I agree with you re: overkill not needed.
My question for this thread is do these Suburban heaters have only one cycle or two? I want / need (our furnace is dead....read: I am tired of trying to get it to cycle on...it does not) to replace ours and I really would rather buy a two cycle (or more?) blower type heater.
Any suggestions? We have a 1992 25foot Excella so it is getting to the point that things are breaking down and need replacing.
Thanks,
Gary

The newer ones work by adjusting the duration of the heat cycle and are considerably more complex than that. They also lie and pretend that the temperature is right at the setpoint even if it's a degree or two off. Makes people feel more comfortable.

1500 watts is about 5k BTU. Most people will find a 1500 watt space heater sufficient in their trailer. I don't think anybody would seriously carry six 1500 watt space heaters around to heat their trailer. Really... that's how absurd it is! Place six electric space heaters around your trailer. Now, make it so that they all turn on full blast at the same time. If that's "comfort" then then you need a 30k BTU furnace.
I challenge anyone to bring their trailer of any size and construction to my driveway this time of the year and conclude after the first night that a single 1500 watt heater is sufficient.

It really does depend on the trailer size and the weather conditions. We get temps in the teens and a strong wind on thanksgiving some years and in January every year. If the furnace isn't big enough then the trailer is going to be cold and not by just a couple of degrees.

BTW, my furnace is an NT30K #2040 with 22,500 Btu out and 30,000 Btu in rating. It measures 13in wide x 9.5in tall x 22in long, front to back. Draws 6.5Amps (ouch!)
If I downsize to the NT 20SE 2.8Amps, it will fit in the space with extra room to spare.
If I go with the NT-30SP 4.5Amps, it will be a tight fit top to bottom.
Smaller is easier and saves energy and I can always add another portable heat unit to the mix as needed.
I do think my decision is staring me in the face.....still....

Yep, the electrical draw is huge when you oversize. There is nothing good about too much heat. There is a lot of downside.

Well, we've lived in our trailer quite comfortably with a 1500W electric heater and the temperature in the upper teens. A strong wind could make a difference but we also had sleeping bags good to sub zero temperatures. Sizing a furnace for nighttime use is silly. As for the day, what are you going to be doing?

We never heat our home above 66 degrees. Usually it's set at 64 during the day and 62 at night. I'd like it at 58 at night but the plans hate anything less that 60 degrees and our heat pump system doesn't do well with recovery temperatures more than 2 degrees at a setting.

Is there a post on sizing your furnace? I have a 1960 Pacer (16 ft) and it has an old Coleman furnace. I don't know if it was the correct size. I would like to by something new or used and need an idea of what might b ein my ball park for size. I live in Canada but would not likely use it in the dead of winter.
Thanks!

Oh yeah, I came across this floor furnace from the UK. It would be sweet to use the original floor furnace hole instead of the newer Coleman spot under the sink. Whale RV - Products
