Floor heat

[Frisbeekev]

Was running the heat in my rv (floor ducted heat) off of a house plug. Not all the registers were blowing hot air. Do I need to be plugged into 30 amp to have all registers to blow heat, or is it broken, or another issue?

As long as the fan is turning fast enough to allow the gas to ignite, you don’t need to be plugged into a higher amp service. If you have warm air out some and cool air out other registers ( outlets) I would suspect either a blockage of some sort, or maybe the duct has come loose from the heater exchange box.

Locate your heater. You may have to remove the screws holding in a grill to inspect things. The ducts are inserted into holes and rotated, not common but I have seen some come undone or not put on properly. If all the ducts are attached, then you may have kinks or debris in the duct work.

Another issue I have seen is smaller diameter ducts used for longer runs and such. Air like water will take the path of least resistance, and it’s not uncommon to get good flow from the 3” duct and lousy/no flow from the 1 1/2” ducts. Be careful about covering outlets to redirect the heat, as it may cause the furnace to overheat, tripping the high limit switch and shutting down.

+1 for Chuckster57...

Your profile doesn't state the age of your camper or if this is a new problem that wasn't there before. If it's a new camper, my advise is to make it the dealers problem. As Chuckster stated, it's not unheard of for the ductwork to be in need of reconnection.

Good Luck,

It's a brand new camper. Worked before. Will check the lines, then get it to the dealer if needed. Thanks

This is what we discovered when we pulled out the register on our new 5th wheel.

That is just sad. Even if a worker goes to lunch early you need to fix that when you get back. You just cant close that up. Ugh poor quality control

That is just wrong.

Looks like someone went to war in that space.

If it worked before then that damage is new. Could be the factory did a lousy install that fell apart after use which is what it looks like, but I would suggest you look closely for any evidence of rodents. Those little critters can tear up anything and it would be frustrating to fix it and have a repeat performance by a mouse.

Needs to be better staffing of quality control.

if it worked before, then likely something new is either blocking the duct, or if flexible ducting it may have come disconnect or crushed.

I would check the connections at the furnace first, if you have rigid in floor duct I would make the seal between the duct and furnace better, factories tend to just set the furnace over the hole in the floor! That creates a very poor seal! This is when a roll of good foil duct tape is your best friend. I used to seal all unused covers on our furnace, and all floor connections.

This looks like loading damage, seeing the carpet in the picture looks like a 5er basement. To me looks like somebody shoved something in to the space and knocked the register box loose and tore it duct. Might think about devising protection for that register box!

rhagfo,
My picture wasn't the best and it rotated when uploading, this is not the basement. This is the floor vent beside the kitchen island and dining room slide. I pulled the vent cover off and then took out the register box only to find the ducting was all tore up. We fixed it.

Was it rodent damage?

Yes! The dirty rats that assembled it, that don't give a rat's a## how it's put together.
