45 minutes to remove, clean ,reinstall and turn on. Very easy.

So important thing to remember is a a good fully charged deep cycle battery. With 10 amp start up. 1 amp to run and 10 amp shut down.

Reason I added a 6 amp battery minder is running a fan , charging phone and heater running. When Inrun the generator it will charge battery while still running everything.

Just purchased a cube with a espar diesel heater.. it was not used in 7 years and did not need much to get working again other than a good battery voltage and fuel..

It runs to the truck cooling and heating system as well to keep truck warm as well cube, he has a fan heat exchanger inside cube to extract heat for cube..

Only ran it a few hrs so far with warmer weather but wanted to know if only one heater is needed or should I set up a second to warm a 14x8 cube on colder days.. it is fully insulated thou..

It is tied in to a 5 gallon boat fuel tank but plan to plum it to truck fuel tank later if it has a lift pump, pretty impressive to work after that many years sitting

Doesn't seem to be a issue,they are also running forced air heaters as well for gloves&boots.

Learned why my heater would flood at 3 or 4 hours

The hertz pump pulse and fan speed came set for sea level

I lowed pulse hertz and increased fan speed.

Ran today for 7 hours while I worked on the door.

Zero issues

That is pump speed and fan speed

I set mine to 2500 feet. So far runs way better than original seal level setting

What kind of piping you using for ventilation, normal PVC?
